摘要: Two melon cultivars ('Tam Dew' and 'Kalakesai') were used to study the effects of benzothiadiazole (BTH) and salicylic acid (SA) treatment at florescence stage on assimilate allocation, fruit yield and quality of melon. The results showed that fruit weight and yield of melon were increased significantly after 0.25 mmol.L-1 BTH and 1 mmol.L-1 SA spraying, and flesh firmness of both cultivars was improved significantly. The soluble solid content (SSC) of 'Kalakesai' was increased significantly, but no significant effect was found on 'Tam Dew'. The proportion of assimilates allocated to fruits was increased, while assimilates allocated to stems, leaves and seeds were reduced after BTH and SA treatments. It is concluded that BTH and SA spraying can promote the photosynthate allocation to melon fruits, and therefore increase fruit yield.
