Abstract:

In order to understand the relationship between the growth characters of autumn flushes and quality of bearing shoots and the flowering rate of Mangifera indica ‘Zill’, methods of investigation and statistics were applied to analyze the relationship between the first autumn flush, second autumn flush and quality of bearing shoots and the flowering rate of terminal shoots and panicle size. The result of the study indicated that the diameter and the leave area of the first autumn flush had remarkable effects on the diameter and the leave area of the second autumn flush respectively. The leave number and the leave area of second autumn flush increased as the diameter and the length of the second autumn flush increased. There was negative relationship between the flowering rate of terminal shoots and the diameter of bearing shoots. The flowering rate of terminal shoots decreased as the diameter of the bearing shoot increased. A result of 80%-85% of flowering rate for terminal shoots was obtained when the diameters of bearing shoots were about 0.48-0.51 cm. The volume of the panicle was most close to the diameter of bearing shoots and markedly correlated to the length, the leave number and the leave area of bearing shoots.
