摘要
研究了30℃和35℃昼间亚高温条件下,番茄植株光合产物生产及各器官干物质积累与分配的变化情况。结果表明: 30℃和35℃昼间亚高温可促使番茄叶绿素含量减少,光合作用下降,植株干物质总量降低,植株生长发育受到影响;同时光合产物向植株根系和叶片分配减少,而向果实分配增加,果实发育提早,生育期缩短。
The effects of different temperature during daytime(25 ℃, 30 ℃, 35 ℃)on photosynthesis and carbon accumulation and distribution of tomato in greenhouse were studied. The results showed as follows, sub-high temperature decreased the chlorophyll and photosynthesis of tomato and made the growth of plant worse than control. Sub-high temperature advanced the development of fruits, and shorted the time of maturation. The carbon accumulation and distribution of tomato under sub-high temperature were changed as well.
