| 摘 要： | 本试验以9个栽培红花品种为材料,进行了红花籽实含油率相关性状的通径分析。结果表明,种壳率是影响籽实含油率的首要因素,分枝高和株高次之。这3个性状两两间的互作效应大于单一性状对含油率的影响。对含油率的决定程度,以分校高与种壳率的互作效应居于首位。百粒体积和每果粒数保持相对稳定,降低种壳率或分枝高度,可有效提高含油率。其它性状不变,选择植株较高者,是提高含油率的有效途径。

| Abstract: | The experrnent of path analysis of characters relating to oil content of seed in safflower was conducted.The main results were as follows: The hull ratio was the main factor which influenced the oil content,the other factors were the height of the plant and its branches.The interactions between these three characters were bigger than the single character in influencing the oil content.The interaction between the branch height and the hull ratio of safflower was first important effect deciding oil content.If the volume of a hundred seeds and the number of seeds per achene were maintained in a relatively stable condition,reduction of either the hull ratio or the height of branches could improve effectively the oil content of the safflower.If the other characters are unchanged,selecting high plant is an effective way to raise the oil-bearing ratio of the safflower. |
