Ca(NO_3)_2对黄瓜幼苗生长及光合色素含量的影响

Effect of Ca(NO_3)_2 on Growth and Development and Photosynthetic Pigment Content of Cucumber Seedlings

对Ca(NO_3)_2·4H_2O对黄瓜幼苗生长及光合色素含量的影响进行了研究,结果表明:Ca (NO3)2·4H2O施用量增加时,黄瓜株高和叶面积下降,叶片光合色素含量先下降后上升.黄瓜中部叶光合色素含量最高,基部叶最低.

Effect of Ca（NO3）2·4H2O on growth and development and photosynthetic pigmentcontent of cucumber seedlings were studied. The results showed that, the plant height and leaf area decreased, the content of photosynthetic pigment increased firstly and then decreased when Ca（NO3）2·4H2O increased. Photosynthetic pigment content was the highest in the middle leaf and lowest in the basic leaf.
