| 摘 要： | 随蔗糖浓度的提高,生姜试管苗的株高显著降低,而繁殖系数显著增加,蔗糖浓度超过80 g·L~(-1)时,繁殖系数则显著降低。不同蔗糖浓度处理生姜试管苗叶片及根状茎內源激素IAA、ZR变化较小;而GA则随蔗糖浓度的提高呈下降趋势;蔗糖浓度在20～50 g·L~(-1)范围内叶片ABA变化不大,而根状茎ABA则迅速降低,蔗糖浓度超过50 g·L~(-1),叶片ABA迅速增加,而根状茎ABA则变化不大。生姜试管苗根状茎形成与叶片及根状茎内源激素ABA/GA密切相关,相关系数分别为0.935 8和0.996 7。蔗糖浓度80～110 g·L~(-1)时,叶片ABA/GA在1.0～1.4之间,诱导根状茎效果较好。

| Abstract: | With sucrose concentration increasing, the height of tube-ginger plant decreased, while propagation coefficient significantly increased. When sucrose concentration was more than 80 g·L~(-1), propagation coefficient decreased. In different treatments, concentrations of IAA and ZR varied little, but GA declined with sucrose concentration increasing when sucrose was from 20 g·L~(-1) to 50 g·L~(-1). Concentration of ABA in leaves varied a little but ABA in rhizome declined sharply on the contrary when sucrose c... |
