Abstract
Six low-molecular organic acids and one organic potassium were sprayed on foliage of pepper plants in pot experiment,and their effects on plant growth,nutrient uptake,yield and fruit quality of hot pepper were investigated.The results showed that organic acids spray increased plant height and stem diameter,reduced root dry mass,promoting the growth of aboveground plants.But organic acids spray had no significant impacts on the uptake of N,P,K in soil,and decreased the distribution rates of N,P in fruits.Formic acid,levulinic acid and potassium levulinate treatments significantly enhanced pepper yield,and potassium levulinate treatment got the highest yield(99.5 g/plant),followed by levulinic acid(98.2 g/plant).The impacts of organic acids spray on total fruit number,red fruit number,single fruit mass,single fruit dry mass and fruit shape index were insignificant.Acetic acid,propionic acid and citric acid treatments significantly increased edible part of hot peppers.Oxalic acid treatment significantly increased soluble sugar content and reduced crude fiber content in pepper fruits.Levulinic acid and potassium levulinate treatments significantly increased the contents of starch and vitamin C in pepper fruits,and the color value unite of hot pepper.Comprehensive analysis indicates that potassium levulinate spray had the best effects on improving yield and quality of hot pepper.
