Abstract

Abstract:

This article explores the effects of different contents of biuret on the growth of watermelons, peppers, and radishes. The activities of catalase (CAT) and peroxidase (POD), as well as the content of malondialdehyde (MDA), were measured in watermelons, peppers, and radishes with different contents of biuret, providing a theoretical basis for guiding the safe production of horticultural crops such as watermelons, peppers, and radishes. The results showed that biuret treatment could affect the growth of horticultural crops, especially the leaves of horticultural crops appeared yellowing and curling under high biuret content. With the increase of biuret content, CAT activities in watermelons and peppers showed a trend of first increasing and then decreasing, and POD activities in watermelons, peppers, and radishes also showed a trend of first increasing and then decreasing. In addition, MDA content of peppers and radishes showed a trend of increasing with the increase of biuret content.

Key words: biuret, horticultural crops, growth and development, physiological index
