Reproductive biology has been widely applied to the effective conservation and cultivation of species. In the current study, pollen germination and pollen tube elongation were carried out in several chosen plants species of Agra, Uttar Pradesh, for its reproductive success. All plants are helpful the making herbal medicines and belong to family Malvaceae and Papaveraceaea. Average pollen germination percentage was determined to be 58% with 55.03 ± 5.01 µm long pollen tubes in Hibiscus rosasinensis followed by Sida acuta (55%), Malva marutina (50 %) and Argemone
maxicana (47%) with 50.03 ± 4.01, 55.03 ± 2.5 and 55.03 ± 2.02 µm long pollen tubes, respectively. Pollen grains were found to be three colporate, spheroidal spiny exine, and 4-zonocolpate and reticulate. Under a light microscope, pollen dimension and pollen tube elongation were measured using an ocular micrometre. The present work focused on pollen tube length and pollen germination in chosen plants species in order to its reproductive success. |
