摘要
对河南省主要玉米杂交种的形态特征及群体生理特性的研究结果表明,紧凑型玉米杂交种具有叶夹角小,叶向值大,叶长、叶宽、叶面积分布较合理,透光性能好,耐密性强,叶面积系数大且维持时间长等优点。且群体生长速率快,叶绿素含量高,光合作用强,光合势大,干物质积累强度高。
The study shows that the compact-type corn hybrids in Henan possess many advantages in comparison with the spread-type ones. Their good points are mainly as follows: smaller leaf angle; greater leaf orientation value, LAI, LAD and CGR; better spread of leaf length, leaf width, leaf area and population light penetration; higher suitability for intensive planting.
