摘要
为了解盐胁迫条件下甜菜植株显微形态结构变化情况,以甜菜‘T510’为研究对象,研究280 mmol/L NaCl组与空白对照组在叶、叶柄及根的显微结构中的差异。结果表明:盐处理的叶片、茎及根部位的木质部和韧皮部相比空白对照组甜菜的木质部和韧皮部直径变小;盐处理叶片的气孔几乎都关闭,即使开放,开放程度也较小;盐处理的茎的薄壁细胞所占体积增大;盐处理根的表皮细胞壁加厚,并且根的薄壁组织中出现大量通气组织。
The paper aims to clarify the change of microstructure of sugarbeet under salt stress.In this study, seedlings of sugar beet ‘T510'were used for detecting the changes of microscopic morphology in leaves,leaf stalks and roots between control and NaCl treatment (280mmol/L NaCl).The resuhs showed that the diameter of xylemand phloem in leaves,leaf stalks and roots reduced after salt stress.The stoma was almost kept closed under salt stress without a handle of slightly opening ones.An increasing volume of stem parenchyma cell was also detected under salt stress.In roots,the thickening of epidermal cell wall and the formation of aerenchyma were found in response to salt stress.
