The performance of the grapevine in a regime of changing seasons

摘要

This article presents the author's observations based on a study of vine behaviour in relation to seasonal temperature at his own vineyards and in other different situations, both cool and warm. The figures presented are original to the author. Hourly temperature data for this study was sourced from the Australian Bureau of Meteorology. The article: 1. describes a methodology for precise analysis of site thermal relations from hourly temperature data. 2. relates site thermal relations to plant productivity and ripening date. 3. presents new concepts relating to the interaction between site, vine and cultural circumstances that are useful in the quest to secure fruit with superior flavour for wine making purposes.
