MeJA浸种对干旱胁迫下玉米种子萌发及幼苗生理特性的影响OA北大核心CSCDCSTPCD
Effects of Seed Soaking with MeJA on Seed Germination and Seeding Physiological Characteristics of Maize under Drought Stress
为探讨茉莉酸甲酯(MeJA)调节玉米幼苗生长、提高幼苗抗旱性的机制,采用PEG-6000处理模拟干旱胁迫,研究了不同浓度外源MeJA浸种对干旱胁迫下玉米种子萌发及幼苗生理特性的影响.结果表明,干旱胁迫显著抑制玉米种子萌发和幼苗生长,低浓度MeJA浸种则能缓解干旱胁迫造成的伤害.干旱胁迫使玉米种子发芽率和发芽势比清水对照分别降低48.1％和54.6％,0.25 μmoL/L MeJA处理的种子发芽率和发芽势则比干旱胁迫分别增加66.3％和93.2％…查看全部>>
To investigate the mechanism of MeJA to regulate the growth and improve the drought resistance of maize seedlings,the effects of exogenous MeJA with various concentrations on seed germination and seedling physiological characteristics under PEG-6000 simulated drought stress were studied.The results showed that drought stress significantly inhibited seed germination and seeding growth in maize,and seed soaking with low-concentration of MeJA could alleviate th…查看全部>>
