摘  要:
通过测定高温处理后水培和土培樱桃番茄的几项生理指标,研究了樱桃番茄在高温胁迫条件下的叶水势、光合速率、SOD酶活性等生理指标的变化特征,结果表明,高温胁迫条件下土培番茄叶水势、光合速率和SOD活性大幅度下降,而水培番茄上述生理指标虽有下降,但幅度远较土培番茄为少,因此,水培樱桃番茄对高温的抵抗能力要强于土培。

摘  要:
The influence of high temperature stress on several physiological indices of cherry tomato in NFT and in soil was studied in this paper.The variation of physiological indices,including leaf water potential,photosynthetic rate and superoxide dismutase of cherry tomato under high temperature stress was measured.The results showed that the physiological indices above mentioned decreased dramatically when the plants were planted in soil under high temperature condition,while only a slight decrease was found from the plants planted in NFT.It can be concluded that the heat resistance of tomato seeding under NFT was stronger than that under soil culture.
