富氢水处理对铜胁迫下小麦幼苗生长及其细胞结构的影响
Effects of hydrogen-enriched water on growth and cell structure of wheat seedlings under copper stress
摘要
Abstract
At the present study using wheat cultivar " Lin 8161 " as a material which was cultured in different concentration of Cu2+ is to explore the effects of hydrogen enriched water on seed germination and seedling growth.The morphology of root tip cells and the development of root were observed.The morphology and distribution of stoma in leave were compared.The results showed that with a increase of Cu2+ concentration,the seed germination and growth of root tip as well as seedling height were inhibited significantly.Higher concentration of Cu2+ damaged the integrity of the cell membrane of roots and caused nuclear structure irregular,the stomatal diameter was decreased as well.Hydrogen-rich water somehow alleviated a negative effects of Cu2+ on wheat seedlings where the damage of root cells and nucleus were decreased,the leaf stomatal diameter was bigger and more regular.It indicated that hydrogenrich water could reduce the effects of Cu2+ on wheat root and seedling development.关键词
