摘要
长期以来,在小麦矮化育种工作中一直存在着一个较大难题,即在矮化品种选育上,不论矮秆亲本,还是分离出的矮秆材料,乃至培育成功的矮秆品种。
This paper shows the following results:1.The second heat source of wheat populations hasa significant effect on plant temperature distribution,2.The second heat source of dwarfwheat population has a higher temperature level and stronger emitting power than those of tailone,3.Under the influence of the second heat source,plant temperature is higher for dwarfwheat population,especially during milk stage,which easily accelerates wheat senescenceand even causes damages,4.By transforming the second heat source,the senescence processof dwarf wheat can be retarded and the early senescence can be prevented.
