乙烯利对苦玄参生长的影响
Effects of ethrel on growth of Picria fel-terrae Lour.
摘要
Abstract
[Objective]The effects of ethrel on seed germination,seeding breeding,growth and accumulation of glycosides in Picria fel-terrae Lour.were studied to provide references for artificial cultivation and relevant research of Picrra fel-terrae Lour.[Method]With clear water as the control,soaking seed and foliar application at three concentrations of ethrel (25,50,75 mg/L) were conducted to research the effects of ethrel on the growth of Picira fel-terrae Lour.[Result]The seed germination was promoted by soaking seed with 50-75 mg/L ethrel,and the seedling stem diameter,root diameter,leaf area,fresh weight per plant,lateral root number and percentage of seedling were increased by 50-75 mg/L ethrel.The stem diameter of plant,level 3 branch,number of blades and biomass production were increased by 25-75 mg/L ethrel,but ethrel did not obviously influence the development progress of plant and the accumulation of glycosides.[Conclusion]Soaking seed and foliar application at optimal concentration of ethrel could promote seed germination and seedling growth,which led to a high percentage of seedling.Foliar application at optimal concentration of ethrel could markedly facilitate the growth of plant and consequently increase the biomass production of Picira fel-terrae Lour.关键词
