Research progresses on the effects of preharvest treatments on posthar-vest preservation of tomatoes
Tomato(Solanum lycopersicum L.)has a unique flavor and rich nutrition,which is highly favored by consum-ers.However,mature tomatoes have a lower shelf life due to their soft flesh and thin peel.Preharvest infectious diseases are difficult to prevent and control after harvest.The vast majority of postharvest pathogens have already infected tomato fruits as early as the production stage and remained quiescent.When mechanical damage occurs in the fruits during har-vesting,storage,transportation,and sales,these pathogens begin to infect fruits,causing pathological decay and complete loss of commercial value.Therefore,preharvest prevention and control are crucial.In addition,preharvest treatments widely affect postharvest physiology,which in turn affect the shelf life of fruits.At present,relying solely on postharvest technology is not enough to fulfill the development needs of the current tomato industry,therefore,preharvest treatments are gradually receiving attention.This article reviews the research on improving the postharvest quality and shelf life of to-matoes through preharvest chemical control,biological control,and physical measures both domestically and internation-ally in recent years.Based on the current research status,prospects are proposed to provide reference for the future re-search,application,and development of tomato preharvest preservation treatment technology.
