Longan (Dimocarpus longan Lour.), litchi (Litchi chinensis Sonn.), and rambutan (Nephelium lappaceum L.) are typical subtropical fruits opulently cultivated in southern China, which are popular for customer to buy in summer (from June to August).
It would also be meaningful to understand whether antioxidant levels of litchi, longan, and rambutan are altered immediately after UV treatment or, gradually, controlled by gene expression.
Litchi, longan, and rambutan have similar structure: outer hull (exocarp) protects edible pulp (mesocarp) containing internal core stone (endocarp and seed) .
Hennessey and Gould repeated the procedure with Kohala longans - and again with top-quality longans and lychees from the packinghouse.
Using guava as a control, Hennessey tried one more test: covering bunches of longans and lychees on the trees with pollination bags holding five fertile Caribbean fruit flies.
After 24 hours, there was no evidence that the flies had infested the longans or lychees, but they had attacked the guavas.
Longans are very much like litchis, except smaller, coarser textured, not quite as flavorful, and often somewhat less expensive.

Recite them quickly and they sound like a Gilbert and Sullivan patter song: litchi, longan, mangosteen, rambutan.
Moreover, the postharvest quality of the longan fruit revealed no difference over time; plus the percentage of fruit drop was only 5.2%, when compared with the control was 5.8% and other treatments ranged from 5.5 to 5.9%.

The longan fruit (Dimocarpus longan Lour.) is grown commercially in many countries, including China, Thailand, Taiwan, India and Vietnam (Jiang et al., 2002).
