主 题：Scarification substrate germination domestication Stereospermum kunthianum
摘 要：The demand for medicinal plants at the origin of phyto-drugs,like all ethnobotanical plants,threatens their existence *** aim of this work was to determine suitable methods for optimizing the possibilities of regenerating Stereospermum *** achieve this objective,3 levels of mechanical scarification(light scarification,medium scarification and deep scarification)were applied to the seeds of this species using a rough instrument,and 5 days after germination,the seedlings were transplanted into 5 types of substrate to study their effects on seedling *** length of the seedlings was measured using a graduated *** results obtained showed that the best latency time was 2 days for average seed *** highest germination half-time was 4.00±0.06 days observed for average seed scarification,the highest germination speed was 22.50±1.00 and the highest germination rate was 100.00%±0.00%for average *** homogeneous substrate mixes black earth/woodsilk and Fine sand/woodsilk were more effective for seedling growth(1.9 cm/day in the juvenile state)and *** seed scarification is the most effective method for regenerating Stereospermum kunthianum,and the black earth/wood shavings substrate mix is the best for its cultivation.
