摘要:

采用水培方法,以清水培养为对照,研究了不同营养液配方对含羞草(Mimosa pudica)生长发育的影响。结果表明,含有0.9446 g·L-1Ca(NO3)2.4H2O、0.8088g·L-1KNO3、0.1495g·L-1NH4H2PO4和0.4929 g·L-1 MgSO4·7H2O的营养液(配方B)所处理植株的各项形态指标均明显优于其它配方,叶绿素含量和过氧化氢酶活性也高于其它配方。而丙二醛(MDA)的含量与其它配方相比差异不显著。

Abstract: Effects of different nutrient solutions on the growth and development of Mim osa pudica were
studied under solution culture conditions. The results indicated that different nutrient solutions had significant
effects on the growth and development ofM im osa pudica. The p lants in B treatmentwhich include 019446 g·
L -1 Ca(NO3)2.4H2O, 018088 g·L -1 KNO3 , 011495 g·L -1 NH4H2PO4 and 014929 g·L -1 MgSO4 ·
7H2O had bettermorphological characters than that in other treatments, and the content of chlorophyll and
CAT activity were also higher than that in other treatments, but the content ofMDA showed no significant
difference in all treatments.

Key words: Mimosa pudica, Nutrient solution, Growth and development
