Abstract : An experiment was conducted to study the linear correlations between the bisexual flower percentage of mango cv. Tainong 1 and temperature and humidity variants during and before flowering. Tainong 1 had a relatively high percentage of bisexual flowers, and the percentage of bisexual flowers increased as the temperature increased. The morphological differentiation of flower organs began approximately 30 days before blossom (DBB) and ended 5 DBB. The percentage of bisexual flower had a significant and positive linear correlation with the average diurnal highest temperature, the average diurnal temperature, the average diurnal lowest temperature and the accumulated temperature during 6 to 30 DBB. From 26 to 30 DBB, the temperature and humidity was vital to the formation of bisexual flowers, where relatively higher temperature and suitable humidity would benefit the formation. During 16-20 DBB, the percentage of bisexual flowers increased with higher average diurnal humidity.
