摘要: 为明确群体水平上化杀型杂种小麦的光合优势表现特征及其生理机制,以2个化杀型小麦杂种F1及其亲本为材料,推广品种冀麦38号为对照进行了研究.结果表明:供试杂种小麦1F1和2F1的群体干物质生产能力都表现平均优势和超标优势.1F1起因于其LAI和光合势优势较大,2F1则是由于净同化率优势较大.1F1和2F1的子粒产量都高于亲本和对照,与亲本相比,1F1和2F1的产量优势是由产量构成三因素综合提高所致,与ck相比,1F1和2F1的产量优势则主要来自千粒重的提高.

关键词: 杂种小麦, 群体, 产量, 光合优势

Abstract: To clarify the characteristics of population photosynthesis of CHA wheat hybrids and their physio-logicaLbasis, a study was conducted with two CHA wheat hybrid F1 as tested materials and Jimai 38 as control.T he main results showed that, there were obvious average heterosis ( AH) and super-controLheterosis ( SH) on the population dry weight in two CHA wheat hybrids 1F1and 2F1, but the heterosis of 1F1 mainly came from the heterosis of LAI and photosynthetic potential, while the heterosis of 2F1came from that of net assimilation rate.T he grain yields of 1F1and 2F1 obviously surpassed their parents and ck.Compared to their own parents, the heterosis of 1F1and 2F1were caused by the increase of alLthe three yield components, but their SH of yield main-ly came from the increase of kerneLweight.
