![]() The model captured the variations in the timing of measured budburst, flowering and véraison over 15 seasons across New Zealand for five different varieties. The model was calibrated and tested extensively using four detailed data sets. bunch number, berry number and berry fresh weight. Weather conditions and source–sink ratio at critical developmental stages were used to determine potential grapevine yield components, e.g. The carbohydrate arbitrator was enhanced to consider both sink strength and sink priority to reflect carbohydrate reserve as a concurrent competing sink. The canopy microclimate module within APSIM Next Generation was extended to allow for row crop light interception. The simulated grapevine phenological cycle starts with the dormancy phase triggered by a critical photoperiod in autumn, and then goes through the subsequent phenophases sequentially and finally returns to dormancy for a new cycle. Modules for phenology, light interception, carbohydrate allocation, yield formation and berry composition were adapted or added into APSIM Next Generation to represent the nature of fruit-bearing vines. ![]() A new model for grapevines ( Vitis vinifera) is the first perennial fruit crop model using the Agricultural Production System sIMulator (APSIM) Next Generation framework.
