ABSTRACT Correlations between seed number and fruit weight, and between seed distribution and fruit shape were established for Chinese gooseberry (Actinidia chinensis Planch.) fruit. Ovaries containing few seeds develop into small fruit, and various growth regulators, either alone or in combination, were applied to fruitlets containing few seeds in an attempt to increase fruit size. In general, auxins (2.4-dichloroph enoxyacetic acid. 2.4.S-trichlorop henoxyacetic acid. p-naphthoxyace tic acid. indoleacetylasp artate). gibberellins (GA:!, GAf-7). and cytokinins (6-benzylamino purine. zeatin) when applied alone did not stimulate fruit development; nor did combinations of auxin + gibberellin. and gibberellin + cytokinin. However, auxin (2,4-D or 2A.S-T) + 6-benzylaminop urine and auxin + cytokinin + gibberellin markedly
