Carbohydrate and phenological cycling as management tools for avocado orchards

The reason for low average avocado yields are summarized, and it is concluded that the grower will have to increase yield ha -1 to remain competitive. The concept of the phenological growth model is explained and its value to understanding orchard management discussed. Carbohydrates are sources of energy for growth and respiration and components such as starch, undergo seasonal changes which can be related to tree performance. The writers motivate an international research programme on these concepts which is currently underway.
