摘　　要： 为了筛选出符合市销和出口要求的优质芥蓝品种,研究出芥蓝最适宜的低温贮藏保鲜方法,笔者对4个芥蓝品种进行了产量及品质测定,对不同温度、不同品种和不同保鲜剂处理在贮藏过程中的蛋白质、可溶性糖、维生素C、叶绿素等成分的变化及保鲜效果进行了研究.结果表明:1)“耐热中花”是目前生产上较优质、耐贮运的品种之一;2)芥蓝最适宜的低温贮藏温度为1 ℃,在此温度下贮藏30 d可保持叶片基本绿色;3)复合保鲜剂能有效地减缓芥蓝在贮运过程中营养物质的下降,延迟衰老. The experiment was carried out the variety screening and study on the freshness retention technology of Chinese-kale.Four Chinese-kale varieties:Shantou middle maturity Chinese-kale(SMK),GAAS middle-late Chinese-kale(MLK),SCAU heat-resistant middle maturity Chinese-kale(RMK) and Hongkong middle maturity Chinese-kale as the control(CK),were evaluated in yield and quality components;the contents change of protein,soluble-sugar,V-C,and chlorophyll in different temperature(1,3,5,7 ℃),different varieties(SMK,MLK,RMK,CK) and different reagents of freshness retention(Tecator and The Compound Reagent of GAAS) were analysed.The results show:1)RMK is one of the high quality and long-store variety at present; 2)the suitable temperature of Chinese-kale freshness retention is 1 ℃,and at this temperature the vegetable leaves are still green in 30 days;3)the Compound Reagent of GAAS can effectively lessen the nutrition declining and delay caducity.
