| Abstract:
Seasonal aspects of the growth of mango trees were studied at Gin Gin (latitude 31°20'S), 100 kms north of Perth from July 1988 to May 1989. The trees were growing on sand on a north-westerly rise approximately 30 kms from the coast. Observations included records of shoot activity and the probability of flower development from shoot carrying 0–4 previous flushes of growth. In 1988 season, 70% of all shoots produced one or more flushes of vegetative growth while 30% remained dormant. Inflorescence emergence began in July and reached a maximum in late September to early October. An average of 72% of all shoots, both flushing and dormant, producing an inflorescence. Shoots with a zero flush count had a probability of 0.56 of flowering and, on average, produced 2.2 inflorescences per terminal bud whorl, while shoots with 1–4 flushes had a probability of flowering of 0.85 but produced a single inflorescence only. Vegetative growth occurred mainly during summer and reached a maximum during February. In 1989 fruit harvesting occurred from early March to mid April. | |
