A system for growing a plant (1) in an at least partly con-ditioned environment comprises a cultivation base (11) for receiving a culture substrate (3) with a root system (4) of the plant therein. Root tem- perature control means (12) are provided which are able and adapted to impose a predetermined root temperature on the root system, and lighting means (20, 21, 22) which are able and adapted to expose leaves of the plant to actinic artificial light. According to the invention leaf heating means are also provided, which are able and adapted to impose on the leaf of the plant a leaf temperature varying from an ambient temperature. In a method for growing the plant a carbon dioxide assimilation manage-ment of a leaf system of the plant is thus influenced, and a supply of ac-tinic light, the root temperature and the carbon dioxide assimilation man-agement are adapted to each other.
La présente invention concerne un système de culture d'une plante (1) dans un environnement au moins partiellement régulé, comprenant un support de culture (11) destinée à accueillir un substrat de culture (3) abritant le système racinaire (4) de la plante. Des moyens de régulation de la température des racines (12), conçus pour imposer une température racinaire prédéterminée au système racinaire, sont prévus, ainsi que des moyens d'éclairage (20, 21, 22) conçus pour exposer les feuilles de la plante à de la lumière artificielle actinique. Selon l'invention, des moyens de chauffage des feuilles, conçus pour imposer aux feuilles de la plante une température foliaire différente de la température ambiante, sont également prévus. Dans un procédé de culture de plantes, la gestion de l'assimilation du dioxyde de carbone par le système foliaire de la plante peut ainsi être régulée, l'apport en lumière actinique, la température racinaire et la gestion de l'assimilation du dioxyde de carbone étant adaptés les uns aux autres.
