Abstract
Although Leucospermum cultivars Tango, Succession I, Scarlet Ribbon, and High Gold have been cultivated in Azores for approximately a decade, no studies have been conducted to assess their growth and developmental patterns.
During the 2006–2007 growing season, fortnightly stem length measurements and developmental stages were recorded in farms located on most of Terceira Islands production regions.
In this presentation we report the growth and developmental patterns of these four cultivars.
We relate these data with environmental conditions and assess the feasibility of thermal and photo-thermal models to predict the average harvest date of these genotypes.
We conclude that Leucospermum average harvest date can be predicted with thermal and photo-thermal models, although predictability varies among the cultivars tested in this study.
