Thus, attempts are being made to decrease postharvest losses and extend storage life by harvesting at physiological maturity and pre cooling. The physiological maturity stages in the tomato fruit are described as mature green, breaker, yellow, pink, and red. Mature green tomato has a yellowish 'star' on the blossom end, but the only definitive test of maturity is to cut the tomato in half and observing the seeds. The cut seed is a sign immature fruit . The breaker stage occurs after the mature green stage and is distinguished by the development of pale yellow coloration on the blossom end.
