The use of standardized plant material grown in a controlled environment can facilitate disentangling the many impacts of climate change on grapevine production and quality. Microvine is a natural gibberellic acid-insensitive mutant showing dwarfism and early, continuous flowering along the vegetative axes. Microvine was initially proposed as a plant model for genetics. Here, we examined its suitability for characterizing grapevine vegetative and reproductive growth and development patterns and responses to elevated temperature. A series of experiments was performed in the greenhouse and in growth chambers under either standard (25/15°C day/night) or contrasting (from 22/12°C to 30/25°C) thermal conditions for several weeks. Under standard conditions, temporal patterns of leaf and berry growth were similar among several phytomers along the main axis, allowing temporal growth patterns to be estimated …
