| 摘 要： | 选用先玉335（XY335）、郑单958（ZD958）和登海661（DH661）为试验材料，研究不同品种间玉米子粒乳线比例与子粒含水量、粒重及营养物质积累的关系。结果表明，XY335的乳线下移要快于ZD958和DH661，且其千粒重最大、含水量最低；品种之间可溶性糖和蔗糖含量差异不明显，DH661的淀粉含量显著低于XY335和ZD958；乳线比例与淀粉含量及千粒重呈极显著正相关，与子粒含水量、可溶性糖、蔗糖及蛋白质之间呈显著负相关。

| Abstract: | Three cultivars XY335, ZD958 and DH661 were used to analyze the relationship among kernel milk line formation, water content, grain weight and nutrients accumulation of summer maize. The results showed that XY335 kernel milk line formed faster than ZD958 and DH661, and whose 1 000-kernel weight was the maximum and water content was the minimum, soluble sugar and sucrose content was not significantly different in cultivars. The starch content DH661 was significantly lower than XY335 and ZD958. Correlation analysis showed that kernel milk line formation had a positive correlation with kernel starch content and kernel weight, while milk line formation was negatively correlated with kernel water content, soluble sugar, sucrose and protein content significantly. |
