Abstract

A pot experiment was conducted to study the effects of intercropping with Solanum photeinocarpum and Solanum nigrum from two climate-ecology regions (Ya'an campus and Chengdu campus) on photosynthetic characteristics of eggplant under cadmium (Cd) stress. Five treatments were used in the experiment: 4 eggplant seedlings were monocultured in one pot (CK), 3 eggplant seedlings intercropping with 1 S. nigrum seedling from Chengdu(henceforth LC), 3 eggplant seedlings intercropping with 1 S. nigrum seedling from Ya'an (henceforth LY), 3 eggplant seedlings intercropping with 1 S. photeinocarpum seedling from Chengdu(henceforth SC), 3 eggplant seedlings intercropping with 1 S. photeinocarpum seedling from Ya'an (henceforth SY). The results showed that intercropping enhanced net photosynthetic rate (Pn), transpiration rate (Tr) and stomatal conductance (Gs) of eggplant significantly. Intercropping with S. photeinocarpum was better than with S. nigrum. As to the same plant, the Pn, Tr and Gs of eggplant intercropping with the one from Ya'an campus (the Mountain-Central Subtropical-Cold Zone of the Western Sichuan Basin) was higher than with the one from Chengdu campus (the Central Subtropical-Long-Spring and Summer-Drought Zone). There was little difference from the result of Ci, compared with CK, after intercropping with S. photeinocarpum and S. nigrum, Ci of eggplant also increased, however, treatments of different climate-ecology regions were not significant. Therefore, intercropping with S. photeinocarpum and S. nigrum could use to enhance the photosynthetic ability of eggplant, which would help to improve the adaptability of eggplant.
