试验结果表明:抗旱品种具有较大的LAI,达峰值后稳定的时间久且下降也较缓慢;LAD高;干物质积累快,最终值亦大;穗粒数多、花粉败育率低、抗旱系数高。
The results showed that drought-tolerant cultivars had larger LAI, which reached a stable peak after a long time and declined more slowly; LAD was high; dry matter accumulation was rapid and the final value was also large; High coefficient.
