干旱胁迫对5个金银花品种生理生化特征的影响
Effects of drought stress on physiological and biochemical characteristics of five honeysuckle varieties
摘要
Abstract
Honeysuckle has good medicinal value and health care function.In order to screen honeysuckle varieties suitable for planting in pressed sandy land in Ningxia,five moisture gradients of 21.93%,15.47%,10.31%,6.45%and 3.87%were set based on the field water holding capacity of selenium honeysuckle planting area in Xingren Town,Shapotou District,Zhongwei City.The antioxidant enzyme activity,osmoregulatory substance content and drought tol-erance of leaves of four season honeysuckle,red honeysuckle,Beiflora No.1 honeysuckle,Jiufeng No.1 honeysuckle and Pingyi Shanhuazi honeysuckle were investigated under the five moisture gradients.The results showed that the su-peroxide dismutase(SOD)activity,peroxidase(POD)activity,catalase(CAT)activity,malondialdehyde(MDA)content,proline(Pro)and soluble protein(SP)content of five honeysuckle varieties increased with the increase of drought stress.Correlation analysis showed that drought stress was significantly positively correlated with various physio-logical indexes.According to the comprehensive evaluation of the membership function,the drought resistance ability was Pingyi Shanhuazi honeysuckle>red honeysuckle>Beiflora No.1 honeysuckle>four season honeysuckle>Ji-ufeng No.1 honeysuckle.In summary,Pingyi Shanhuazi honeysuckle,red honeysuckle and Beiflora No.1 honeysuckle can be used as drought-resistant varieties of honeysuckle in Ningxia pressed sandy land.Our results provide a theoretical basis and practical guidance for the selection of honeysuckle varieties in pressed sandy land in Ningxia.关键词
