冷藏对郁金香鳞茎可溶性糖和蛋白质的影响

以郁金香鳞茎阿波罗、检阅、小黑人、普瑞斯玛、巴塞罗娜为试材,对不同冷藏处理时间的郁金香鳞茎不同部位的可溶性总糖、还原糖、蔗糖、可溶性蛋白质含量进行研究。结果表明:5个品种郁金香鳞茎在冷藏处理期间可溶性总糖、还原糖、蔗糖、可溶性蛋白质含量呈规律性变化。蔗糖是可溶性总糖的主要形式;初步认为解除休眠的过程是由外向内,通过鳞茎盘调节来实现的;5个品种郁金香鳞茎还原糖、蔗糖在第7周出现明显的波峰和拐点;检阅较其它4个品种表现出较高的可溶性糖含量和活性。

Effect of Cold Storage of Tulip Bulb on the Contents Total Soluble Sugar and Soluble Protein

Effects of cold storage of tulip bulbs of the cultivars of Apeldoorn,Parade,Nigrita,Purissima,Banja Luka Apollo during dormancy on the contents of nutrients contained in different parts of the bulbs were investigated,such as total soluble sugar,reducing sugar,sucrose,and soluble protein..Regular changes of the nutrients were observed in the bulbs of 5 cultivars.Sucrose was the main component of the soluble sugar.It was concluded preliminarily that the dormancy breaking occurred from outside to inside through the adjustment of the bulb.The contents of reductive sugar and sucrose reached their maximum values in the seventh week of the cold storage.Cultivar Parade exhibited higher contents of soluble sugar than other 4 cultivars.
