Fruit developmnt rule of two Chinensis Actinidia cultivars ‘Fengyue' and'‘Cuiyu’

The fruit development rules of two Chinensis Actinidia cultivars were studied in this paper. ‘Fengyue' has thedevelopment phase named comparatively stable period, slow increase period, rapid increase period and stagnatingincrease period. Fruit firmness change exhibits two periods, i.e. slowly declining period and rapidly declining period.There is an obvious corresponding relation between the changes of fruit firmness and the soluble solids content, i.e. therapidly declining time of fruit firmness corresponds with the rapidly increasing time of soluble solids content. According toto early November, respectively.
