摘要: 本研究结果表明,旱育秧苗移栽大田后仍能保持较强的生理生化优势,从分蘖期到乳熟期,旱育秧植株的抗坏血酸氧化酶、超氧化物歧化酶、过氧化物酶、过氧化氢酶、ATP酶和硝酸还原酶活性分别比对照高4.09~12.22%、8.22~19.68%、10.19~24.73%、2.77~22.36%、36.11~137.5%和26.11~135.2%, 丙二醛含量降低5.04~7.14%, 膜透性相应减少29~16.06%, 因而抗逆性强,秧苗移栽后返青快、分蘖早、成穗率高,叶片不早衰,干物质积累多,高产。

Abstract: The study shows that after transplantation, the dry-raising seedlings still kept high physiobiochemical vigor.From tillering to milky stage, the dry-raising plants had higher activities of ascorbate oxidase, superoxide dismutase, peroxidase, catalase, ATPase and nitrate reductase, but lower content of malondialdehyde and lower membrane permeability than the wet raising plants, indicating that dry-raising plants had a strong adversity-resistance, and thereby, they could turn green fast, tiller early, have a high productive tiller rate, keep their leaves to grow for a longer period of time, and have more dry matter accumulation and high yield.
