摘要
为了探究LaCl3对干旱胁迫下水稻幼苗生长及生理特性的影响, 采用15% PEG6000模拟干旱胁迫, 研究不同浓度LaCl3对干旱胁迫下水稻幼苗生物量、壮苗指数、根系形态、抗氧化系统、丙二醛含量等的影响。研究结果表明, 喷施外源LaCl3后, 干旱胁迫下水稻幼苗的各项指标呈现低促高抑的浓度效应, 其中, 1 μmol/L的LaCl3可以显著促进植株鲜重及地上部分干重; 100 μmol/L的LaCl3可以显著提高地下干重和壮苗指数、叶片和根系SOD活性、叶片CAT活性, 降低根系MDA含量。本研究为LaCl3调控水稻幼苗耐旱机制研究奠定了基础。
Abstract
In order to investigate the effects of LaCl3 on the growth and physiological characteristics of rice seedlings under drought stress, 15% PEG6000 was used to simulate drought stress. The effects of different concentrations of LaCl3 on the biomass, seedling index, root morphology, antioxidant system and malondialdehyde content of rice seedlings under drought stress were studied. The results showed that after spraying exogenous LaCl3, the indexes of rice seedlings under drought stress showed a concentration effect of low promoting and high suppression. 1 μmol/L LaCl3 can significantly promote the fresh weight of plants and the dry weight of aerial parts. 100 μmol/L LaCl3 can significantly increase the underground dry weight and seedling index, SOD activity of leaves and roots, CAT activity of leaves, and decrease of MDA content in roots. This study laid the foundation for the study of LaCl3 regulation of drought tolerance in rice seedlings.
