Abstract:

In order to study the effect of intercropping on selenium rich cultivation of cherry tomato, pot experiment was used, and the effects of different intercropping modes (red, yellow, purple monoculture, red and yellow intercropping, red and purple intercropping, yellow and purple intercropping, red, yellow and purple intercropping) on fruit quality and selenium content were studied. The results showed that different intercropping patterns decreased the single fruit weight and fruit shape index of red and yellow cherry tomato, increased the single fruit weight and fruit shape index of purple cherry tomato, and increased the selenium content in root, stem, leaf and fruit of three cherry tomato varieties. The contents of lycopene, carotenoid and anthocyanin in purple cherry tomato were increased by yellow and purple intercropping. The contents of vitamin C and carotenoid in red cherry tomato were increased by intercropping three genotypes. Intercropping improved the fruit qualities of red and purple cherry tomatoes, and increased the selenium content in each part of three genotypes of cherry tomato. Therefore, intercropping was conducive to the selenium rich cultivation of cherry tomato.

Key words: intercropping, cherry tomato, fruit quality, selenium
