对10个不同青花菜品种（系）的生育期、植株形态及叶、花球、茎三种主要器官中的主要营养成分进行比较分析。结果表明：34＃的株型适于密植，主球单重较大，可作为早熟高产青花菜品种进行推广种植。可溶性蛋白含量为叶﹥花球﹥茎，5＃、16＃、34＃及35＃各器官中可溶性蛋白含量较高，30＃各器官含量均最低；大多数品种（系）叶和花球的维生素 C 含量较高，茎中含量较低，15＃、20＃中维生素 C 含量较高；花球中的纤维素含量普遍低于叶和茎，5＃、16＃及20＃中纤维素含量较高；干物质含量为叶﹥花球﹥茎，20＃、30＃及35＃中干物质含量较高；可溶性糖含量为茎﹥花球﹥叶，5＃和29＃中可溶性糖含量较高。总体来看，20＃及35＃各器官中营养成分明显高于其它品种（系），综合营养品质较突出；青花菜的茎和叶中营养成分较高，可加以开发以提高其综合利用价值。%The growth period,plant morphology and the main nutritional ingredients of leaf,head and stem of 10 broccoli varieties (lines)were analyzed.The results showed that the plant type of 34#was suitable for high density cultivation.The weight of single main head of 34#was the highest and could be used as a pre-cocious high -yielding broccoli variety to promote the cultivation.The soluble protein content in leaf,head and stem was in order and that in each organ of 5 #,16 #,34#and 35 #was higher,while that in 30#was the lowest.The Vitamin C content in leaf and head was higher than that in stem and that of 15 #and 20#was high-er.The cellulose content in ball -flower was lower than that in leaf and stem,and that of 5 #,16 #and 20#was higher.The dry matter content in leaf,ball -flower,stem was from high to low and that of 20#,30#and 35 #was higher.The soluble sugar content in stem,ball -flower and leaf was in order and that of 5 #and 29 #was higher.Overall,the nutrients in 3 organs of 20#and 35 #were significantly higher than those of the other varie-ties with outstanding comprehensive nutritional qualities.The nutritions of broccoli stem and leaf were higher, which could be developed to improve the comprehensive utilization value.
