选用特早熟杏红荷包为试材，首次将果实发育期45天的胚培养成株，从发育55～59天的胚得到300余株壮苗，栽植于选种圃．提高特早熟杏胚培成首的技术关键主要是：①选择适宜的接种时期，在花后59天硬核期PF1值达0.9时采样接种；②选用改良Tuber培养基，附加BAO．2毫克／升；③经80天以上0～3℃低温处理，④在15℃条件下，增强光照炼苗，9月下旬气温较低时移栽．
Selection of early maturing apricot purse as test material, for the first time the embryo development of 45 days of embryo culture into a strain, from 55 to 59 days of embryo development to get more than 300 strong seedlings planted in the selection of nursery. The key to improve the early maturity apricot embryo culture is the first: ① choose the appropriate inoculation period, 59 days after flowering in the hard nuclear PF1 value of 0.9 when sampling vaccination; ② Selection of modified Tuber medium, with BAO. 2 mg / l; ③ After 80 days 0 ~ 3 ℃ low temperature treatment, ④ Under the conditions of 15 ℃, enhanced light hardening, late September when the temperature is low transplanting.
