Conteúdo: | Diurnal fluctuations in fruit diameter and leaf thickness of Calamondin orange trees were measured and related to transpiration from leaves and to internal redistribution of water from fruits to leaves. While trees were well irrigated, leaf thickness began to decline daily around sunrise and to increase in mid-afternoon. Dailuy shrinkage and expansion of fruits later than in leaves. The lag in responde of leaf thickness changes in vapour pressure deficit of the air was 1 or 2 hours, wheras the lag in response of fruit diameter was 3 or 4 hours. During imposed droughts, daily shrinkage of fruit anf leaves continued until later in the day when trees were well irrigated. Moreover, during a drought, expansionof the tissues at night occurred at a much slower rate than during periods of daily irrigation, or expansion did not occur at all. Movement of water from fruits to leaves on excised branches was indicated by the higher percentage moisture content of leaves on branches bearing fruit than of leaves on branches without fruits.
