高硫代葡萄糖苷油菜种子对蔬菜土传病害病原菌的抑制效果
Inhibitory Effects of High Glucosinolate Rape Seeds on Pathogens Causing Vegetable Soil-borne Diseases
摘要
Abstract
To screen biofumigation materials suitable for soil disinfection in the green control of crop soil-borne diseases,seeds of 7 rape varieties or lines,namely Long12PZ16-65,16QP-65,Longyou 7,Longyou 8,R0162,R0153,and R0157,were select-ed as experimental materials.The glucosinolate content of the seeds was first determined,and rape seeds with glucosinolate contents higher than 100 μmol/g were then selected for indoor fumigation assays to evaluate their inhibitory effects on the mycelial growth of 5 pathogenic fungi:Rhizoctonia solani,Fusarium solani,Phytophthora capsici,Verticillium dahliae Kleb,and Sclerotinia sclerotiorum(Lib)de Bary.Results showed that among the seeds of the 7 rape varieties or lines,Long12PZ16-65,16QP-65,Longyou 7,and R0162 had glucosinolate contents higher than 100 μmol/g,reaching 142.68,132.64,125.17,and 162.64 μmol/g,respectively,whereas Longy-ou 8,R0153,and R0157 had glucosinolate contents of 68.87,40.79,and 42.08 μmol/g,respectively.The indoor antifungal assay showed that R0162 exhibited high fungicidal activity against all 5 pathogens and had the strongest inhibitory effect,with a mycelial in-hibition rate of 100%.Long12PZ16-65,16QP-65,and Longyou 7 showed peak mycelial inhibition rates of 84.8%to 94.8%against R.solani,82.1%to 90.1%against S.sclerotiorum,and 68.7%to 77.3%against V.dahliae.Their inhibitory effects against F.solani varied considerably,with peak mycelial inhibition rates of 59.3%to 77.7%,while the highest mycelial inhibition rate against P.capsici was only approximately 50.0%.Therefore,rape seeds with different glucosinolate content showed different inhibitory activities against dif-ferent pathogens,while R0162 showed broad-spectrum inhibition fungal activity.R0162 could be used as a material with biological fu-migation and green manure in the prevention and control of vegetable soil-borne diseases.关键词
