摘　　要：对13个辣椒品种进行低氮和高氮处理下的株高、叶绿素、生物学产量等农艺性状进行相关分析。研究发现,不同辣椒品种的植株高度和叶绿素含量存在明显差异,与氮素浓度无直接关系;不同辣椒品种的生物学产量存在较大差异,且受氮素浓度影响;兴蔬皱皮辣和兴蔬皱线1号的干质量显著大于其他品种。研究结果表明,植株鲜质量和干质量可以作为筛选氮高效辣椒品种的指标,故初步认为兴蔬皱皮辣和皱线1号是氮高效利用辣椒品种。The agronomic traits including plant height,chlorophyll content,and biological mass were analyzed in 13 pepper varieties grown under low nitrogen and high nitrogen conditions,respectively.The results showed that these varieties exhibited significant differences in plant heights and chlorophyll contents,but these differences had no direct relationships with the nitrogen treatments.Significant differences of biological mass were observed between different pepper varieties,which were also significantly affected by nitrogen concentrations.The dry weights of Xingshuzhoupila and Xingshuzhouxian No.1 were significantly higher than that of the other varieties under low nitrogen condition.These results demonstrated that fresh weight and dry weight of plants could be used as the indicators for screening nitrogen-efficient pepper varieties.According to these indicators,Xingshuzhoupila and Xingshuzhouxian No.1 were considered as the nitrogen-efficient pepper varieties.
