| Abstract: | Five plant densities were tested to study the photosynthetic characteristics and yield components of DU01,a new pepper variety suitable for one-time harvest.The results showed that after full fruit stage,the leaf area,Gs,Ci and Tr of DU01 decreased with the increase of density,and Chla,Chlb,Car and Chlt increased with the increase of density.Fruit weight decreased with the increase of density.The yield and economic return increased with the increase of density,and the highest density produced highest yield.High plant population was sufficient to make up for the disadvantage of small fruit weight.Yield and economic profit were the highest with plant density of 5.13 million plants·hm-2.Plants of DU01 at population of 5.13 million plants·hm-2,the functional leaves stayed green longer for photosynthesis,and produced high yield. |
