植物生长调节剂对银杏悬浮细胞生长和黄酮糖苷含量的影响

Effects of Plant Growth Regulators on Suspension Cell Growth and Formation of Flavonol Glycosides in Ginkgo

试验表明：Ｎ_２（ＭＳ＋１ｍｇ ．１^（－１）ＮＡＡ＋２ ｍｇ·１^（－１）ＫＴ）和Ｂ３（ＭＳ＋１ｍｇ ．１^（－１）ＮＡＡ＋２ ｍｇ ．１^（－１）６－ＢＡ）培养基最有利于银杏悬浮细胞干重的积累。 Ｎ_２和 Ｂ_２（ＭＳ＋ １ｍｇ．１^（－１）ＮＡＡ＋ １ｍｇ·１^（－１）６－ＢＡ）培养基有利于黄酮糖苷积累，而ＧＡ_３、２，４－Ｄ、ＺＴ处理均不利于黄酮糖苷积累。

Experiment proved that N_2 media(MS supplemented with 1 mg' l^(-1) INAA and 2 mg. l^(-1) 'KT)and B_3 media (MS supplemented with 1 mg.l(-1) NAA and 2 mg.l^(-1) 6 - BA) could promote the accumulation of suspension cell he weight. N_2 media and B_2(MS supplemented with 1 mg.l^(-1) NAA and 1 mg.l^(-1) 6 - BA) were bene ficial to the formation of the flavonol glycosides. GA_3,2,4-D and ZT beatments didn' t promote the formation of flavonol glycosides.
