小麦花粉植株的越夏与“低温蹲苗”在冬小麦种植地区,进行小麦单倍体育种时,花药的接种工作多在4—5月间进行,花粉幼苗则在5—6月陆续诱导分化出来,由于花粉植株是在培养基上(试管或三角瓶内),在温度和湿度相对稳定的条件下培养生长的,幼苗比较细弱,移出后对外界条件的适应性较差,再加上不久就进入炎热的夏季,这时的气候条件很不适应幼苗的生长发育,死亡率高。因此,研究解决单倍体小麦的越夏 Summer wheat pollen plants and “low temperature squatting seedlings” in winter wheat growing areas, wheat haploid breeding, anther inoculation work mostly in the April-May period, pollen seedlings gradually induced from May to June differentiation, As the pollen plants are cultured on the medium (test tube or flask), under the conditions of relatively stable temperature and humidity, the seedling is relatively weak, and the adaptability to the external conditions after removal is poor. In addition, it soon enters Hot summer, when the climatic conditions are not adapted to the growth of seedlings, high mortality. Therefore, the study to solve the haploid wheat summer
