| 摘 要： | 以15个CIMMYT选育的耐旱品系及其与津巴布韦耐旱玉米种质组配的不同世代的种质为材料,采用充足灌水与水分胁迫相对照的方法对玉米的雌雄穗开花间隔(ASI)与产量的关系进行了研究.结果表明在水分胁迫条件下ASI与产量呈显著的负相关.并对影响ASI的一些因素及其影响产量的潜在原因进行了探讨.

| Abstract: | Fifteen materials including CIMMYT bred drought tolerant germplasm and crosses of CIMMYT mate-rial and Zimbabwean drought tolerant germplasm were used.The relationship between anthesis -silking interval(ASI)and yield was studied by using well watered and water stressing methods.The results showed that:there is a significant negative correlation between ASI and yield.The underlying reasons of the effect of ASI on yield were also discussed in this paper. |
