冷藏大蒜在超市货架条件下发芽叶生长特点观察

对6批次不同时间入库冷藏的宋城大蒜,分4批次不同时间出库,出库后置于(16±1)℃,空气相对湿度75%的与超市货架条件相似的人工气候箱内存放,每隔3~6 d取样测量发芽叶和蒜瓣长度,计算芽/瓣比。结果表明:冷藏大蒜出库后芽/瓣比与入库时间和出库后存放时间有关,入库越晚,出库时芽/瓣比越大,出库后存放时间越长,芽/瓣比越大;芽/瓣比增加的速度与入库时间和出库后存放时间有关,入库越晚,出库后芽/瓣比增加越快,出库后存放时间越长,芽/瓣比增加越快。冷藏大蒜出库后芽/瓣比大于1.000的时间因入库时间和出库时间而不同。

Observaion on Garlic Shoot Bud Growth in Supermarket Shelf after Cold Storage

The garlics were regularly put into cold storage in 6 different times,and the samples were taken from cold storage and put into artificial climate chamber with the condition of(16±1)℃,75%RH in 4 different times.The length of shoot bud and clove was measured regularly and the ratio of the shoot bud length/clove length were calculated.The results showed that the shoot bud length and the shoot bud growth rate were all associated with the date of putting into cold storage and the time of deposition after stopping cold storage.The later the date of putting into cold storage,the bigger the shoot bud length and the faster the shoot bud growth rate was.The longer the deposition time after stopping cold storage,the bigger the shoot bud length and the faster the shoot bud growth rate was.The average time for the shoot bud length/clove length closing to 1.000 were different as the date of putting into cold storage and the time of stopping storage,respectively.
