South African Avocado Growers ’ Association Yearbook 1996. 19:70-72 The Influence of Tree and Fruit Manipulation on Avocado Tree Physiology Preliminary Results

Cincturing of Hass avocado trees in various ways and at various times, along with fruit thinning, was examined for its effect on root and xylem starch reserves and on fruit yield and fruit size.

Further work on the development of the avocado growth model is also described. This paper lists the experiments being conducted and provides some data where available
