This paper formally introduces the nutritional and biological characteristics of Mesembryanthemum crystallinum,and also summarizes its key cultivation techniques under the climatic conditions of North Zhejiang,including seed propagation, cuttage breeding,transplanting,field management,pest control, harvest,and seed preservation.展开更多
【目的】为了探明提高农林植物耐盐性途径和方法。【方法】对400 mM NaCl处理下的冰叶日中花幼苗,施用不同浓度硝普钠(SNP,外源NO供体,50、100、300、500、800μM),而后检测叶片H2O2、丙二醛(malondialdehyde,MDA)、可溶性糖和脯氨酸含...【目的】为了探明提高农林植物耐盐性途径和方法。【方法】对400 mM NaCl处理下的冰叶日中花幼苗,施用不同浓度硝普钠(SNP,外源NO供体,50、100、300、500、800μM),而后检测叶片H2O2、丙二醛(malondialdehyde,MDA)、可溶性糖和脯氨酸含量,以及过氧化物酶(peroxidase,POD)、超氧化物歧化酶(superoxide dismutase,SOD)、过氧化氢酶(catalase,CAT)和抗坏血酸过氧化物酶(ascorbate peroxidase,APX)活性。【结果】结果表明,外源SNP提高了盐胁迫下抗氧化酶活性,促进了可溶性糖和脯氨酸的积累,降低了H2O2和丙二醛含量,显著提高了冰叶日中花的耐盐性。【结论】由此可见,NO在冰叶日中花对盐胁迫的生理响应中可能起着重要的信号调控作用。展开更多
