摘    要:多年生花生在全光照至80%遮荫度的环境中都能生长,随着遮荫度的增大,其叶片面积和叶绿素含量均明显增加,净光合速率,呼吸速率和光补偿点均不下降,20%遮荫度的株鲜重与全光照下没有变化,80%遮荫度吏株鲜重降低了36%。

关 键 词:多年生花生  遮荫  生长

Abstract:Arachis pintoi plants grow under full sunshine or 80% shading intensity. With the increase of shading intensity, both leaf area and leaf chlorophyll content increased significantly, but leaf net photosynthetic rate, respiration rate and lignt compensation point decreased. No obvious difference was detected in the fresh weight of plant between 20% shading treatment and full sunshine. However, the 80% shading treatment reduced the plant fresh weight by 36%.
Keywords:Arachis pintoi  shading  growth
