The sav3 and phyB mutations reduce SAS responses to crowding at low, but not at high canopy cover. Variations leaf angle and lamina-to-petiole length ratio (L:P) of Arabidopsis plants were measured in response to crowding (increased canopy density) in a density gradient experiment. The experiment was carried out in a glasshouse, under natural radiation during the autumn in Buenos Aires (see Experimental procedures for details). There were 4 trays for each genotype and canopy density combination; the 9 central plants were measured in each tray. Bars indicate ±1 S.E (n=4). (a-b) Measurements of leaf angle and leaf morphology 25 d after germination. (c-d) Measurements of leaf angle and leaf morphology 45 d after germination.
