The Propagation Characteristics of Rubus ellipticus var.obcordatus

To study on the vegetative propagation of Rubus ellipticus var.obcordatus, we adopted seeds and cutting of R.ellipticus var.obcordatus collected from Longling Country, Yunnan Province, and studied the influences of the different storage conditions and seed coat treatments on its germination and the influences of different rooting powders and cutting time on its cutting survival rate by controlling experimental conditions. The result showed that low temperature was the key factor to seed storage. Low temperature(0~4 ℃) and cracking seed coats could raise germination rate of R.ellipticus var.obcordatus; shading had no significant influence on its germination; abt No.1 rooting powder could raise its cutting survival rate; the cutting survival rate was the highest from January to March, but the lowest in May; cutting propagation of R. ellipticus var. obcordatus was convenient to operate, but with low breeding survival rate and bad seedling quality. Its layerage generation was complicated to handle, but bring high breeding survival rate and better seeding quality.
