鱼蛋白水解物对番茄幼苗生长及光合特性的影响
Effects of fish protein hydrolysate on the growth and photosynthetic characteristics of tomato seedlings
摘要
Abstract
In order to study the effects of fish protein hydrolysate on the growth and photosynthetic characteristics of tomato seedlings,CR(Solanum lycopersicum var.Cerasiforme)variety was used as experimental material,and five different concentrations of fish protein hydrolysate treatments were set up in this study.The plant height,root length,biomass,root activity,nutritional index,antioxidant enzyme activity,photosynthetic index,chlorophyll content and chlorophyll fluorescence parameters of tomato seedlings were measured to determine the appropriate concentration of fish protein hydrolysate for the growth of tomato seedlings.The results showed that compared with the control,T1,T2,T3 and T4 treatments(fish protein hydrolysate diluted 2000,1600,1200,800 times)promoted the growth of tomato seedlings,and T3 treatment(diluted 1200 times)had the best effect on the growth of tomato seedlings,with its plant height,stem diameter,root length,aboveground fresh weight,underground fresh weight,and root vitality were significantly(p＜0.05)higher than those in other treatment groups and control.Compared with the control,the content of soluble sugar and soluble protein also significantly increased.In the T3 treatment,the activities of POD and SOD were significantly increased,the MDA content was significantly decreased,and the ability of antioxidant and stress resistance was enhanced.Compared with the control,total chlorophyll content and photosynthetic rate of tomato seedlings in T3 treatment were increased by 22.16%and 23.57%,respectively.At the same time,it was found that T3 treatment significantly improved the PSⅡ maximum photochemical efficiency(Fv/Fm),the actual photochemical efficiency(ΦPSⅡ)and the non-photochemical quenching coefficient(NPQ)of tomato seedlings.Therefore,diluting 1 200 times the fish protein hydrolysate treatment can significantly promote the growth of tomato seedlings and enhance plant photosynthetic characteristics.This study provides an efficient and sustainable fertiliza-tion method for tomato seedling cultivation,which has application value and popularization prospect,and provides a theoretical basis for the application of fish protein hydrolysate in vegetable seedling cultivation.关键词
