A comparative study of the Kadota, Calimyrna, Adriatic and Mission varieties of fig with regard to fruiting habit, internodal length, leaf area, and diameter of fruit at maturity disclosed the following:
1. In all varieties there was a progressive increase in the percentage of nodes producing fruit from the basal-most to the fourth node. Maximum fruiting occurred on nodes 3, 4, 5, and 6 depending upon the variety. Beyond the most fruitful median nodes and toward the terminal ends of the shoots, there was a progressive decrease in the percentage of fruitful nodes.
2. In the Kadota and Calimyrna varieties, the median nodes on the shoot produced the highest percentage of double figs.
3. In the Calimyrna, the variety requiring cross-pollination before the fruit will set, the highest per cent fruit set resulted on the median nodes of the shoots.
4. Internodal length progressively increased from the distal to the median portions of the shoot and then progressively decreased in the terminal region.
5. Average leaf area progressively increased from the first to the third node in all varieties, after which a progressive decrease occurred to the terminal most or nineth node.
6. With the exception of the Calimyrna variety, there was a progressive decrease in fruit diam3ter at maturity from the first to the nineth node. Fruit diameter in the Calimyrna followed a pattern particularly like that of leaf area.
