Title

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.

Title

Studies on the Effects of Relative Humidity of the Atmosphere upon the Growth and Physiology of Rice Plant : V. Influence of humidity on senescence of rice plant leaves

Other claims from this paper (8)

Intervention effect Chlorophyll content of the third leaf decreased faster under low humidity than under high humidity.
Intervention effect Rice plants grown under low humidity had lower water content than those under high humidity.
Association Decrease of water content in rice leaves was followed by decrease of chlorophyll content.
Intervention effect High humidity increased the leaf area of rice plants.
Intervention effect High humidity accelerated leaf emergence in rice plants.
Mechanism Products of photosynthesis in the third leaf were necessary for young leaf emergence.
Association More materials translocated from the third leaf were associated with faster senescence of that leaf.
Intervention effect High humidity delayed third-leaf senescence in rice, which the authors link to promoted growth.
