| 摘 要： | 以日本引进的勋章菊为材料进行抗旱性试验,测定干旱胁迫下叶片脯氨酸(Pro)含量、丙二醛含量(MDA)、相对电导率、总叶绿素和可溶性蛋白含量等生理指标的变化。结果表明:随着干旱胁迫天数的增加,脯氨酸含量明显升高;丙二醛含量、相对电导率呈缓慢上升趋势,细胞膜透性增大;叶绿素总含量、叶绿素a、叶绿素b、类胡萝卜素呈先下降后上升再下降的趋势。盆栽勋章菊在连续10 d不浇水的条件下,复水后仍可成活生长,表明勋章菊具有很强的抗旱性,为勋章菊在应用过程中低成本养护提供了参考。

| Abstract: | With Gazania rigens L.introduced in Japan as material,the contents of Pro and MDA,electrical conductivity rate,chlorophyll content and the content of soluble protein in leaves were measured under drought stress.The results showed that with the prolonging of drught stress time,the content of Pro obviously rised,the content MDA and electrical conductivity rate showed slowly rising trend,cell membrane became bigger.Chlorophyll,Chlorophyll a,Chlorophyll b, carotene contents decreased firstly,then increased,at last decreased again.After Pot-cultivating Gazania rigens L.did not water for 10 days then water.They still growing very well.Above showed that Gazania rigens L.had a strong fighting against drought.Those provided the design with Gazania rigens L.had a low cost a scientific evidence. |
