extensively and reports are conflicting. It takes three or four months for the fertilized flowers to develop into mature fruits.
As has been mentioned, this fruit is not well adapted for shipment to distant markets, nor has it a long "shelf life." The carpels cohere so loosely, especially as the fruit softens, that careful handling is required. After harvesting, it is difficult to keep sugar-apples in good condition more than four or five days.
The culture of this tree is so simple that horticultural attention has been given it. Most sugar-apple trees are seedlings, which come into bearing at the age of 3 or 4 years, but are short-lived and usually die when 20 to 30 years old. Pruning old branches to leave younger, more vigorous ones may prolong productiveness. Trees planted in orchard form should be spaced 4 to 6 m. apart. On poor soils fertilizers will, of course, encourage growth and yield. While the sugar-apple withstands drought remarkably well, in dry climates irrigation results in better growth and more fruit.
The horticultural future of the sugar-apple lies in the selection of superior seedlings and their propagation by vegetative means. Studies by horticulturists of the vast seedling populations in India have shown as much variation in size, shape, and surface characters of sugar-apples as has long been known in cherimoyas, and an even greater range in fruit color. Occasionally they are almost purple. Seedlings in India sometimes bear fruits weighing almost a kilogram. A seedless form was found in Cuba some years ago, but the fruits were too small to be of value. Budding and veneer grafting are easily done on sugar-apples, using as stocks seedlings of this species or those of the custard-apple.
In general, the same pests which attack the cherimoya can be expected on sugar-apples. Little attention has been given this subject in tropical America.
