Abstract:: Taking ‘Huang Guiren’ color pepper as test materials，the effect of ‘Pulyutong’ plant immune protein on growth，yield，fruit quality and resistance of color pepper in organic production systems were studied adopting two factor randomized block design.The results showed that all the treatments improved the plant growth，disease resistance，yield and quality of color pepper.The plant yield，plot yield and yield per acre of treatment T2(applying at seedling stage+foliage spray after planting+root-irragation) and T02(no applying at seedling stage+foliage spray after planting+root-irragation) were significantly（P<0.05） higher than other treatments increased by 64.38% and 50.20%，respectively.Vitamin C content of T2 and T02，increased by 10.75 mg/100g and 9.12 mg/100g respectively，which were also significantly（P<0.05） higher than other treatments.Meanwhile，the soluble solids content of T2 and T02 increased by 3.04% and 2.26%，respectively.What’s more，the effect of prevention for thrips of T2 and T02 were up to 96.9% and 90.30%，respectively，after 7 days later significantly（P<0.05）higher than other treatments，too.The results showed that ‘Pulyutong’ plant immune protein had important influence on the growth，yield，fruit quality and resistance of color pepper in organic production systems.T2 and T02 method were recommended in the production of organic color pepper cultivation.
