| | Regeneration of Sugarcane genotypes Under Different Level of Sodium Chloride Salt | Author : Kuasha Mahmud, Nadira Islam, Asish Kumar Ghose, Md Abdul Azim, Md Rashedur Rahman Rajib and Md Jahirul Islam | Abstract | Full Text | Abstract :The effects of Murashige and Skoog medium supplemented with different Sodium Chloride salt (NaCl) concentrations (0, 50, 100, 150, 200, 250 and 300 mM) containing 2, 4-D (3 mg/l) along with green coconut water (10%) on explants (leaf sheath) of four sugar-cane genotypes were aimed for their callus formation ability and production of embryogenic callus. Besides, regeneration potential-ity of sugarcane genotypes including shooting and rooting ability under different levels of NaCl concentrations (0, 50, 100, 150, 200, 250 and 300 mM) was evaluated. MS medium supplemented with 50 mM NaCl produced the highest callus (83.33%) in Isd 16 variety followed by BSRI Akh 41 (83%) and Mutant CC 37 M5 produced the lowest (66.66%)). But no callus was produced supplemented with 300 mM NaCl in all genotype. The highest shoot and root regeneration (91% and 92%) were obtained from MS medium fortified with 50 mM NaCl containing shooting media combination BAP (6-Benzylaminopurine) 2 mg/l + KN (Kinetin) 1 mg/l and rooting media NAA (1-Naphthaleneacetic acid) 5 mg/l respectively in BSRI Akh 41. On the other hand, little or no shoot and root were initiated from Isd 16, CC37 M5 and BSRI Akh 42 under above mentioned shooting and rooting media. Callus, shoot and root as well as regeneration ability of plant is highly correlated with callus, shoot and root formation. Significant differences were observed for callus, shoot and root regeneration capacity among all the four genotypes. It revealed that callus, shoot and root regeneration performance ability was decreased by increasing of NaCl concentration levels. |
| | A (Not) New Way to Cope with the Diseases | Author : Giovana Beger | Abstract | Full Text | Abstract :The rising world population is getting agriculture even more intensive, with the use of fertilizers and products to pests and dis-ease control. Due to the vast global information with the Internet, even more, people are looking for healthy products, more specifi-cally organic fruits and vegetables. A problem present in the pro-duction is the occurrence of diseases in the field and post-harvest, getting production losses to the farmer and the seller. The most used way to cope with the diseases is the usage of chemical fungi-cides, since copper- and sulfur-based formulations until the novel synthetic compounds. These cannot be used on organic farms. |
| | Effect of Different Chemicals on Eliminating the Dormancy Period of Freshly Harvested Seed Potatoes | Author : Muhammad Junaid Zaghum, Ali Zohaib, Muhammad Nouman Khalid, Ghulam Muhy Ud Deen, Armaghan Ahmad and Syed Sajid Hussain Zaidi | Abstract | Full Text | Abstract :A study was conducted to investigate the response of freshly harvested seed potatoes treated with Sugar (C12H22O11), Gibberellic Acid (C19H22O6), Thiourea (CH4N2S), and Ethanol (C2H5OH) to find out which chemical treatment has more effectiveness for the elimi-nation of dormancy period. Freshly harvested seed potatoes were collected from Plant Virology Section Research Area, Ayub Agri-cultural Research Institute, Faisalabad. Solanum tuberosum is a perennial because it is commercially propagated from tuber. In seed potato the normal dormancy period is 7-19 weeks. Results shows that treatment of 300g sugar powder in 600ml water eliminates the dormancy within 12-16 days at open light condition. Treatment with 600g sugar powder in 600ml water breaks the dormancy within 17-18 days at open light. Treatment with 300g sugar powder dry coating on wet surface of tuber eliminate the dormancy within 18-24 days at dark condition. Treatment with 1% TU and 1g GA3 in 1000ml solution can eliminate the dormancy within 18 days at open light and dark conditions. 250ml solution of EtOH can eliminate the dormancy period within 24-26 days at open light and semi dark condition. The application of dormancy breaking chemicals such as sugar, gibberellic acid, thiourea and ethanol induces metabolic changes that lead to dormancy elimination and also from those occurring when dormancy is eliminate naturally. The present study exposed that under open light condition treatment of 300g sugar powder in 600ml water solution gave best results of tubers sprout-ing as compared to other treatments. |
| | Management of Pink Bollworm Pectinophora gossypiella (Saunders) Using Mating Disruption Pheromone (PB Rope L) in Cotton | Author : Roop Singh Meena, Pardeep Kumar, Bharat Lal Meena and Bhagwan Singh Meena | Abstract | Full Text | Abstract :The efficacy of mating disruption pheromone (PB Rope L) was evaluated against pink bollworm Pectinophora gossypiella (Saunders) to monitoring pheromone traps catches as well as by sampling of bolls to record larval population and damage levels in cotton fields during Kharif 2016 and 2017, in north zone of India. This experiment was conducted in large plot in 10.0 ha and 4.0 ha area reserved as control. The main field T1 and T2 divided into two subplots T1A and T1B, T2C and T2D of equal size. In each of the subplots, six quadrates approximately 10x10 meter in the center at equal distance were marked. The treated fields were compared with control fields, three to four insecticides sprays in T1A and T1B, whereas 6 spray in T2C and 9 sprays were applied in T2D. The dispensers reduced pink bollworm catches in pheromone trap and reduced larval population and crop damage. Results showed that moth catches were highly suppressed in the treated fields by installation of the dispensers @ 685 PB Rope L at 50 days after crop sowing. Damage percentage was significantly reduced in treated fields as compared to control fields; Significant difference was observed in average seed cotton yield/ha. This study recommends the use of single application of pheromone dispenser at 50 days after crop sowing. These Rope were sufficient to maintain the moth catches and percent green boll infestation at the lowest level as compared to untreated field. |
| | Preparation and Quality Evaluation of Low-fat Mayonnaise by Using Hydrocolloid Gums and Olive Oil | Author : Aaysha Ihsan, Hamda Javed and Muhammad Umar Javed | Abstract | Full Text | Abstract :Commercial mayonnaise contains 70-80% oil that becomes the reason of many health problems. This study was conducted by keeping in view the most recent trend and its problems. The principal objective of this research was to establish stable mayonnaise with low fat by using hydrocolloid gums (xanthan gum, corn starch) as a fat replacer with olive oil which are also cost effective. So due to health and economic concerns, the formulation of healthier versions of mayonnaise are developing that have low fat with same stability and price like their counterparts. It is also important to properly choose the concentration of your food gum in terms of the consistency of LF mayonnaise, which can result in an elastic gum if you add too much gum. If you add too little gum and the whole water is not bound permanently then, the mayonnaise can appear as a fluffy, airy mass. Treatments T2 (0.50% XG), T3 (0.75% XG), T4 (1% CS) and T7 (XG:CS) showed the better results as compare to traditional full-fat mayonnaise in terms of physical and sensory characteristics. With the increased level of hydrocolloid, calorie contents decreased but high level of gum can also affect overall ac-ceptability of low-fat mayonnaise. This research has significant effect in industrial/commercial level. |
| | Molecular Regulation in Seed Development Influencing the Fiber Growth in Gossypium hirsutum L. | Author : Muhammad Junaid Zaghum, Muhammad Nouman Khalid, Muhammad Zia ul Haq, Muhammad Tashfeen Gul, Ifrah Amjad and Muhammad Irfan | Abstract | Full Text | Abstract :Cotton crop is mostly cultivated for fiber production, source of livestock meal and seed oil. The oil of cottonseed used as edible oil around the World after colza and soybean oil and ranked 3rd Worldwide. The quality of cottonseed mainly dependent on protein, oil content, minerals and seed composition. Therefore, However, it is necessary to keeping the acceptable oil content quality. The nutritional value and industrial usage of cottonseed is influences with formation of fatty acids in seed. There is still much unidenti-fied physiological processes and genetic structures that enforce the levels of these metabolites in cottonseed. The expression of homoeologous genes is inappropriate when the epigenetics and intergenomic differences are induced by the genomic association of A and D progenitor in allotetraploid cotton. Signaling factors associated with cell growth, adaptation and development controls the expression of RNA during transcription. Transcriptional factor of MYB-domain encoded by degraded homologous mRNAs during mediation of miRNA that are utilized for fiber development and leaf initiation. From last many decades, scientists work on enhance-ment of seed and fiber quality. The main nutritional function of cottonseed is oil content and very extensive studies are ongoing on this value-added aspect. Major advancement is taken to increasing the quantitative amount of fatty acid accumulation, which is yet needed to strengthen the requirement and increases the demand of oil seeds. The main objective of this study is to understand the physiologically perspective of seed development and oil content accumulation. To understand the fiber biology to interpret the molecular events which activate or suppress the initiation of fibers from epidermis cells. Because of large genomic size, presence of low-density genetic map and restrictions in cotton transformation. |
| | Nanofertilizers in Agriculture | Author : Kaila Tara Meghana, MD Wahiduzzaman and Golla Vamsi | Abstract | Full Text | Abstract :Global population is rapidly increasing and is predicted to reach 9.6 billion by 2050 and the limited resources tend to push the sec-tor forward demanding the development of a highly efficient agriculture thus allowing reduction of worldwide poverty and hunger [1]. To meet the food demands of this growing population the agriculture sector is being pressurized to assure food security. Hence chemical fertilizers are being considered as an inevitable source of plant nutrition for improving the crop production. This lead to a notion in farmers that using higher quantities of chemical fertilizers gains higher crop yields.However, only less than half of the amount of applied fertilizers will be utilized by the crop whereas the remaining amount of fer-tilizer which is intended to be taken up by plant may get lost through leaching, become fixed in soil or contribute to water pollution which is even worse. According to recent statistical reports it has been observed that the key macronutrient elements Nitrogen, Phos-phorous and Potassium applied to the soil are lost at a rate of 40-70%, 80-90% and 50-90%, respectively, thus causing a considerable loss of applied resources [2]. Additionally, farmers tend to apply fertilizers repeatedly in order to achieve yields at desired levels, this overdose of chemicals counter acts and lead to decreased soil fertility and increased salt concentrations thereby causing future crop losses. Furthermore, irregular use of fertilizers without control on nutrient release patterns causes deterioration of product quality. Therefore, developing slow or controlled release fertilizers plays a crucial role not only in enhancing the crop production, productiv-ity and quality, but also helps towards upgradation of sustainability in agricultural production. Given the unique properties of nano-materilas such as high surface-to-volume ratio, controlled-release kinetics of nutrients to the targeted sites and sorption capacity, nanotechnology has a high importance for designing and using of new fertilizers. Nanofertilizers are nutrients encapsulated/coated with different types of nanomaterials for the control and slow delivery of one or more nutrients in order to satisfy the imperative nutrient requirements of plants [3]. These “smart fertilizers” are now being regarded as a promising alternative, to an extent that they are to be considered as preferred form of fertilizers over the conventional ones in several cases. |
| | Research on the Effect of the Wall Materials of Microcapsules on the Heat Storage Process of the Phase Change Material in Microcapsules | Author : Kuanbing Caozhu, Xiujun Yang and Changfa Ji | Abstract | Full Text | Abstract :The wall materials of the microcapsules affect the heat storage process of the phase change material in microcapsules with a plate. In this paper, Fluent CFD software is used and solidification/melting model is chosen to carry out the simulation of the heat storage process of the phase change material in microcapsules under the condition of four different wall materials of microcapsules. The physical model of the phase change microcapsules with equal spacing in combination with a plate is established and the liquid vol-ume fraction and average temperature of the phase change material in microcapsules with time are analyzed. It can be concluded that when the phase change material is pure paraffin and its initial temperature is 324.15K, through the comparison of the liquid volume fraction of the phase change material in the process of phase change and the calculation of the heat storage capacity of phase change, it is concluded that when the wall material of microcapsules is urea formaldehyde resin, the amount of heat absorbed by the phase change material in the process of phase change is the most enormous, which is 7891.60901J. Thus, the urea formaldehyde resin is chosen as the most suitable wall material of microcapsule. |
| | Outcrossing Characteristics and Yield Potentiality of Restorer Line of Rice | Author : Md Nur Alam Siddique, MA Khaleque Mian and Umakanta Sarker | Abstract | Full Text | Abstract :The present experiment was undertaken to study the statistical and genetic parameters, correlation coefficient, path coefficient of ten characters of restorer lines in rice and multivariate analysis of 18 characters of restorer lines in rice. Characters wise summaries were given below. Mean sum of square for anther length, anther breadth, pollen diameter, % pollen sterility, duration of anthesis, number of panicles per hill, days to maturity, number of filled spikelet per panicle, % spikelet sterility and grain yield per hill were highly significant due to genotypes in restorer line indicating wide range of variability among the restorer line for this traits. Low environmental effect and additive gene action were found in all these traits because s2g and s2p and the GCV and PCV were close to each other. Heritability, GA and GAPM was found high and moderate; all the traits indicate these traits will be effective for selection. High heritability, low GA and GAPM showed that both additive and environment influence of anther breadth, spikelet sterility percent and pollen diameter. Anther length showed significant positive correlation with anther breadth and significant negative correlation with duration of anthesis, number of filled spikelets per panicle and grain yield per hill both genotypic and phenotypic level and only significant positive genotypic correlation with pollen diameter and % pollen sterility. Anther breadth showed significant positive genotypic and phenotypic correlation with % pollen sterility and significant negative genotypic and phenotypic correlation with duration of anthesis and significant positive genotypic correlation with pollen diameter. Pollen diameter showed significant positive genotypic cor-relation with days to maturity and significant negative genotypic correlation with % pollen sterility, duration of anthesis, number of panicles per hill, spikelet sterility percent and grain yield per hill. % Pollen sterility showed significant positive s2g and s2p correla-tion with number of panicles per hill and significant negative s2p correlation with duration of anthesis. Duration of anthesis showed significant positive s2g and s2p correlation with days to maturity. Number of panicles per hill showed significant positive genotypic and phenotypic correlation with grain yield per hill and significant positive genotypic correlation with spikelet sterility percent. In case of genotypic correlation days to maturity showed positive correlation with number of filled spikelets per panicle and spikelet sterility percent, and showed positive phenotypic correlation with spikelet sterility percent. Number of filled spikelets per panicle showed significant positive genotypic and phenotypic correlation with spikelet sterility percent and grain yield per hill. Significant positive genotypic correlation was observed in between spikelet sterility percent and grain yield per hill. High positive direct effect on grain yield per hill was observed in case of number of filled spikelets per panicle and number of panicle per hill and similar lower effect in case of duration of anthesis, anther breadth and pollen diameter. I observed days to maturity, anther length and % spikelet sterility had a direct negative effect on grain yield. Number of filled spikelets per panicle and number of panicles per hill was found as a main yield contribution character of the restorer line of rice because those characters have considerable s2g, s2p, GCV and PCV and others character. |
