盐胁迫对水稻根系相关性状及产量的影响
|
摘要
以寒地粳稻牡丹江30(MDJ30)与龙稻5(LD5)为材料,分析不同浓度盐胁迫处理对水稻根系形态特征、根系活力、根干重、根冠比及产量的影响。结果表明:与对照相比,盐胁迫下根长、根表面积、根体积、根系活力、根干重均显著下降,且随盐浓度增加下降幅度不断增大。相同盐胁迫处理,耐盐品种LD5的相对根长、相对根表面积、相对根体积、相对根系活力、相对根干重均大于盐敏感品种MDJ30。与对照相比,盐胁迫下根冠比不断下降,且灌浆期S4处理的根冠比显著下降。盐胁迫下,两品种产量均下降,相同盐胁迫下,两品种产量差异显著。相关分析结果表明,各生育时期的根系相关性状与产量均呈极显著正相关,盐胁迫下根系生长受抑制不利于产量的形成。
The effects of different concentrations of salt stress treatment on rice root morphological characteristics, root activity, root dry weight, root-shoot ratio and yield were analyzed using japonica rice Mudanjiang 30(MDJ30) and Longdao 5(LD5) as materials in cold region. Results showed that compared with the control, under salt stress, root length, root surface area, root volume, root activity and root dry weight all decreased significantly, and the decreasing range increased with the increase of salt concentration. Under the same salt stress treatment, the relative root length, relative root surface area, relative root volume, relative root activity and relative root dry weight of salt-tolerant variety LD5 were all larger than that of salt-sensitive variety MDJ30. Compared with the control, the root-shoot ratio under salt stress decreased continuously and the root-shoot ratio under S4 treatment decreased significantly during filling stage. Under salt stress, the yield of the two varieties decreased. Under the same salt stress, the yield difference between the two varieties was significantly. Correlation analysis showed that root-related traits at all growth stages were significantly positively correlated with yield. The inhibition of root growth under salt stress was adverse to the yield formation.
