Abstract : Chiin Hwang mango fruits were collected periodically from 26 June (93 days after anthesis) to 24 August (152 days after anthesis) to determine fruit weight, volume and specific gravity as well as the relationship between degree of maturity, sugar content and the extent of mesocarp disorder [breakdown?]. Results indicated fruit weight and volume increased as fruits developed. The specific gravity was closely related to fruit maturity, and the former tended to exceed 1.00 by 121 days after flowering. Those fruits picked on day 93 had a soluble solids content of 11.2% and reached 15.2% by 152 days after flowering. The fruit disorder worsened at later stages of ripening; it reached was 60% by 135 days after flowering, as compared with 15% on day 121, and a close relationship was found between specific gravity and the extent of the fruit disorder or sugar content. It is suggested that fruits should be harvested on day 120 at a specific gravity index of 1.01 in order to maintain fruit quality, yield and to solve the problem of uneven ripening.
