不同外源物质对盐、碱及干旱胁迫下草木樨种子萌发、幼苗生长及生理的影响OA北大核心CSTPCD
Effects of different exogenous substances on the seed germination,seedling growth,and physiology of Melilotus suaveolens under salt,alkali,and drought stress
为筛选出促进盐、碱及干旱胁迫下草木樨种子萌发和幼苗生长的最佳外源物质及其处理浓度,采用培养皿滤纸发芽法,研究不同浓度赤霉素(GA)和褪黑素(MT)浸种6 h对盐、碱及干旱胁迫下草木樨种子萌发及幼苗生长的影响.结果表明,盐胁迫下,200 mg·L-1的GA是促进种子萌发的最佳处理,50μmol·L-1的MT是提高幼苗超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)活性的最佳处理.在碱胁迫下,200μmol·L-1的MT则使幼苗胚…查看全部>>
The aim of this study was to determine the best exogenous substance,and its optimal concentration,to promote the seed germination and seedling growth of Melilotus suaveolens under salt,alkali,and drought stress.Seeds of M.suaveolens were germinated in Petri dishes on filter paper with gibberellin (GA) and melatonin (MT) at various concentrations.The effects of these substances on the seed germination and seedling growth of M.suaveolens,as well its responses …查看全部>>
