| 摘 要： | 目的]研究Ca2＋对吊兰根系负向光性的影响。方法]在恒温条件下,对不同浓度CaCl2溶液中受单侧光照射后吊兰根的生长情况进行了研究。结果]水培液中的Ca2＋对吊兰根的生长和向性反应有显著影响;低浓度Ca2＋促进根的生长,高浓度Ca2＋抑制根的生长。其中,当Ca2＋浓度为0.4mmol/L时,吊兰根的生长和弯曲最为显著。结论]吊兰根的负向光性受内源与外源Ca2＋的综合影响。

| Abstract: | Objective] The aim was to explore the effects of Ca2＋ on the negative phototropism of Chorophytum comosum root.Method] C.comosum were cultivated in different concentration of CaCl2 solution with unilateral light illuminated.Rusult] The Ca2＋ in nutrient solution showed significant effect on the growth and tropic reaction of C.comosum;low concentration of Ca2＋ promoted root growth,while high concentrations of Ca2＋ inhibited the root growth.When the concentration of Ca2＋ was 0.4 mmol/L,the phenomenon of the negative phototropism and the root growth were the most obvious.Conclusion] The root negative phototropism could be concluded to the comprehensive effect of the endogenous and exogenous Ca2＋. |
