(2) Different quality characters existed obvious influence with picking tip time,Variability of soluble sugar was the largest,variabilities of starch,protein and dried rate were larger,variabilitie.

Objective: To set up the optimums for the stem tip tissue culture of Chrysanthemum morifolium cultivated in Anhui Province.

There are differences in the yield,qualities and economic benefits of the stem tip among the vegetable sweetpotato varieties.

Cymbidium hybridum stem tip was used as explant and MS was used as medium to explore the effects of external hormone on green protocorms differentiation,multiplication and adventitious root forming.
