水稻植株各部分在形态上的很大变异与生产潛力有密切的关系。这些变异包括:茎稈的粗细、高度、数目和坚韧性方面具有明显的差异;叶片的色泽、厚度、角度、长度和宽度的变异;以及稻穗的大小和着粒密度的差异。最理想的株型综合在一个品种里,特
There is a close relationship between the morphological variations of rice plants and their potential productivity. These variations include: significant differences in stem thickness, height, number, and tenacity; variability in leaf color, thickness, angle, length, and width; and differences in panicle size and grain density. The best plant type integrated in a variety, special
