Studies on Fruit Development Of Seed-wilted Longan——Correlative Analysis on Fruit Growing Type and lts Characters

The research results showed that the fresh-weight increase of Min Jiao 64-1, Min Jiao 64-2and Baihe Lonyan fruits and their seperate parts appeared to be a single S-type curve, The dynamic change of soluble solid content was Min Jiao 64-1and Min Jiao 64-2 appeared a double Stype curve wbereas Baihe Lonyan appeared a single S-type curve.The correlative and path analysis on the relationship between fruit development with seed, pericarp and aril were undertaken.It was found that, similar to Litchi.the fruit development of seed-wilted lonyan was affected in properorder by seed-pericarp-aril,and the effect of pericarp matter on aril just like the one of ball skin on its bladder.
