NG是一种非生长激素类的化学药剂。经试验证明:NG是枣组织培养中一种有效的新型生长调节物质。以H培养基为基本培养基,附加70％NG100mg·l~(-1),可显著地提高枣试管继代繁殖材料发芽数,在75～200mg·l~(-1)范围内,随浓度的提高,单芽梢生长量有显著下降的趋势,大于75mg·l~(-1)抑制生根。25mg·l~(-1)、50mg·l~(-1)的NG有利于枣试管继代繁殖材料生根,使芽梢生长粗壮,单株芽梢的总生长量也显著增加,而且用作继代繁殖材料利用率高。
NG is a non-growth hormone chemical. Proved by experiment: NG is an effective new growth regulator in jujube tissue culture. With H medium as the basic medium, adding 70% NG100mg · l ~ (-1) could significantly increase the germination number of the reproductive material of jujube tube in the range of 75 ~ 200mg · l -1, , The growth of single buds had a significant decline trend, more than 75mg · l ~ (-1) inhibited rooting. 25 mg · L -1 and 50 mg · L -1 NG were beneficial to the rooting of the reproductive materials of jujube in vitro, which made the shoots grow thickly and the total growth of shoots per plant increased significantly, Successive breeding materials utilization.
