Different waterlogging tolerances of nine rapeseed ( brassica napus l . ) genotypes were investigated after germinating seed anoxic stress for 12h and spring field waterlogging for l0d 摘要9个不同遗传背景的甘蓝型油菜品种（系）在室内进行发芽种子水淹和春季田间模拟湿害条件下，研究油菜对湿害胁迫的耐湿遗传差异。
Many diverse species of plants accumulate glycine betaine ( glybetaine ) in response to various stresses , and the biosynthesis and accumulation of glybetaine are thought to contribute to various stress 许多植物在受到各种胁迫时，都会引起甘氨酸甜菜碱的积累，甘氨酸甜菜碱的生物合成与积累是植物对胁迫的一种适应机制。
Therefore , one important strategy for plants to survive under salt stress is to re - establish the homeostasis in high salt environment . both ionic and osmotic homeostasis must be restored 因而植物对抗盐胁迫的一个重要策略是在高盐环境下重建体内的稳态( homeostasis ) ，包括重建离子稳态( ionichomeostasis )和渗透稳态( osmotichomeostasis ) 。
Water stress induce the high and quick accumulation of plant hormone abscisic aicd ( aba ) , which reduce the stomatal conductance of leaves , decrease the loss of water , and improve plant tolerance to water stress 渗透胁迫可以诱导植物积累脱落酸( aba ) ， aba的积累可以降低植株叶片气孔导度，减少水分的散失，从而增强植物对渗透胁迫的适应性。
Previously , we haved identified that ssmapkk was induced in stems by salt stress . then the ssvp orf was integrated into the plant expression vector pcambia1300 and ssmapkk orf was integrated into the plant expression vector prokii 以前的实验已证明ssmapkk的转录水平受盐胁迫的诱导，由此推测ssvp和ssmapkk都与盐地碱蓬对盐的反应有关。
The goals are to elucidate the plant signaling pathways in response to environmental stresses and to identify key components that can potentially be engineered for improvement of crop plants to encounter environmental stresses 目的是为了阐明植物响应环境胁迫的信号路径，并鉴定一些具有潜在功能的能够提高作物适应环境胁迫的关键作用元件。
In order to elucidate the mechanism how plant to perceive the water stress , suspension cultured system of tobacco cell was established in the experiment and the mechanism how tobacco cells perceive the mannitol tress was studied 为阐明植物对渗透胁迫的感受机制，本实验建立了烟草细胞悬浮培养体系，研究了悬浮培养的烟草细胞对甘露醇胁迫诱导积累aba及其感受机制。
Phytohormones are important regulators of growth and development in stress . in this paper , phytohormones regulate phant growth and phytohormones molecules transduct signal pathway in salt - stress were reviewed in recent stages 摘要在逆境条件下，植物激素对植物生长发育有重要的调控作用。本文主要就近年来植物激素对植物盐胁迫的调控及盐胁迫下激素分子的信号转导所取得的研究进展作一简要概述。
Northern blot suggested that the transcription of nramp gene is induced by iron stress in both roots and leaves and strengthened by iron stress in leaves ; the transcription of irt gene can be induced and strengthened by iron stress in roots Northern杂交结果表明：在根中和叶中， nramp基因均能得以转录且受缺铁胁迫的诱导而加强。 fe ( ) -转运蛋白基因在根中的转录也受到缺铁胁迫的诱导，并随缺铁胁迫处理天数的增加而加强。
