| 摘 要： | 以6个普通玉米品种为材料,在京郊大田条件下,采用裂区区组设计,分析干旱胁迫对不同基因型玉米产量及其构成因素的影响。结果表明,干旱胁迫显著影响了玉米产量(P0.01)、穗数(P0.05)、穗粒数(P0.05)和千粒重(P0.05),干旱胁迫对6个参试玉米品种产量影响存在显著差异(P0.05),其最终产量降低幅度为京农科728郑单958农华101MC703联创808登海618,其相应基因型穗数、穗粒数、千粒重等穗部性状与产量降低的趋势一致。

| Abstract: | The experiments were split randomized block designed, drought stress as the main block, genotypes as the sub-blocks, and sub-blocks were randomized within the main blocks. The results of this study showed that drought stresses significantly affected maize yield(P<0.01), ear density(P<0.05), kernel numbers per ear(P<0.05), and thousand kernel weight(P<0.05). Different genotypes cultivar significantly difference by drought stress(P<0.05), the yield decreased in JNK728 < ZD958 < NH101 < MC703 < LC808 < DH618, the corresponding genotypes of ear density, Kernel numbers per ear, and thousand kernel weight were the same trend as yield decreased. |
