Abstract:

In response to the insufficient research on drought resistance in honeysuckle and the unclear patterns of change in its main medicinal components under arid conditions,this study investigated the effects of different water stress levels on key medicinal indicators across various honeysuckle germplasms. The contents of chlorogenic acid,neochlorogenic acid,isochlorogenic acid A,isochlorogenic acid C,lonicerin,luteoloside,secologanoside,and secologanic acid were measured in five honeysuckle varieties under different drought treatments. Comprehensive evaluation using two-way analysis of variance,one-way analysis of variance,correlation analysis,and principal component analysis revealed that variety and water stress are key factors affecting the content of medicinal components in honeysuckle. The metabolism of these components exhibits interdependent,promoting,or inhibiting relationships. Except for the atypical performance of Jiufengyihao honeysuckle,the medicinal component contents in Siji honeysuckle,Hongse honeysuckle,Pingyishanhuazi honeysuckle,and Beihuayihao honeysuckle consistently decreased with increasing drought severity. Under the five drought stress levels,Hongse honeysuckle performed the best,while Jiufengyihao honeysuckle consistently received the lowest scores. Through systematic analysis and evaluation of the main medicinal components in these five varieties,this study provides a theoretical basis for understanding the changing patterns of medicinal components in honeysuckle under drought stress and for breeding drought-tolerant superior varieties.
