Abstract
To evaluate characteristics of grain filling and yield in broomcorn millet resulting from effects of water stress at different developmental stages,Yumi 2 was employed as the experimental material for a pot trial. At the time of jointing,booting,and flowering and mature stages under water stress at two levels(moderate: 40% ~45% of field capacity,severe: 20% ~ 25% of field capacity),the grain filling processes of superior and inferior grains were studied using Richards equation. Also,the relationships between grain filling characteristics,and dry matter accumulation and translocation after heading,and yield,were analyzed. Compared with the control,severe water stress decreased initial grain-filling potential,delayed the time reaching the maximum grain-filling rate,shortened grain filling time,reduced grain filling contribution rate of middle and later stages,and decreased matter translocation percentage from stems and sheaths to spikes,influencing seed-setting rate and the yield. In addition,the kernels per spike and kernel weight per ear under severe water stress at booting stage were reduced by 44. 62%and 38. 19%,respectively,which represented the maximal decreased levels with the treatments. Moderate water stress promoted the grain filling process,improved the matter translocation percentage from stems and sheaths tospikes,increased seed-setting rate and grain plumpness,and enhanced the yield. The yield reached its highest level under moderate water stress at shooting stage,with increases of 24. 17%,17. 92%,7. 19% and 41. 14% in kernels per spike,seed-setting rate,1000 grain weight and kernel weight per ear,respectively. Therefore,proper water stress may improve the initial grain-filling potential,the grain filling rates at early and middle stages,and matter translocation percentage from the stems and sheaths to spikes,providing an plausible approach to the enhancement of the yield in broomcorn millet.
