在干旱地区,缺水会抑制小麦植株的生长和代谢,因此选择适合的品种是一项重要的任务。最近,已经育出携带不同半矮秆基因数目的不同株高的小麦类群,并通过诱发突变得到从很矮到很高的小麦类群。现在,育种工作者面临的问题是:选择最好的株高类群以适应特殊的农业气候条件。本研究的目的是在缺水条件下,根据经济产量,生物学产量、收获指数以及其它产量组成成分,评价不同株高的春小麦的生产效率。
In arid regions, water scarcity will inhibit the growth and metabolism of wheat plants, so choosing the right species is an important task. Recently, wheat lines of different plant height carrying different numbers of dwarfing genes have been bred and from low to very high wheat populations have been obtained by induced mutations. The problem facing breeders now is to choose the best plant height class to suit their particular agro-climatic conditions. The objective of this study was to evaluate the productivity of spring wheat at different plant heights under water deficit conditions based on economic yield, biological yield, harvest index and other yield components.
