SYNTHETIC SEED PRODUCTION POSSIBILITIES FROM MERISTEM AND SOMATIC EMBRYO IN LEMON BALM (Melissa officinalis) | Author : Anil Mehmet BALTACI, Mehmet ARSLAN | Abstract | Full Text | Abstract :Lemon balm (Melissa officinalis), an essential oil bearing perennial herb in the Lamiaceae family. This study was conducted to obtain synthetic seeds from axillary buds and somatic embryos of lemon balm. Germination capacity of the synthetic seeds was tested in vitro and in vivo conditions. Two different methods, direct use of axillary buds and somatic embryos with 4% sodium alginate encapsulation were used. The highest callus formation rate was obtained from 1.0 mg/l 2,4-D + 1.0 mg/l NAA + 0.5 mg/l KN and 1.5 mg/l 2,4-D + 1.0 mg/l IAA + 0.5 mg/l KN applications with 62.51%. To obtain somatic embryos calli were transferred on MS with 0.5 mg/l KN. Synthetic seeds form axially bud and somatic embryos were obtained by covering 4% sodium alginate and dropping in 100 mM calcium chloride. Germination potential of synthetic seeds was tested in MS medium and peat. No germination was observed in peat, but only 15% germination of the synthetic seeds from axillary buds was observed on MS medium. |
| ADAPTATION OF SOME ALMOND CULTIVARS UNDER USAK ECOLOGICAL CONDITIONS | Author : Ercan YILDIZ, Çigdem EROL PERDAHCI2 | Abstract | Full Text | Abstract :The almond culture is very old in Turkey, but it has not reached the importance as the other major fruit species, until recently. However, in recent years, new almond orchards in Turkey
have been established with late-flowering foreign cultivars, and the almond production has increased. This study was carried out to determine the phenological and fruit quality characteristics of some almond cultivars (Nonpareil, Texas, Drake, Ferragnes and Ferraduel) in Usak ecological conditions. According to the findings, Ferragnes and Ferraduel were found
to be the latest flowering cultivar on March 26, while Nonpareil was the earliest flowering one on March 16. Flowering period of cultivars changed between 14 and 17 days. The fruit
set rates were significantly higher in the Ferragnes and Ferraduel varieties (30.7% and 30.8%, respectively) than in the other cultivars. As a result of pomological analyzes; the heaviest fruits were obtained from Ferragnes and Ferraduel (4.15 g and 4.02 g, respectively), and the smallest from Texas (1.62 g) and Nonpareil (1.67 g). The kernel percentages of Nonpareil and Texas was highest with 53.5% and 52.7%, respectively, while the lowest rate was found in Ferraduel with 25.2%. In general, it is suggested that the Ferragnes cultivar which flowered after 10 days from other almond cultivars in order to protect from the late spring frosts frequently encountered in the Usak province, especially because of the fruit yield and kernel ratio compared to Ferraduel cultivar. |

(Raphanus sativus L. var. radicula) and turnip (Brassica campestris L. subsp. rapa)] on Amaranthus retroflexus L. and Portulaca oleracea L. were investigated in field conditions.
The turnip and radishes in the flowering period were harvested and the remains of the plots were tilled with a diskharrow and the corn was planted in all plots. The density of Amaranthus
retroflexus and Portulaca oleracea in corn was counted for 60 days with 15 days intervals. According to the results, it was determined, the radish and turnip residues that were
incorporated with soil prevented by approximately 45-52% the germination and growth of Portulaca oleracea and Amaranthus retroflexus up to the first 30 days and the effects have
been eliminated after this date. |
| ANTIFUNGAL EFFECTS OF ESSENTIAL OIL FROM Ocimum basilicum L. | Author : Ayse USANMAZ BOZHÜYÜK, Saban KORDALI | Abstract | Full Text | Abstract :Ocimum basilicum L. essential oil was analyzed for its antifungal effects on 9 phytopathogenic fungi comprising six Fusarium species (Fusarium equiseti, Fusarium graminearum, Fusarium oxysporum, Fusarium moniliforme, Fusarium sambucinum and
Fusarium semitectum) and Rhizoctonia solani, Alternaria solani and Verticillium dahliae mycelial growth in vitro petri experiments.
The results of the analyses showed that concentrations 15 and 20 µL petri-1 of O. basilicum essential oil completely inhibited mycelial growth of the F. sambucinum fungi and demonsrated that its antifungal effects were higher than the commercial fungicide "Captan". Different concentrations of the essential oil (5, 10, 15 and 20 µL petri -1), significantly prevented the growth of all tested pathogenic fungi. The results also showed that the essential oil affected mycelial growth of all tested pathogenic fungi, ranged from 0.0 to 31.2 mm at all concentrations and these results confirm the antifungal activities of O. basilicum L. oil. The essential oil prevented the growth of 9 plant pathogens fungi from 23% to100%. With this study, it was determined that the essential oil of O. basilicum has the potential to be used as an antifungal substance. |

Genotypes Using SSR Markers | Author : Müge Özeren, Yasar Karakurt, Damla Güvercin | Abstract | Full Text | Abstract :The aim of the study was to determine the differences among avocado cultivars using SSR markers. Avocado is classified within the Persea genus in the Lauraceae family. In this study, five avocado cultivars grown in the Mediterranean Region obtained from the Western Mediterranean Agricultural Research Institute, in Antalya, Turkey and seven cultivars obtained from Japan have been used for the molecular analysis. As a result of
molecular analyses with 13 SSR markers, two main groups were obtained among avocado cultivars and both groups demonstrated 60 % similarity. In the study, a close correlation
was observed both between JP4 and JP6, and JP5 and JP7. Polymorphisms that could separate Zutano and Hass varieties were not obtained and these two cultivars were grouped
together. JP1, JP2, JP3, and Bacon varieties formed a single sub-group. The total number of alleles and specific allele numbers were determined as 152 and 53 respectively. The band sizes ranged from 179 to 283 bp. Polymorphic Information Content (PIC) changed between 0.03 and 0.85. The results will be usefull in the characterization of the avocado genotypes
and comparison of the genetic collections, in the determination of the distribution areas of avocado genotypes and in the avocado breeding programs for choosing parents. |

| BIOMASS ENERGY POTENTIAL FROM AGRICULTURAL PRODUCTION IN SUDAN | Author : Bahadir Demirel, Gürkan Alp Kagan Gürdil, Omsalma Gadalla | Abstract | Full Text | Abstract :The objective of this study is to determine the agricultural residues potential regarding type and quantity in Sudan. Sudan was divided into six main regions.The amounts of crops cultivated in Sudan in tons of dry matter per year, were calculated and estimated using production data crops with Food and Agriculture Organization Statistical Databases of United Nation (FAOSTAT) for the 2016 seasonal year. The annual gross potential of agricultural residues was determined by using residue to product ratio. The energy potential of crop residues for eachregion was calculated by multiplication of the calorific values of agricultural residues with available residue amount. The total amount of unused agricultural crop residues was approximately 11.2Mt. It was found that the total calorific value of agricultural residues were around 154PJ for the production period of 2016 in Sudan. When regions were placed in order according to amount of agricultural residues, the top three regions of the country are central Sudan (4.5Mt), eastern Sudan (4.2Mt), and northern Sudan (1.4Mt). The major crops included in the ratioof the total calorific value were sorghum (43.2%), mango (28.1%), millet (13.6%)and wheat (6%). |
