摘　　要：试验以吉甜6号、粤甜3号为材料,进行了不同播期对超甜玉米生长发育的影响试验。结果表明:不同播期对超甜玉米的植株生长发育均有一定程度的影响,不同品种间性状变化规律差异不明显。变异系数分析表明,超甜玉米的株高和叶片数变化比较稳定;而穗位高变异程度最大,最易受环境影响;其次是生育期,变异系数较大,稳定性能较差。The effect of different sowing dates on the growth and development of super sweet corn were analyzed during the growth period of super sweet corn by using Jitian6 and Yuetian3 as material. The results indicated that there was a very significant difference in the characters of growth and development of super sweet corn under different sowing dates ,but the difference between varieties was not significant. The analysis of variation coefficient showed that the plant height and leaf number were comparatively stable while the variation coefficient of the growth period was relatively great or poorly stable, and the ear height was the most unstable.
