- 摘要:
- 以5 a生骏枣和灰枣为试材,研究了不同浓度NaCl胁迫处理对枣树叶片色素含量、可溶性糖含量、可溶性蛋白质含量、游离脯氨酸(Pro)含量、丙二醛(MDA)含量等生理指标的影响,以期为新疆盐渍化土壤栽培红枣及枣树耐盐育种提供理论依据。结果表明:随NaCl浓度的升高,骏枣和灰枣的叶绿素含量先增加后下降;灰枣的可溶性糖含量随NaCl浓度的增高而增加,骏枣可溶性糖含量随NaCl浓度的增高而减少;灰枣和骏枣的丙二醛含量均随NaCl浓度的增高而增加;骏枣的可溶性蛋白质含量随NaCl浓度的增高而增加,灰枣的可溶性蛋白质含量随NaCl浓度的增高而下降;灰枣和骏枣的游离脯氨酸含量均随NaCl浓度的增高而下降。综合分析表明,灰枣的耐盐性大于骏枣。
- Abstract:
- With five years Ziziphus jujubea cv.Huizao and Ziziphus jujubea cv.Junzao as test materials,several physiological indices,such as chlorophyll contents,soluble sugar contents,soluble protein contents,proline contents and malondialdehyde(MDA)contents of leaves under different concentration of salt stress simulated by NaCl were studied,in order to provide theoretical basis for cultivating jujube in salinity soil and breeding for salinity tolerance jujube in Xinjiang.The results showed that with the increase of salt concentration,the chlorophyll contents increased initially and then decreased;the soluble sugar contents of Huizao increased gradually while Junzao decreased gradually;the MDA contents of Junzao and Huizao increased gradually;the soluble protein contents of Junzao increased gradually while Huizao decreased gradually;the proline contents of Junzao and huizao decreased gradually.Comprehensive analysis showed that Huizao showed better in salt-tolerance ability than Junzao.
