三种基因型樱桃番茄混种对果实品质和硒含量的影响

Effects of intercropping with different genotypes of cherry tomato on fruit quality and selenium content

为研究混种对樱桃番茄富硒栽培的影响,采用盆栽试验,以红(Y20-1)、黄(小番茄-4-1)、紫(咖番-13-1)樱桃番茄为材料,研究了不同混种模式(红色、黄色、紫色单种,红黄、红紫、黄紫两两混种,红黄紫混种)对果实品质和硒含量的影响。结果表明,不同混种模式降低了红色和黄色樱桃番茄的单果质量和果形指数,提高了紫色樱桃番茄的单果质量和果形指数,提高了3种樱桃番茄根、茎、叶与果实中的硒含量。黄色和紫色混种提高了紫色樱桃番茄的番茄红素、类胡萝卜素和花青素含量。3种基因型混种提高了红色樱桃番茄维生素C和类胡萝卜素含量。相互混种提高了红色和紫色樱桃番茄的果实品质,并且提高了3种樱桃番茄各部位的硒含量,所以混种有利于樱桃番茄的富硒栽培。

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.
