不同铵硝配比对低温胁迫棉花幼苗生长及抗氧化酶活性的影响OA北大核心CSCDCSTPCD
Impacts of different ammonium/nitrate ratios on the growth and antioxidant defense enzyme activities in cotton seedlings exposed to low-temperature stress
[目的]新疆春季的“倒春寒”是严重阻碍棉花前期的生长发育,影响产量及品质的主要非生物限制因子之一,而氮素供应及氮素形态对棉花(Gossypium hirsutum)的生长发育具有显著影响.研究低温胁迫下不同铵硝配比对棉花幼苗抗氧化酶活性及质膜脂质过氧化伤害的影响,为通过调节氮素供应提高棉花抗寒性提供理论依据. [方法]以‘新陆早13号’为供试棉花品种,在人工气候室内采用营养液水培法调节铵硝营养配比,研究了常温和低温条件下,不同铵硝配比对低温胁迫下…查看全部>>
[Objectives] Frequently occurred low-temperature in early spring is one of the major abiotic stresses severely restricting the growth,yield and quality of cotton (Gossypium hirsutum) in Xinjiang,China.Nitrogen supply has been proved to play significant role in regulating the resistance of crops to abiotic stress.Studying the impacts of different ratios of NH4+/NO3 supply on the physiological process of cotton will provide a theoretical base to alleviate the …查看全部>>
