摘要:

以新两优6号为材料,采用盆栽试验,研究了不同生育阶段干旱胁迫历时对水稻生长、生理指标和产量的影响。结果表明,干旱处理使水稻株高得到抑制,抗倒伏能力提高;使叶片MDA浓度、脯氨酸含量和可溶性糖含量明显增加,随着干旱历时增加,先是急速增加,而后下降;分蘖期短时间干旱胁迫(T1)未造成新两优6号减产,产量反而增加9.2%。

Abstract:

Using rice variety Xinliangyou 6 as materials, the effects of water stress on growth, physiological characteristics and yield of rice were studied. The results indicated that the plant height were decreased, the crop-stem lodging resistance was effectively increased, the content of Methane Dicarboxylic Aldehyde and proline and total soluble sugar were markedly increased. Compared with CK, the yield of the short time water stress treatment (T1) was increased by 9.2%.

Key words: rice, water stress, tillering stage, booting stage, yield
