Synopsis

Excerpt from The Pollination of the Mango

Attacking the problem of mango sterility from several angles, as herein outlined, it has been possible to eliminate several factors here tofore generally believed to have some bearing on the question. Apparently the difficulty is not due to any morphological defect in the pollen or to defects in the mechanism of pollination. By the ex clusion of these factors and from the observation of trees in Florida and other regions during several seasons, the conclusion has been reached that the problem is a physiological one, connected with nutritional conditions as in?uenced by changes in soil moisture and food supply, principally the former. While such factors as lack of pollinating insects and loss of pollen through excessive rains may at times have an injurious effect upon the mango crop,'-it seems safe to assert that the question of pollination is of comparatively little importance from a practical standpoint. Experiments have been undertaken, with the cooperation of Prof. E. 'j. Kraus, to test the practicability of inducing the formation of ?ower buds through ringing, girdling, and banding the limbs with wire. The work of Prof. Kraus at the Oregon Agricultural Experiment Station 1 with pomaceous fruits has sug gested various methods of this nature, and the results of these experi ments with the mango will be watched with interest. At various times excellent results have been reported from ringing and girdling the mango, but systematically arranged experiments along. This line have not been undertaken. It may be that ringing the mango should become a standard orchard practice, but it is'hoped that from the present experiments it will be possible to learn more concerning the physiology of fruit setting in the mango and thereby establish other orchard practices, such as cultivation or pruning, best adapted to insure commercial crops of fruit. In Cuban experiments, fertilizers very rich in potash have yielded good results in the way of increased fruit production. It is to be hoped that such experiments as these will bring to light a practicable method of encouraging the formation of fruit buds on soils or under climatic conditions which normally tend to produce vegetative growth to the exclusion of reproduction.
