摘　　要：以桂椒12号五彩椒为试材,研究秋播和冬播的8个播期对五彩椒病毒病、果实性状和产量的影响,为桂南低海拔地区五彩椒高产栽培提供参考。结果表明,2次调查的秋播和冬播病毒病发病率和病情指数相似,第二次调查秋播五彩椒病毒病发病率均低于冬播,且秋播各播期病情指数变化幅度小。不同播期五彩椒商品果横径差异不显著,播期越晚果实纵径、纵横径比及单果质量越小。播期对五彩椒产量影响较大,产量随播期推迟呈下降趋势,其中秋播D1(7月24日)和D4(9月26日)播期小区产量分别为6.70 kg和6.40 kg,均极显著高于其他各播期。综上所述,五彩椒适宜在桂南低海拔地区秋播。The effects of 8 sowing dates in autumn and winter on the virus disease,fruit characters and yield of colorful pepper were studied by using Guijiao No.12 colorful pepper as material,which would provide a reference for high yield cultivation of colorful pepper in low altitude areas of South Guangxi.The results showed that the trend of viral diseases incidence rate and disease index were similar between in autumn and winter sowing.The incidence rate and disease index in autumn were significantly lower than those in winter,the change range of disease index in autumn sowing period was not obvious.There was no significant difference in the transverse diameter of commercial fruit at different sowing dates.With the delay of sowing dates,the longitudinal diameter of fruits became shorter,the fruit length and width ratio were decreased,and the single fruit weight became lighter.Meanwhile,the yield was decreased with the delay of sowing dates.At D1(24th Jul)and D4(26th Sept)autumn sowing dates,the plot yield were 6.70 kg and 6.40 kg respectively,which were significantly higher than those at other sowing dates.Therefore,the colorful pepper was suitable to sow in the southern Guangxi low altitude areas in autumn.
