Abstract

Chempedak and terap are common village fruit trees in Sarawak east Malaysia and Borneo. The terap is cultivated locally in Borneo and the Philippines while the chempedak is commonly cultivated throughout Southeast Asia. Wild trees of these species occur in the secondary and primary forests of Sarawak. Chempedak fruits are highly variable. There is no consistent difference between wild and cultivated trees in size or nutritional content of the fruit or characters of the leaves twigs and male inflorescences. Cultivated terap fruits and male inflorescences are several times larger than those found in wild treees which is an indication that the cultivated trees are genetically distinct from wild trees. Individual fruit characters generally vary independently of each other but total fruit weight is strongly correlated with the weight of fruit flesh and weight of seed per fruit. A close developmental relationship is apparent among certain pairs of fruit characters such as the weight of a single seed and a single fleshy perianth and the percentage of the water content. The flesh of moraceae fruit is low in fats and protein but generally high in carbohydrates content. The seeds are higher in protein and fat contents than the flesh. Artocarpus species are more seasonal in their reproductive behavior than fig species. Artocarpus species differ in the time required for fruit maturation. The terap fruits take about ten weeks and chempedak fruits take about 12 weeks to mature
