Effect of Different Preservative Bags on Postharvest Storage Quality of Mini-Tuber Seed Potatoes from Aeroponic System
摘要
Abstract
In order to clarify the effect of different preservative bags on postharvest storage quality of mini-tuber seed potatoes from aeroponic system,'Atlantic'mini-tuber seed potatoes were used as materials,the storage and preservation effects of four types of preservation bags on the mini-tuber seed potatoes were investigated by measuring the weight loss rate,germination rate,decay rate,and related physiological indicators of the seed tubers during storage.The results showed that at(20±1)℃,compared with ordinary mesh bags(CK),four types of preservation bags,including ordinary A-film bags,nano preservation bags,walnut preservation bags,and garlic sprout preservation bags,could effectively improve the storage and preservation effect of mini-tuber seed potatoes.Among them,walnut preservation bags and nano preservation bags had the best storage and preservation effect on mini-tuber seed potatoes.Using these two types of preservation bags for package could significantly reduce the weight loss rate of mini-tuber seed potatoes,and mini-tuber seed potatoes packaged in nano preservation bags had the lowest decay rate,after 84 days of storage,the weight loss rates of mini-tuber seed potatoes packaged in walnut preservation bags and nano preservation bags were reduced by 73.20%and 63.62%compared with CK,respectively.The decay rate of mini-tuber seed potatoes packaged in walnut preservation bags increased by 21.43%compared with CK,while the decay rate of mini-tuber seed potatoes packaged in nano preservation bags decreased by 31.25%compared with CK.They could inhibit the rising speed of relative conductivity and malondialdehyde(MDA)content,and reduce the damage of cell membrane,after 70 days of storage,the MDA contents of mini-tuber seed potatoes packaged in walnut preservation bags and nano preservation bags were reduced by 23.26%and 13.95%compared with CK,respectively.At the same time,they could also promote the activities of peroxidase(POD),catalase(CAT)and superoxide dismutase(SOD),reduce the damage of oxygen free radicals,and make potatoes germinate normally,so they had a good storage and fresh-keeping effect on aeroponic cultured micro seed potatoes.By comprehensive consideration,it is recommended to use nano preservation bags for package during the storage of mini-tuber seed potatoes from aeroponic system.关键词
