研究小麦的生长发育过程和苗、株、穗、粒动态结构,是深入揭示小麦生物学特性,掌握其生育规律,为选用和选育良种,不断改进栽培技术提供依据的一项重要工作。今年,我们在以前分项研究的基础上,对区内两个小麦主体品种河套三号(白欧柔)、卡捷姆及耐高温抗早衰的红芒等三个代表性品种,进行了比较系统的叶(出生与定长及消亡过程)、蘖(分蘖动态及规律)、茎(各茎节长度及开始伸长与停止期)、穗(幼穗
Studying the growth and development of wheat and the dynamic structure of seedlings, plants, spikes and grains is an important work in revealing the biological characteristics of wheat in depth and grasping the rules of its growth, providing the basis for selection and breeding of improved varieties and continuous improvement of cultivation techniques. This year, on the basis of the previous sub-studies, we compared three representative varieties of two major wheat cultivars, Hetai No.3 (Baiou Rou), Kadam and Hongmang, which are resistant to high temperature and premature aging. The length of leaf (growth and decay of birth and death), tillering (tillering dynamics and regularity), stems (length of each stem and the beginning of elongation and stopping), panicles
