摘要: 对辣椒品种湘研16号进行了不同采后处理,研究了该品种辣椒在采后用不同浓度拮抗木霉菌(稀释600、800、1000倍)处理、不同厚度薄膜包装(0.02、0.03mmPE膜)处理后在室温条件下其腐烂率、VC、叶绿素变化的情况,以期找到适宜的辣椒采后处理方法以延长其在常温下的货架期。结果表明:经稀释600、800倍的木霉菌处理后的辣椒无论何种包装,贮藏4d,其腐烂率极显著低于其他处理,且腐烂率低于10%。0.02mmPE膜包装,稀释600倍的木霉菌处理腐烂指数上升最慢,且各个时期腐烂指数极显著低于其他处理。0.03mmPE膜包装时,稀释600、800倍的腐烂指数发展均较慢。用600倍木霉菌稀释液处理的辣椒,用0.03mmPE薄膜效果要显著优于0.02mmPE膜;用800、1000倍木霉菌稀释液、5×10-66-BA处理的辣椒及CK,0.02mmPE膜包装的辣椒腐烂指数总体低于0.03mm包装的辣椒。在保持VC方面,稀释1000倍处理的优于800倍的,800倍的又优于600倍的。510×10-66-BA处理的则略逊于不同稀释浓度的木霉菌处理的辣椒。而CK对VC的保存率则更差一些。不用任何保鲜剂处理,0.03mm厚的PE膜在VC的保存率上极显著优于0.02mm厚的PE膜。0.03mmPE膜包装对于抑制叶绿素分解和比0.02mmPE膜包装效果好。另外,发现拮抗木霉菌处理的辣椒保绿效果比果蔬采后处理中常用于保绿的6-BA的效果要好。

Abstract: The peppers,the cultivar of Xiangyan No.16, were treated with different concentrations of antagonistic Trichoderma spp. (diluted 600, 800 and 1000 ploidy), then packed into different PE bags (0.02, 0.03mm PE film in thickness) to study the effects of Trichoderma spp. and the thickness of PE bags on Cayenne peppers’s rotten rate, rot index, vitamin C and chlorophyll content during shelf life,and to find the favorite methods to prolong the shelf life at room temperature. For the Cayenne pepper treated with antagonistic Trichoderma spp. diluted 600, 800 ploidy,the rotten rate is significant lower than the else’s and CK’s after 4 days,and their rot rates are all below 10%. The pepper rot index packed into 0.02 mm PE bags and treated with 600 ploidy Trichoderma spp. rose very slowly, and it’s rot index values at each period are significant lower than the others’s. While the rot index of the pepper packed into 0.03 mm PE bags and treated with diluted 600 or 800 ploidy are all lower than the others’s. When the pepper treated with diluted 600 ploidy, packed in 0.03 mm PE bags is prior to the treatments packed into 0.02mm PE bags on rot index significantly, while when the pepper treated with diluted 800, 1000 ploidy, 5 ×10-6 6-BAand CK, packed into 0.02 mm PE bags is prior to the ones packed into 0.03 mm PE bags. On retaining VC, the treatment treated with antagonistic Trichoderma spp. diluted higher ploidy is prior to the lower one, at the same time, the effect of all of the treatments of antagonistic Trichoderma spp. on remaining VC is higher than the ones treated with 5×10-6 6-BA and CK. Without any preservations, using 0.03mm PE package is better than 0.02 mm’s. On the decreasing the decompose of chlorophyll, 0.03 mm PE bags is better the other. In addition, the effect of antagonistic Trichoderma spp. on remaining pepper’s green is better than 6-BA’s, used for remaining green of postharvest fruits and vegetables, popularly.
