| 摘 要： | 从遮光(遮光率64.75%、86.87%分别记为一层处理、两层处理)对10个不同生物学特性的番茄品种生理特性的影响方面进行了研究。结果表明,10个品种的一层处理叶绿素a、叶绿素b、叶绿素总量、叶绿素a/b与对照相比变化不一致;两层处理变化规律一致,即:叶绿素a、叶绿素b、叶绿素总量与对照相比增加,叶绿素a/b值降低。遮光处理后,番茄各品种可溶性糖含量、干物质含量降低,并且随着遮光程度的加大,二者的降低幅度加大,可溶性糖含量、干物质含量之间存在极显著的正相关关系。

| Abstract: | The effects of weak-light(weak-light ratio 64.75%,86.87% marked with 1-layer-dealed and 2-layer-dealed) on 10 kinds of tomato's physiologic characters are studied.The results of variance show differences in Chla,chlb,chlorophyll contents and chla/b between 1-layer-dealed and formal samples.Meanwhile,the 2-layer-dealed goes the same way with samples.The weak-lighted tomato goes down with the content of soluble sugar and dry weight,and they go deeper while the weak-light ratio goes up.The correlation coefficient between content of soluble sugar,dry weight and weak-light ratio is opposite. |

| Keywords: | weak-light chlorophyll soluble sugar dry weight correlation coefficient |
