在大白菜(或其它作物)花粉单倍体育种过程中,不管是从愈伤组织还是从胚状体分化出绿苗,并长成幼小完整植株时,在我国的多数地区都正处于高温炎夏季节,花培室在没有空气调节设备的情况下,温度常常高达30℃左右。造成花培幼苗生长缓慢、黄弱,甚至大量死亡。而电冰箱容量有限,大量冷藏又有困难。另外,幼苗在电冰箱中不能进行正常的光合作用,不但生长处于停滞状态,而且常使壮苗变弱,死苗率也很高。因此,夏季高温严重障碍着这一工作的顺利
In Chinese cabbage (or other crop) pollen haploid breeding process, either from callus or from embryoid body differentiation of green seedlings and grow into young complete plants, in most parts of our country are in high temperature summer Season, flower cultivation room in the absence of air conditioning equipment, the temperature is often up to about 30 ℃. Resulting in flower growth slow, yellow weak, or even a large number of deaths. The refrigerator capacity is limited, a large number of cold storage difficulties. In addition, seedlings in the refrigerator can not be normal photosynthesis, not only the growth in stagnation, and often weak seedlings, dead shoot rate is also high. As a result, the heat of summer has severely hampered the success of this work
