5 g/L+ inositolum 100 mg/L+casein 100 mg/L is the optimal culture medium for induction of embryogenic callus.

Based on single-factor screening experiments of embryogenic callus induction and differentiation of Chinese narcissus,comprehensive survey has been carried out with orthogonal experimental design.

The optimal tissue culture system for embryonic callus induction and plant regeneration in blue grass has been set up by doing this experiment about callus induction and plant regeneration from mature seeds of Blue grass,which were cultured on MS basal medium supplemented with 2,4-D.

The result showed much difference between embryonic callus and non-embryonic callus.

) were obtained from young inflorescence culture by subculturing the calli in organic nitrogen rich media and were used to promote the embryogenic suspension cultures.

Cryopreservation of embryogenic calli by vitrification and plant regeneration via somatic embryogenesis in litchi;

The change of the chromosome number in the embryogenic calli and in the process of the somatic embryogenesis in litchi;

After subculture of 2 years, embryogenic calli were observed on the somatic embryos.
