摘要
研究2h、4h、6h和8h昼温35℃的亚高温处理对番茄光合作用的影响。结果表明:4h植株叶片净光合速率(Pn)的日变化明显高于对照;2h和4h番茄叶片Pn下降主要是气孔限制因素引起的,而6h和8h植株叶片Pn下降主要是由非气孔限制因素引起的。
The paper investigates the effect of short time suh-high temperature on photosynthesis of tomato. The results showed that diurnal change of tomato leaves＇ net photosynthetic rate in 4 h was higher than control, and leaves＇ net photosynthetic rate in 2 h and 4 h was reduced hy stomata limitation, however, leaves＇ net photosynthetic rate in 6 h and 8 h was reduced hy non-stomata limitation.
