Preliminary aspects of the floral biology of Anacardium occidentale L. (Cashew) in Maracaibo’s plain

Abstract:

The preliminary aspects of the floral biology of Anacardium occidentale L. (cashew) were evaluated in red and yellow cultivars and clones (Embrapa CCP-1001 and Embrapa CCP-76). The methodology of Raimundez and Hokche was used. Hermaphrodite and staminate flowers, presented five green and pubescent sepals and five white petals when they are newly opened and then are pink. The gynoecium had a sunilocular and uniovular ovary and the androecium had seven small anthers and one anther longer than the rest, all ditecas. The anthesis of the staminate flowers was between 1:00-3:00 pm and the hermaphrodite flowers were observed between 10:00 am and 03:00 pm. The pollen is simple convex and reticulated. The floral biology is essential to the agronomic management of the species.
