摘要
以2、3a生金钱松小苗为试材,研究不同程度的遮荫(0%、30%、50%、70%、95%)对金钱松小苗生理特性的影响。结果表明:随着遮荫程度的加强,叶绿素a、叶绿素b、叶绿素(a+b)在遮荫70%处理上升到最大值,在遮荫95%处理下降,a/b整体呈现下降趋势,POD、叶片相对含水量、可溶性蛋白、脯氨酸含量均有不同程度的升高,得出金钱松幼苗在遮荫30%～50%对其生长良好,在遮荫95%处理下生长受到抑制。
The effects of shade degrees 95% ,70% ,50% ,30% and 0% of full sunlight on the physiological characteristics of different ages of Pseudolarix kaempferi seedlings were studied. The results indicated that chlorophyll a content, chlorophyll b content and chlorophyll content increased,a/b content reduced,POD content,leaf water content,proteins, and proline in leaves of the Pseudolarix kaempferi increased to different degrees with the extension of shade stress, It showed that Pseudolarix kaempferi seedlings to light intensity had a strong ability to adapt to it.
