摘要:
 以2年生黑果枸杞实生苗为材料,以不同浓度NaCl浓度胁迫,测定4个种源的黑果枸杞叶片生理指标的变化规律,采用隶属函数法分析不同种源黑果枸杞抗盐性强弱。结果表明,CAT和SOD的酶活性随着NaCl浓度的增加先上升后下降,POD的活性则呈下降趋势;随着NaCl浓度的升高,丙二醛含量呈增加趋势,游离脯氨酸含量呈增加趋势,可溶性糖含量呈上升趋势,可溶性蛋白质含量呈先增后降趋势;黑果枸杞叶片组织中的叶绿素a含量随着NaCl浓度增加总体上呈下降趋势,叶绿素b的含量在不同种源间变化趋势不一致。通过隶属函数值初步判断4个种源的黑果枸杞抗盐性由强到弱的顺序为民勤、瓜州、金塔和老寺庙。
Abstract:
 Two-year-old seedlings of Lycium ruthenicum from 4 different provenances were used to study the effects of different NaCl concentrations on the physiological parameters in the leaves.Different physiological parameters of L.ruthenicum seedlings treated with different NaCl concentrations were comprehensively evaluated by subordinate function values analysis.The results demonstrated that with the increase of NaCl concentrations,the activities of CAT and SOD increased firstly and then decreased,and the activity of POD decreased consistently.The contents of MDA,proline and soluble sugar increased,while the content of soluble protein increased firstly then decreased,accompanied with increasing NaCl concentrations.The contents of chlorophyll-a in L.ruthenicum leaves decreased generally by increasing NaCl stress,however,the change trends of the chlorophyll-b contents among different provenances were different.The comprehensive evaluation indicated the salt tolerance order of L.ruthenicum from 4 provenances was Minqin> Guazhou>Jinta>laosimiao.
