盐胁迫对鹅耳枥生长及生理生化特性的影响
Effects of salt stress on growth,physiological and biochemical characteristics of Carpinus turczaninowii seedlings
摘要
Abstract
To explore the responses of Carpinus turczaniowii to salt stress and its salt tolerance, we studied the growth, physiological and biochemical changes of two year old C. turczaninowii seedlings stressed with six gradients of NaCl con⁃centration( 0,1,2,3,4,5 g/L) . The results showed:① The growth of C. turczaninowii was inhibited by salt stress, be⁃cause the height growth,diameter growth,dry weight and relative water content of seedlings decreased with the increase of NaCl concentration. ②The protective enzymes ( SOD and POD) activity, soluble sugar content and soluble protein content was increased first and then decreased;③With the increase of salt stress, MDA content, relative conductivity and proline content increased, and reached a maximum under 5 g/L NaCl. We concluded that C. turczaninowii seedings can grow under low and moderate NaCl concentration ( 1-3 g/L) , but its growth was inhibited under 4-5 g/L NaCl. It indicated that C. turczaninowii seedlings has certain ability of salt tolerance,and they can be used widely in the land⁃scape.关键词
