摘要
研究6个超甜玉米品种在春季和秋季种植的产量和主要农艺性状的表现。结果表明:不同种植季节对产量、生育期及株高、穗位、单穗重、行粒数、穗粗、籽粒可溶性固形物含量等性状产生显著影响。其中,秋季种植的产量、单穗重、穗粗、籽粒可溶性固形物含量显著或极显著高于春季种植的,而生育期、株高、穗位则显著低于春季种植的;穗位比例、穗长、秃顶等性状则较少受到种植季节因素的影响,能够稳定显示出品种的特征;多数超甜玉米品种秋季种植产量高且品质优良。
Six varieties of sweet corn were planted in spring and autumn to observe their yield and several agronomic traits. The results showed that planting season had significant effects on agronomic traits such as yield, growth stage, plant height, ear height, weight per ear, grain number per row, ear diameter, grain soluble solid content, etc. The yield, ear weight, ear diameter, grain soluble solid content of the sweet corn planted in autumn were significantly or highly significantly higher than those in spring,...
