【摘要】 以里格尔87-5、石红206、石红3号3个加工番茄品种为材料,对低温下其光合生理特性进行研究,旨在为加工番茄的高产栽培,品种选育和逆境鉴定方法提供理论基础。结果表明:加工番茄随着温度的降低,表现为Pn降低、Chl含量下降、MDA和可溶性蛋白含量升高,且均存在着品种间差异,具有较高Pn的里格尔87-5和石红206较石红3号对于低温逆境的适应性要强。更多还原

【Abstract】 The research was three tomatoes(Riegel 87-5,Shihong 206,Shihong 3) varieties’ physiological property under low temperature.In order to provide tomato’s theoretical principle of high-yield culture technique,varietiey selection,adversity identify method.The results indicated that the tomato’s Pn and the contents of tomato’s Chl was reduced,that MDA and dissolubility protein of tomato was raised with the temperature was reducing,at the same time between varieties was discrepancy,and Riegel 87-5 and Shihong 206 suitabilities were more powerful than Shihong 3.更多还原
