Abstract

The introduction describes the geographical distribution of the mango, and gives new data on its occurrence on Java and Madura, and calculates the financial profits for the population. The observations on flowering are described, which may contribute to the knowledge on flowers and inflorescences in general, and may serve as guides in crossing experiments with mango varieties. The chapter on yields contains facts of value for trade and in crossing techniques.

Results of crossing experiments are discussed. Two varieties could set fruit without wind and insects; another one was closely dependent on wind. The preliminary fruit set was 5 to 24 times as large as final yield. Flies were the only regular visitors, although not in large numbers. There were no wild bees in Pasuruan.

Introducing hives each of 13,000 to 15,000 bees per 10 trees into the mango gardens showed that some mango varieties were frequently visited, others less so. The commercial varieties attracted many (or fairly many) bees. Although no definitive conclusions could be drawn, an increased yield of 23 fruits per tree would already meet the expenses of bee-keeping. For peasant culture the profits would be even greater.
