| 摘 要： | 研究了20%,40%轻度遮荫处理对紫羊茅叶片叶绿素含量和生长的影响。结果表明：遮荫60d,随光强的减弱,叶片中叶绿素a、叶绿素b和总叶绿素含量显著增加,20%和40%遮荫处理叶绿素总量分别比自然光照增加了8.80%和10.87%。紫羊茅分蘖能力和各部分植物量增量明显提高,20%和40%遮荫处理总干重增量分别比自然光照提高15.46%和35.00%。随遮荫强度增加,植株高度增加。遮荫能显著提高植株的含水量,40%遮荫处理植株含水量达到76.39%。

| Abstract: | The effect of lightly shading(20% and 40%shading)on chlorophyll content and growth of Festuca rubra was studied.The results showed that the content of chlorophyll a chlorophyll b and total chlorophyll were increased significantly after 60 days shading treatment and total chlorophyll content in 20% and 40% shading treatments were increased by 8.80% and 10.87% respectively.The ability of tillering and the biomass were also increased along with the shading intensity,and the total dry matter per plant in 20% an... |
