ABSTRACT
This study was aimed to find the optimal conditions for seed propagation of Fritillaria cirrhosa in the plateau region in order to summarize the best sowing time and method of artificial propagation. Seeds were stored in appropriate environment. After the seeds matured, the seedbed of F. cirrhosa was treated with cattle dung humus and small shed. The results showed that early March is the best sowing time and cattle dung humus with a thickness about 1 cm is the best coving for propagation of F. cirrhosa; the growing period of film propagation (FP) is about 160 days each year compared with that of control about 50-60 days, respectively. It was concluded that the propagating seeds in plastic greenhouses by using cattle dung humus as planting substrates, using sunshade nets for shading and keeping humidity by spraying can effectively prolong the growing period, improve the retention rate of annual bulbs and the production of F. cirrhosa.
ABSTRACT
Object To study the effect of plant growth regulator on medicinal constituents of Dendrobrium nobile Lindl Methods The root of D nobile was treated by immersing in solutions of plant growth regulator 6 BA and GA 3 Results and Conclusion Both plant growth regulator at certain concentration, resulted in an increase of total soluble sugar content, but without effect on the content of dendrobine GA 3 can significantly elevate the content of total alkaloid in D nobile
