Development and maturation of the apple of early dwarf cashew tree CCP-76.

 

In January 1995, cashews (nut + apple) were harvested from clone CCP-76 at Pacajus, Ceara, Brazil, and separated based on apple skin colour into 7 developmental stages: (1) green with green nut, (2) green with ripe dry nut, (3) light green, (4) some yellow colour, (5) yellow changing to orange, (6) light orange, and (7) deep orange. The following characteristics of the apple were evaluated: weight, length, upper and lower diameter, pH, and contents of soluble solids (SS), reducing sugars, titratable acidity (TA), vitamin C [ascorbic acid], tannins and chlorophyll. After full development of the nut, the apple increased significantly in size. Best eating quality (highest SS and reducing sugars contents, lowest TA and highest SS:TA ratio) was associated with stage 7. Total chlorophyll decreased and vitamin C content increased during maturation. Tannins did not change significantly and pH also remained stable. It is concluded that clone CCP-76 produces cashew apples of good eating quality both for f

resh consumption and juice processing.
