Studies on self- and cross-pollination of olives under varying temperature conditions

Abstract

Investigations with Ascolano, Manzanillo, and Sevillano olive varieties show that chances of fertilization and fruit set are much greater after cross-pollination than after self-pollination. Pollen tube growth usually is faster following cross-pollination than after self-pollination and more pollen tubes can reach embryo sacs before the sacs degenerate.
