摘要

摘要在尼日利亚北部几内亚萨玛鲁地区，研究了播期(6月30日、7月15日和7月30日)对秋葵花叶Tymovirus (OMV)发病的影响。随着播期的推迟，每块地平均捕获带病毒甲虫的数量减少，而感染omv的植株百分比随着播期的推迟而增加。随着播种的延迟，疾病的严重程度也会增加，而果实产量则会下降。

Effect of Sowing Date on the Incidence and Severity of Okra Mosaic Tymovirus

ABSTRACT The effect of sowing date (June 30th, July 15th and July 30th) on the incidence of okra mosaic Tymovirus (OMV) was investigated at Samaru, Northern Guinea Savanna Zone of Nigeria. The average number of virus-vectoring beetles caught per plot decreased with delay in sowing, while percentage of OMV-infected plants increased with delay in sowing. Disease severity also increased with delay in sowing while fruit yield decreased.
