The orthogonal experiments, in-cluding the selection of basal medium, embryo age and other factors such as sugar, benzyladenine (BA), naphthalene acetic acid (NAA) and glutamine (Gln), were carried out. The results indicated that the optimal medium for embryo culture was Monnier medium supplemented with NAA (0.001 mgL-1), BA (0.1 mgL-1), sugar (50 gL-1), and Gln (400 mgL-1), with a germination rate of 91.7% at least; the optimal embryo age was 50 d; and Gln had significant effects on the germination rate of embryo. Moreover, the optimal medium for subculture was MS+BA (2 mgL-1)+NAA (0.001 mgL-1)+Gln (0.5 mgL-1), with the propaga-tion coefficient of 3.6 at least.展开更多
