Abstract Growth rates of individual leaves attached to sunflower (Helianthus annuus) plants were measured experimentally under different levels of environmental productivity, modified by irradiance and nutrient conditions. The unfolding rate and final area of an individual leaf increased with increasing environmental productivity. The final area of an individual leaf also varied according to differences in leaf order. The declining pattern of relative leaf area growth rate (RLGR) varied with environmental productivity; leaves in a productive environment had a longer period of high sustained initial RLGR than leaves in a less productive environment. However, maximum RLGR was hardly influenced by leaf order or environmental factors such as irradiance and mineral nutrition.
