Reproductive Biology and Breeding System of Aconitum balfourii (Benth) Muk: A High Altitude Endangered Medicinal Plant of Garhwal Himalaya, India

摘要

Aconitum balfourii (Benth) Muk an endangered medicinal herb of high altitude region was studied for reproduction biology. Controlled pollination studies were also conducted on plants grown under hothouse. Observation reveals that ravine and scree wild habitats of alpine region had better flowers and seed production. Furthermore, hot house grown plants had far more superiority over wild populations for flowers and seed production. Protandry type of dichogamy was observed and is viewed as an anti-selfmg mechanism. In general, higher pollen germination was achieved comparatively at low concentrations of GA_3, IAA and IBA (1 ppm). Tube elongation was maximum upto 65 mum in IAA 1 ppm and 63 mum in IAA (5 ppm) and sucrose 5%. Dark condition along with violet color
