摘要
以吉林珲春,山东牟平,山东荣成3个地理种源的野生玫瑰为材料进行盆栽试验,研究了干旱胁迫下玫瑰的生理生化变化与抗旱性强弱。结果表明,干旱胁迫条件下,3个种源野生玫瑰的5个抗旱生理生化指标的变化趋势基本一致,但各指标的变化程度因种源不同而异。通过"坐标综合评定方法"对5个生理生化指标进行综合评定,得到3个种源野生玫瑰的抗旱性强弱等级依次为吉林珲春,山东牟平,山东荣成。
The relationship between physiological-biochemical changes and drought resistance of different wildness Rose provenances were studied. The provenances were selated from Jilin Huicun, Shandong Muping, Shandong Rongchen. The results showed that the tendency of the physiological and biochemical indexes in three provenances under drought stress were similar. And the change degree of the indexes was different due to different sources of provenances. Through coordinate composite evaluation on 5 physiological and biochemical indexes, the results indicated that drought-resistance sequence of three provenances were Jilin Huicun, Shandong Muping, Shandong Rongchen.
