Effects of pollen sources on the quality of nuts borne by pecan cultivars Kiowa and Barton. [original article]. [Efeitos de fontes de pólen na qualidade de castanhas produzidas por cultivares de noz-pecã Kiowa e Barton].

ABSTRACT:Selection of pecan cultivars and their pollinizers is essential to reach maximum potential of production. Synchrony of blooming periods of cultivars may not be enough to ensure nut quality because of the xenia effect. This study aimed at evaluating effects of different pollinizers on dimensions and yields of fruit borne by cultivars Kiowa and Barton. Both cultivars were submitted to six treatments. Kiowa:no pollination, free pollination, self-pollination and pollination controlled by pollen from cultivars Cape Fear, Pawnee and Desirable.
