| 采用盆栽方法,研究了不同水分处理(田间最大持水量的40%、60%和80%)对不同专用型小麦籽粒灌浆特征和产量的影响。结果表明,在各处理下不同专用型小麦籽粒灌浆过程呈“S”型变化趋势,并用三次多项式对其进行模拟,其中,不同专用型小麦籽粒灌浆特征参数受水分处理影响不同。当水分处理为田间最大持水量的40%时,提高(早)了豫麦34籽粒各项灌浆参数,提高了豫麦49灌浆速率和粒重,提早了最大灌浆速率出现时间,提高了豫麦50灌浆持续期和粒重;60%处理下增加了豫麦49灌浆持续期,提早了豫麦50最大灌浆速率出现时间;80%时增加了豫麦49有效灌浆持续期,提高了豫麦50的灌浆速率。同时,豫麦34和豫麦50粒重与各灌浆参数均呈正相关,但差异均不显著;豫麦49粒重与灌浆持续期呈显著负相关,与平均灌浆速率呈显著正相关。豫麦34产量在60%处理下最高,且差异达显著水平;豫麦49和豫麦50产量在80%处理下最高,且差异分别达显著和极显著水平。 |

| In order to understand the effect of different water treatment on characteristics of wheat grain fill and Yield of wheat with specialized end-uses pot experiments were carried out at Henan Agricultural University Research Station during 2001～2003. The results are as follows: during the course of wheat grain fill, the process of the increase of grain's weight (that is, the process of grain fill) presents a shape of “S”, which is simulated by the Cubic Multinomial Equation, and the parameters in the above equations is different at different water treatments. At 40%, all the parameters were improved for Yumai 34, it increased (advanced) the rate of grain fill, grain weight and time of the maximum rate of grain fill for Yumai 49, and the period of grain fill and grain wheat weight were increased for Yumai 50; At 60% the period of grain fill was increased for Yumai 49, and the time of the maximum rate of grain fill was advanced; At 80% the effect period of grain fill was enhanced for Yumai 48, the rate of grain fill was add for Yumai 50. There is a positive correlation between the parameters and the grain wheat weight both for Yumai 34 and Yumai 50, but the correlationship weren't significant; there was a negative significance correlation between grain weight and period of grain fill, and a positive significance correlation between grain weight and rate of grain fill. As for Yumai 34, yield was increased significantly in 60%, For both Yumai 49 and Yumai 50, yield was highest in 80% and both of them were different significantly. |
