    摘要:

    通過(guò)盆栽試驗(yàn)，研究了水分脅迫及復(fù)水對(duì)水稻根冠功能的補(bǔ)償響應(yīng)。結(jié)果表明：水稻旱后復(fù)水根冠功能的補(bǔ)償效應(yīng)明顯，尤以分蘗末期短歷時(shí)重旱、拔節(jié)初期短歷時(shí)輕旱補(bǔ)償效應(yīng)最佳。旱后復(fù)水新生器官生理活性的提高是水稻產(chǎn)生補(bǔ)償效應(yīng)的主要貢獻(xiàn)者。

    Abstract:

    A research was carried out to determine the compensation effects of water stress and re-watering on the function of root shoot by pot experiments. The results show that the post-drought re-watering has obvious compensation effects to rice on the function of root shoot, which is particularly significant after short-duration heavy drought at the late tillering stage and light drought at the early jointing stage. Post-drought re-watering mainly embodies compensation effects in improving the physiological activity of neonatal crop organ. 
