不同浓度调环酸钙对大葱幼苗生长的影响
Effects of Different Concentrations of Prohexadione Calcium on the Growth of Green Onion Seedlings
摘要
Abstract
The green onion variety'Dongsenhancong No.2'was used as experimental material,and the effects of different concentrations of prohexadione calcium(Pro-Ca,200,400,600,800 mg·L-1)on the quality of green onion seedlings were investigated by measuring the morphological index,chlorophyll content and root activity at seedling stages.The results showed that Pro-Ca could effectively increase the pseudostem diameter,pseudostem length and chlorophyll content of green onion seedlings leaves,enhance root activities,promote root growth,and the appropriate concentration of Pro-Ca was 600 mg·L-1.Compared with water control treatment,the pseudostem diameter,pseudostem length and root activity of green onion seedlings treated with 600 mg·L-1 Pro-Ca were increased by 22.0%,66.9%and 65.7%,respectively,while the root,pseudostem,leaves and whole plant dry weight were increased by 38.5%,48.4%,34.6%and 37.9%,respectively,at 21 days after treatment.The root shoot ratio,seedling index and total chlorophyll content under 600 mg·L-1 Pro-Ca treatment were increased by 23.0%,37.0%and 19.4%in comparison to 200 mg·L-1 chlormequat chloride(CCC)treatment.In conclusion,the quality of green onion seedlings can be improved by spraying 600 mg·L-1 of Pro-Ca on the leaf surface at seedling stage.关键词
