盐胁迫下8个转基因小黑杨株系的抗逆性比较
Adverse Resistance Comparison of Eight Transgenic Populus simonii ×P. nigra Lines under NaCl Stress
摘要
Abstract
Eight transgenic lines were selected from three kinds of transgenic Populus simonii ×P. nigra obtained before,including XC1, XB, XB2, XB3, XL1, XL5, XL6 and XL11, while non-transgenic ones were used as control. Treating them with 0.8% NaCl, the chlorophyll content and other main phsiological indicators were measured respectively on 6th day after stress. The results illustrated that the average chlorophyll content in transformants were 7.9% higher than that in the non-transformants. The activity of POD, CAT and APX was higher than the control while the damage degree of membrane in transformants was lower than the control. The activity of SOD in XL1, XL5, XL6 and XB4 were higher than the control. As a whole, the transformants had less injury degree of membrane and stronger anti-oxidative ability than the control.关键词
