In order to understand the microclimatal factors affecting the produce of mango, the ratio of fruiting has been investigated for two years since 1992 at Yu-Ching of Tainan, San-Ti-Men and Chun-Jih of Pingtung county, and twenty, ten, fifteen, respectively, years old of mango trees was used in this experiment. The varieties are ‘Irwin’ at Yu-Ching and Chun-Jih, ‘Native’ at San-Ti-Men. The results indicated that the cold waves that occurred during November and December should be responsible for low fruiting ratio of mango at San-Ti-Men. Nevertheless, the cold waves during January and February should be for Chun-Jih experimental fields. The cold waves devastated flowers and fruits which at marble-sized growth stage or younger. At Yu-Ching experimental field, however, cold waves scarcely occurred during mango flowering and fruit-setting season, because farmer took terminal flower off to obtain auxiliary flower bud that developed and flowered during April. Owing to heavy rainfall and/or long rainy periods cause anthracnose and reduce the effectiveness of pollen insects. So rainfall and rainy periods during April and May might be key factors for producing mango in this field.
