个别的小麦品种特别是冬小麦,分蘖在获得高额产量上起着很重要的作用。春小麦品种留切先斯62第一个分蘖通常在主茎的第三或者至第四个真叶出现时形成。留切先斯62小麦的主茎生长圆锥突起的伸长在时间上与第三个真叶显现的时间相符合;同时也显露第一个分蘖。因此在此时期内明确主茎和分蘖的生长圆锥突起是怎样的和它在何时进行分化这是很重要的。我们在達里彦沃斯特农牧业科学研究所(位於哈巴罗夫斯克)研究了这个问题。供试品种为春小麦留切先斯62和其他几个品种。留切先斯62用马 Individual wheat varieties, especially winter wheat, play a very important role in obtaining high yields. Spring wheat cultivar Cheshire 62 The first tiller is usually formed when the third or fourth true leaves of the main stem emerge. The elongation of the conical protuberances of the main stems growing on the Cissus 62 coincided in time with the appearance of the third true leaf; the first tiller was also revealed. It is therefore important to know exactly what the growth cone of the main stem and tiller is and when it is differentiated during this period. We studied this issue at Darienstad Agricultural Science Institute (Khabarovsk). Test varieties for the spring wheat to keep cutting Xisi 62 and several other varieties.
