| Abstract: |
| With Longmi10 as test cultivar, effect of irrigation treatment at different growing stages on main morphological characteristics and yield of broom-corn millet was studied at DunHuang city with an annual rainfall less than 40 mm. The results showed that both the broomcorn millet maturation
and the period from jointing stage to heading stage were prolonged under deficit irrigation. The plant height, 1000 grains weight, and grain yield were reduced, the main spike length was shortened, and main stem diameter was decreased. In addition, spike weight, grain weight, and spike number were materially affected by water deficit at heading and filling stages. There existed positive correlati
on between grain weight, panicle weight, plant height, main stem diameter, main panicle length, spike number, and grain yield under different soil water conditions. |
