| Abstract:
The amount of budbreak in kiwifruit, is a major yield component. Its prediction could be useful to help growers during winter pruning. The influence of the amount of winter chilling on bud burst as well as the effect of spring temperatures on the final proportionate budbreak is known. In this paper a model for bud burst simulation is proposed according to spring temperatures. Hydrogen cyanamide treatments were used to increase variability in bud burst pattern. The model parameters and threshold value for temperature were then estimated by fitting the model to data. The model appears to be very suitable to describe between-treatment variability. | |
