Adjusting Source–sink Ratio through Fruit Removal Affects Dry Matter Distribution and Fruit Set in Sweet Pepper
he fruit set ratio of sweet pepper (Capsicum annuum) can be represented as a regression curve using the source–sink ratio (SSR) for 1 to 7 days after anthesis (DAA) because both have positive correlation. We aimed to control the fruit set ratio by adjusting the SSR for 1 to 7 DAA. The sweet pepper…
