矮滨菊的耐荫性研究

Study on Shade Tolerance of Short Marina Chrysanthemum

为了研究矮滨菊的耐荫性,进行了30%、50%、70%、90%4个梯度的遮荫处理,以全光照处理作为对照,观察矮滨菊在4种处理下的形态指标、光合指标的变化。结果表明:矮滨菊在遮荫度为30%时形态的数值都要明显高于其他3个处理时的数值,50%时光合的数值要明显高于其他3个处理。因此认为矮滨菊具有一定的适应弱光环境的能力,在遮荫度为30%~50%的环境下生长良好。

In order to study the short marina chrysanthemum shade tolerance,30%, 50%, 70%, 90% 4 gradi- ent shading treatments were carried out, and the changes of morphological and photosynthetic indexes of dwarf Chrysanthemum under the 4 treatments were studied with full light treatment as control.The results showed that： when the shade was 30%, the value of morphology was significantly higher than that of the other 3 treatments, and the photosynthetically numerical data of 50% days was significantly higher than that of the other 3 treat- ments.It is concluded that the short marina chrysanthemum has a certain ability to adapt to the weak light envi- ronment and grows well in the shade of 30 to 50 percent shade.
