研究小麦幼穗分化是了解和掌握小麦生长发育规律的基础。小麦是“胎里富”的庄稼,群众早有“麦座四叶胎”的说法,那么小麦到底在什么时候开始座胎呢?这就需要了解小麦幼穗分化的时期和全过程。春小麦出苗后半月,只是生长叶片,当我们剥开叶片,(?)在分蘖节的顶端看到生长锥,这时茎节及叶的原始体已分化完毕。小麦一般在三叶展开时——分蘖开始的时候,生长锥开始伸长并转入幼穗分化,也就是座胎开始。出于小麦生长点被重叠的叶片、叶鞘所包被,不易直接观察,需用放大镜、显微镜
Studying the spikelet differentiation of wheat is the basis for understanding and mastering the law of growth and development of wheat. Wheat is “rich in the flesh” crops, the masses have long been “four-leaf barley wheat,” saying that when the wheat in the end when the beginning of the fetal it? This requires understanding of wheat spike period and the whole process. Spring wheat emerges half a month after emergence, but grows the leaves. When we peel the leaves (?), We see the growth cone at the top of the tillers, when the stems and leaf primordia have been differentiated. Wheat is generally developed at the time of the trefoil - at the beginning of the tiller, the growth cones begin to lengthen and begin to differentiate into young spikes, which is the beginning of the birth. Out of wheat growing point is overlapped leaves, sheath coated leaves, not directly observed, need to use a magnifying glass, microscope
