SEASONAL AND DIURNAL CHANGES IN ABSCISIC ACID AND WATER RELATIONS OF APRICOT LEAVES (PRUNUS ARMENIACA L.)

B. R. LOVEYS; S. P. ROBINSON; W. J. S. DOWNTON New Phytologist 1987. doi:10.1111/j.1469-8137.1987.tb04878.x

Other claims from this paper (11)

Observation Diurnal changes in conductance and foliar ABA were small.
Observation Xylem sap ABA content was low, at 0·3 to 0·9 × 10 −4 mol m −3.
Mechanism That sap ABA concentration was too low to affect stomatal conductance.
Mechanism Xylem uptake could account for diurnal and some seasonal changes in leaf ABA.
Observation Water potential fell over the growing season.
Association Turgor stayed high as leaf osmotic potential fell.
Observation Solute accumulated between December and March.
Mechanism Sorbitol chiefly accounted for the solute increase.
Observation Capacity to synthesize ABA under zero turgor declined from November to March.
Observation Capacity to synthesize ABA under zero turgor partly recovered in April.
Mechanism ABA appears relatively unimportant for controlling stomatal conductance.
