Abstract
Abstract Eight different light treatments did not affect shoot length, leaf number, or total leaf area of young ‘Red Yorking’ apple ( Malus pumila Mill.) trees grown in a greenhouse. Dry weights of leaves and stems were suppressed by 80% shade. Net photosynthesis (Pn), dark respiration (Rd), and specific leaf weight (SLW) were higher in sun than in shade leaves and adaptations in all 3 parameters occurred as a result of changing light conditions, even after leaf expansion had ceased.
