为揭示沿淮稻茬麦区不同小麦品种籽粒灌浆特性与粒重的关系，以23份小麦品种为材料，利用Richards方程对籽粒灌浆过程进行模拟，分析粒重与籽粒灌浆特性和籽粒表型间的关系。结果表明，不同小麦品种粒重和灌浆特征参数主要受基因型控制；Richards模型拟合的理论千粒重趋势与实测值高度一致。不同粒重类型品种（高、中、低）间单粒最大灌浆速率和单粒平均灌浆速率存在显著差异，而灌浆期持续时间、活跃灌浆期天数、最大灌浆速率出现时间无显著差异。高粒重、中等粒重和低粒重类型品种的籽粒灌浆速率差异主要集中在快增期，其中高粒重和中等粒重类型品种的平均灌浆速率在快增期比低粒重类型品种分别高16.94%和10.34%，单粒平均灌浆速率分别高16.01%和10.46%。不同粒重类型品种的籽粒长、宽、周长和表面积均存在显著差异，均表现为高粒重>中等粒重>低粒重，籽粒长宽比差异不显著。相关性分析显示，千粒重与籽粒长、宽、周长、表面积及其灌浆速率呈显著正相关（P<0.05），相关系数为0.88~0.99。综上所述，籽粒库容量（粒长、粒宽等）与快增期灌浆速率的差异是不同粒重类型小麦品种粒重分化的主要原因。

Abstract

收起

To investigate the relationship between grain-filling characteristics and grain weight of different wheat varieties in rice-wheat cropping area along the Huaihe River, 23 cultivars were used in this study. The grain-filling process was simulated using the Richards model, to analyze the relationships between grain weight, grain-filling characteristics, and grain phenotype. Results indicated that grain weight and grain-filling parameters were predominantly governed by genotype. The theoretical thousand-kernel weight (TKW) predicted by the Richards model closely aligns with the field-measured values. Significant differences were observed among cultivars of differing grain-weight classes in terms of maximum single-grain filling rate and average single-grain filling rate. Whereas, no significant differences were detected in filling duration, number of active filling days, or the timing of peak filling rate. Differences in grain-filling rates among the three grain-weight classes high-, medium-, and low-grain-weight were primarily confined to the rapid grain-filling phase. The average grain-filling rate of high-grain-weight and medium-grain-weight cultivars increased by 16.94% and 10.34%, respectively, compared with the low-grain-weight cultivars. The average grain-filling rate per single grain of the high-grain-weight and medium-grain-weight types increased by 16.01% and 10.46%, respectively. Grain morphological traits including grain length, grain width, perimeter, and surface area also significantly differed among grain-weight classes, consistently following the order: high-grain-weight>medium-grain-weight>low-grain-weight, whereas there was no significant difference for the grain length-to-width ratio among the cultivar groups. Correlation analysis revealed that TKW was significantly and positively correlated (P<0.05) with grain length, grain width, perimeter, surface area, and grain-filling rate, with correlation coefficients ranging from 0.88 to 0.99. In summary, this study indicates that the synergistic differences in grain size (e.g., grain length and width) and the rapid grain filling rate during the rapid growth period are the main reasons for the grain weight differentiation among different grain weight types of wheat varieties.
