Effect of Harvest Time on Physiological Property and Storage Quality of Agaricus bisporus
摘要
Abstract
The characteristics of physiological and biochemical changes of Agaricus bisporus strain W-192 harvested at three different times (according to the fungus lid and growth period, fungus lid 2 - 3 ,3 -4 ,4 - 5 cm were marked as harvest times I , II and IH respectively) in low temperature storage (4 ± 1 ) ℃ were studied systematically , these indexes included water content, percentage cap opening, browning degree , the respiration rate, total poly-phenol, polyphenol oxidase ( PPO) activity and malondialdehyde. Compared with harvest time Ⅰ and Ⅲ , the appearance of respiration peak of harvest time II was later about 3 days, the content of malondialdehyde was always at a low level and it also had higher water content in early storage, white degree maintained good in late storage, while percentage cap opening was lower than the other two groups, harvest time Ⅱ had a better storage quality. From the analysis of fresh-keeping performance, Agaricus bisporus strain W-192 should be harvested at harvest times II , while from biological yield the harvest times Ⅲ is appropriate for upcoming Agaricus bisporus.关键词
