对甜叶悬钩子的茎尖微繁技术进行了研究。结果表明:在MS培养基中附加植物生长调节剂BA0 2～0 5mg·L-1和NAA0 2mg·L-1,诱导茎尖效果最佳,诱导率高达76%;在附加植物生长调节剂BA0 6mg·L-1和NAA0 3mg·L-1的MS培养基上进行丛芽继代培养,增殖倍数可达7 5倍;壮苗生根培养用1/2MS培养基附加植物生长调节剂NAA0 7mg·L-1和活性炭为佳。 We studied the shoot tip micropropagation technique of sweet clover. The results showed that BA0 2 ~0 5 mg · L-1 and NAA0 2 mg · L-1 were the best medium for inducing shoot tips in MS medium with the induction rate as high as 76%. After adding plant growth regulators BA0 6mg · L-1 and NAA0 3mg · L-1 on the MS medium for bud bud culture up to 7 5 times multiplication; strong seedling rooting culture with 1 / 2MS medium supplemented with plant growth regulator NAA0 7mg · L-1 and activated carbon is better.
