Studies on pollen performance in some endangered medicinal and aromatic plants of cold desert Ladakh
Journal Title: Environment Conservation Journal - Year 2024, Vol 25, Issue 3
Abstract
The study was carried out at the Trans-Himalayan Herbal Garden, located at the National Institute of Sowa Rigpa-Leh, from 2021 to 2023. An assessment of pollen viability was conducted using seven significant medicinal and aromatic plants from the Ladakh region. Analysis of pollen vitality was conducted using the acetocarmine staining technique. The pollen viability of Inula racemosa Hook. f. ranged from 91.08 ± 1.39 % to 82.44 ± 1.48 % in Ephedra gerardiana Wall. Among the genus Inula racemosa, the highest percentage (91.08%) of viable pollens indicates a normal meiosis, whereas Ephedra gerardiana recorded the lowest percentage. Among the chosen species, Inula racemosa, Verbascumthapsus, Hyoscyamus niger, and Dracocephalum heterophyllum stand out for their exceptional pollen viability. These species can be effectively utilized for conservation purposes and as male parents in hybridization. The result for the average pollen density varied from 1533.07 ± 106.32 in Capparis spinosa L. to 276.00 ± 10.20 in Dracocephalum heterophyllum.
