菌核病对关中地区不同油菜品种产量及品质的影响
Effects of Sclerotinia sclerotiorum on the Yield and Quality of Different Rapeseed Varieties in Guanzhong Region
摘要
Abstract
In order to explore the resistance of different rapeseed varieties to Sclerotinia sclerotiorum and the impact of Sclerotinia sclerotiorum on the yield and quality of different rapeseed varieties in Guanzhong,Shaanxi Province,this experiment investigated the field incidence and disease index of Sclerotinia sclerotiorum during the maturity period of different rapeseed varieties in Guanzhong,Shaanxi Province,and measured indicators such as biomass,grain yield,oil content,glucosinolate content and erucic acid content.Results showed that when different rapeseed varieties were attacked by Sclerotia sclerotorum,there were significant differences in field disease incidence and disease index.Sclerotinia sclerotiorum reduced the biomass of rapeseed by 4.20%to 45.15%,the grain yield by 20.74%to 40.51%,and oil content by 0.32 to 3.78 percentage points,respectively,whereas the glucosinol content and erucic acid content were increased by by 2.83%to 40.64%and 11.02%to 87.85%,respectively,which seriously affected the yield and quality of rape.Among the 8 rapeseed varieties tested,2 varieties resistant to Sclerotinia sclerotiorum,namely Qinyou 797 and Heyou 919,were screened out.This can provide technical support for the screening,promotion,and application of rapeseed varieties resistant to Sclerotinia sclerotiorum in the Guanzhong region of Shaanxi Province.关键词
