- Abstract
【Objective】 To explore medical plant resources, develop new pesticides, and promote green agricultural production, the regulatory effects of methanol extracts of 16 common medical plants on wheat germination and seedling growth were investigated, and new plant source extracts with good growth regulation activity were screened out and the appropriate concentration range was determined. 【Methods】 16 kinds of agricultural medicinal plant methanol extract were prepared into four different concentrations (10%, 1%, 0.1%, 0.01%) of the solution. Through germination test screening and potting test verification, the leaf length, stem thickness, dry and fresh weight of aboveground parts, endogenous hormone content and photosynthetic characteristics of wheat seedlings were determined, and the plant-derived extracts with the best effect were evaluated by the membership function method and principal component analysis method and after that the appropriate concentration range was determined. 【Results】 The results showed that the germination potential of 0.01%Sophraalopecuroides, Vallisnerianatans and Cuminumcyminum methanol extracts increased by 10.00%, 8.83% and 7.62%, respectively, and the root length increased by 23.44%, 21.88% and 18.75%, respectively. The comprehensive evaluation of seed germination experiments by membership function method was preliminarily screened out, 0.1% Sophraalopecuroides, 0.01% Sophraalopecuroides, 0.01% Cuminumcyminum, 1% Vallisnerianatans, 0.1%Vallisnerianatans, 0.01% Vallisnerianatans, 10% DaturametelL and 0.01% Euphorbia pekinensis extract, and further potting experiments verified that the leaf length of 0.01% Sophraalopecuroides and Vallisnerianatans extract increased by 16.62% and 15.91%, respectively, and the fresh weight of wheat treated with Cuminumcyminum and Sophraalopecuroides extract increased by 14.78% and 5.15%, respectively. The indexes were comprehensively sorted by principal component analysis, and the top three evaluation scores were 0.01%Sophraalopecuroides, 0.01%Vallisnerianatans and 0.01% Cuminumcyminum extract, which had certain growth promotion potential for wheat. 【Conclusion】 The three concentrations of methanol extracts of 0.01% Sophraalopecuroides, 0.01% Vallisnerianatansand 0.01% Cuminumcyminum have good effects, which can regulate the endogenous hormone level of wheat and promote the growth of seedlings.
