Abstract

Abstract: In the study, we resarched the resistant capability of the grafted and self-rooted pepper to high temperature under greenhouse in summer conditions. The rootstock of the grafted pepper was wild pepper variety named Very Strong Bell, the scion and self-rooted pepper were both Kejiaoerhao. The results showed that the effect of high temperature on pepper leaves was more obvious than sub-high temperature. Both under high and sub-high temperature conditions, proline content and POD activity of the grafted pepper leaf were significantly higher than self-rooted, while the relative conductivity, MDA content and the production rate of Superoxide Anion of the grafted pepper were lower than self-rooted. These results highlight that grafting can significantly improve the heat resistance of pepper.

Key words: Pepper, Grafting, High temperature, Heat resistance
