为了探明盐胁迫对萱草生长及其相关生理特性的影响,采用水培试验,对重瓣大花萱草(Hemerocallis fulva var. florepleno)、玫瑰红萱草(Hemerocallis fulva var. rosea)、黄花菜(Hemerocallis citrina)和大花萱草(Hemerocallis hybrida)在NaCl质量分数分别为0.0%,0.2%,0.4%,0.6%,0.8%,1.0%的水溶液下的生长及相关生理变化进行了研究.结果表明:1) 4个萱草材料在0.2%～0.6%的NaCl胁迫下,叶片伤害指数较小,根的生长只受到了轻微的抑制,胁迫后第20天,平均新根数≥3.67条;在0.8%～1.0% NaCl的胁迫下,叶片伤害指数较大,根系生长受到严重的抑制,并且还表现出了一定的基因型差异.以伤害指数和新根数量衡量...

The effects on root and leaf growth of four Hemerocallis clones （Hemerocallis fulva vat. florepleno, Hemerocallis fulva var.rosea, Hemerocallis citrina, Hemerocallis hybrida） treated with different NaCl concentrations under water culture have been researched. The main results were as follows： （1） The four Hemerocallis clones treated with 0.2%-0.6% NaC1 showed lower injury index, their new root number ≥ 3.67, the injury of root and leaves were slighter; When treated with 0.8% - 1.0% NaCl, the four Hemerocallis clones showed higher injury i...
