摘要
脯氮酸积累同植物的抗旱性有密切关系。评价植物间抗旱性的大小有两个指标,即脯氨酸维持积累时间和脯氨酸维持积累量。在脯氨酸维持积累时间和维持积累量的概念下,水分胁迫导致的脯氨酸积累可以作为鉴定短芒披碱草和老芒麦幼苗的抗旱性生理指标。
According to our experimental results, there were cloce relation between free proline accumulation and drought resistance of plants. There were two indexes in comparing size of drought resistance in plance, namely, 'time of proline maintaining accumulation' and 'amount of proline maintaining accumulation'. Free proline accumulation can be utilizaed as positive index in comparing seedlings of Elymus breciristatus and E. sibiricus in drought resistance under the concept of 'time of proline maintaining accumulation' and 'amount of proline maintaining accumulation'.
