摘要: 研究结果表明: 番茄不同生育阶段耐弱光性不同, 弱光下番茄苗期表现为徒长趋势, 叶干样
质量/ 叶面积与叶面积/ 全株干样质量上升, 叶绿素含量、叶绿素b/ a 值和坐果率增加, 可溶性糖和可溶性蛋白含量下降; 与苗期相比, 开花坐果期POD 酶活性和可溶性蛋白含量增加, 坐果率下降。

Abstract: In the experiment, the morphological and physiological changes of tomato at different growth stages under low light were studied. The results showed that the tomato seedlings had a tendency of overgrowing under low
light. Low light at seedling stage led to the increase of SLW, LAR, Chlorophyll Content, Chlorophyll b/ a value and percentage of fruit setting and the decrease of soluble sugar and protein content. While the low light at
blooming and setting stage led to the increase of POD activity and soluble sugar content and the decrease of the percentage of fruit settings, comparing with that at seedling stage.

Key words: Tomato, Low light, Growth stages, Morphological, Physiological index
