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。
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.
