It is of interest to learn whether various Vitis vinifera cultivars are similar to Gordo in the response of fruitfulness to factors of the environment and this paper describes growth cabinet experiments done to provide some information.
It is concluded that there is variation between Vitis vinifera cultivars in the way their fruitfulness responds to environment. Results suggest that all cultivars may perform well with high temperature and high light intensity, but fewer may be able to perform satisfactorily with low temperature and low light intensity.
