| 摘 要： | 采用不同遮荫方式下的高羊茅为试验材料,分别在完全光照和针叶、灌木、阔叶树木3个遮荫条件下评价草坪质量,并测定其主要形态指标、生理生化指标。结果表明:随着遮荫程度的提高,高羊茅的形态上出现株高增加、叶片变长、茎秆纤细、分蘖数减少;同时,叶绿素a和叶绿素b含量都有所增加,而叶绿素a/b的比值有所下降。生理上表现为膜透性增大,膜脂过氧化物(MDA)含量增加,可溶性糖含量减小,游离脯氨酸含量增加。对高羊茅遮荫伤害程度:针叶灌木阔叶树木。

| Abstract: | Taking Festuca arundinace as test material,leaves of Festuca arundinace were treated with different shade conditions of conifer,shrub and hardwood,the changes of morphology and physiology in Festuca arundinace leaves under different shade conditions were studied.The results showed that higher,leaf length,stem diameter,chlorophyll a,chlorophyll b,membrane permeability,MDA,soluble sugar and proline increased.However,tilling,chlorophyll a/b and soluble sugar decreased in Festuca arundinace leaves under shade treatments.The degrees of injury to Festuca arundinace were conifer > shrub>hardwood. |
