摘要
对六种十字花科蔬菜作物叶片网状脉进行了定量研究。结果表明,叶脉级数与叶脉分叉角度之间存在着正相关关系,即叶脉级数越高,分叉角度越大;一、二级叶脉之间的分叉角度可能成为十字花科蔬菜作物不同物种的一个特征,并对各级叶脉长、前四级叶脉和脉岛的数量性状及各级叶脉和脉岛的发育机理进行研究。
Based on the six kinds of cruciferae vegetable leaves reticuleate vein quantitative study which showed that： there was positive correlation between the series and the bifurcate angle of nervation, the higher the series of nervation, the bigger the bifurcate angle. And the bifurcate angle of nervation between the first and second degree was likely to be a feature among different varieties in cruciferae vegetable. The paper studied the quantitative characters of each levels vein length, the former four levels vein and areole, and preliminary investingated the development mechanism of all levels vein and areole.
