摘要
花椰菜（Ｂｒａｓｓｉｃａｏｌｅｒａｃｅａｖａｒ．ｂｏｔｒｇｌｉｓ）各器官间密切相关，其中花球重与叶重、茎直径关系最为密切，相关系数分别为ｒ＝０．７７０３和ｒ＝０．８０２３。肥水条件与植株总重和各器官重呈正相关关系。去叶和断根的结果表明，在试验范围内，去叶越多，去叶越晚对植株总重和花球重影响就越大。同样断根越多，断根越晚，对花球重的影响就越大。
The correlation between curd weight and other organs of cauliflower C.V.Holland Snowball was studied by the way of removing leaves,cutting root and connolling conditions of different fertility and water.The results show that there is a couse correlation between curd weight and weight of other organs the closest positive correlation between curd weight and leaf weight and diameter of stem.The correlative coefficient is r=0.7703 or=0.8023,respectively.There is positive correlation between condition of fertility and total weight of curd weight.The result of removing leaves and cutting root showed that effect on total weight of plant and curd weight had greater more and later removings leaves and cut root.
