Embodiment Construction
[0018] Select leaves of jujube tissue culture seedlings with a seedling age of 20 days, cut 5 to 8 cuts on the vertical veins with sterilized scissors on the aseptic operating table, and then inoculate them on the embryoid body induction medium (MS + maltose 15 ~ 25g / L+agar 3.0~5.0g / L+TDZ5.0~10.0mg / L+AgNO 3 1.0~2.0mg / L), add colchicine 15~20mg / L in the culture medium at the same time, cultivate in dark for 40~50 days, and differentiate embryoid bodies from jujube leaf callus; the differentiated embryoid bodies Transfer to the hormone-free medium of MS + sucrose 40g / L + hydrolyzed casein 500mg / L, culture under light, and the embryoid body develops into a somatic embryo; the somatic embryo is detected by chromosome ploidy, and the homotetraploid is screened out. The pH value of the medium is 5.0-6.0, and the culture temperature is 25-30°C.
