The knowledge of phenological stages and nut development of macadamia trees is essential for the adequate management of the plant, aiming pollination studies and controlled crossing between cultivars, needed in breeding programs. The phenological temporal patterns of seven macadamia cultivars selected at the Instituto Agronômico (IAC) were researched in the collection of cultivars. Small variations were verified among the initial phenological stages, from emission of the racemes up to the swollen flower bud stage. The complete cycle, from the flower bud emission to the fruit dropping took 253 days. The phenological stages - mature fruits and fruit dropping - occurred from the second tenth of February to the end of March.
