Figs, Caprifigs, and Caprification

A comprehensive discussion of the diseases of the fruit of the fig should take into consideration its structural peculiarities. Eisen(10), (11) discusses exhaustively the morphology and structure of this fruit. Condit (5) gives a brief discussion of the fig fruit and its structure.

The fig is a nearly closed, more or less hollow receptacle, the inner walls of which are lined by the flowers when immature and by the fruit when ripe. It is not, therefore, a fruit in the strict botanical sense of the word but an aggregation of fruits lining the cavity of a hollow receptacle, technically a synconium, with an opening at the center of the flattened, distal end, which is closed during the early stages by a system of overlapping bracts. As the fig begins to ripen and soften these bracts or scales loosen and an opening is formed, the diameter of which varies from 2 to 10 mm., according to the variety of fig. This opening is usually referred to as the “eye” of the fig. In the ripe fig the wall of the receptacle to which the flowers are attached is called “the meat,” and the aggregation of mature florets “the pulp.” Figure 1 shows the internal appearance of the receptacle when split longitudinally. The flowers of the fig vary with the variety, the sex, and the crop.
