Modelling axis organogenesis in grapevine (PMA Special Issue)

Pallas et al. construct three plant growth models to improve the modelling of grapevine development and axis organogenesis in fluctuating environments; one is based on thermal time, whilst the other two use GreenLab as the starting point. They find that potential organogenesis appears to be driven by temperature, whereas meristem activity depends on trophic competition. Water deficit is found to modify axis organogenesis independently of assimilate deficiency.
