药用作物茬口对当归苗栽生理生化特性的影响
Effects of Medicinal Crop Stubbles on Physiological and Biochemical Characteristics of Angelica sinensis Seedlings
摘要
Abstract
Objective:To screen suitable cultivated field soil for nursing Angelica sinensis seedlings to replace the traditional seedling cultured in wild virgin land.Methods:Using the abandon soil as the control,the root viability,the content of soluble protein,relative conductivity,amino acid leak rate,malondialdehyde content and anti-oxidant enzyme activities in Angelica sinensis seedling roots under different stubble soil conditions(Angelica sinensis stubbles,Gentiana macrophylla stubbles,Notopterygium incisum stubbles)were determined and analyzed.Results:There were significant effects of different medicinal crops on the roots viability,osmotic adjustment substance contents,cell membrane stabilities,membrane lipid peroxidation and anti-oxidant enzymatic activities of the plant seedlings.The cell enzyme antioxidant systems of the roots was weak,and resulting in lower osmotic adjustment materials,higher membrane lipid peroxidation,reduction of plasma membrane stabilitiess in the Angelica sinensis seedlings cultivated from Angelica sinensis stubbles and Notopterygium incisum stubbles soils lead to the morbidities sharply increases after through the winter.There were no significant differences in physiological and biochemical indicators of the Angelica sinensis seedling roots on Gentiana macrophylla stubbles soil compared with the control,of which roots on the soil conditions with developed anti-oxidation systems,small degree of membrane lipid peroxidation,good stability in membrane,balanced osmotic adjustment materials and strong activities of roots,resulted in a low incidence through the winter.Conclusion:Gentiana macrophylla stubbles soils can be used for Angelica sinensis seedling cultivation with high resistance to stress.关键词
