The Photosynthetic Characteristics of Different Purple Peppers

Abstract

The yield of pepper with purple leaves (PF) is low, while the pepper with green leaves (GM) is not resistant to strong light and high temperature. In this study, we analyzed the photosynthesis characteristics and genetic stability of their hybrid progenies using PF(CS3) and GM(SJ11-3) as controls. Based on the decreased purple color and increased green color, the hybrid pepper was divided into five groups: Z1, Z2, Z3, Z4 and Z5. Results showed that as the purple color increased, the anthocyanin content in leaves increased. Simultaneously, we found that PF exhibited higher resistance to strong light and high temperature. Thus, the purple hybrid progenies with higher photosynthetic rate were recommended, as they showed higher yield and better resistance to strong light and high temperature.
