Leaf growth and stomatal sensitivity after water stress relief and its relation to xylem sap absicisic acid
Responses of pepper seedlings to rewatering after being subjected to 5 and 11 days of gradual water stress were investigated. Leaf growth, water relations, stomata conductance and xylem sap ABA in these plants were compared with plants grown under continuous well watered and stressed conditions. L...

| description | Responses of pepper seedlings to rewatering after being subjected to 5 and 11 days of gradual water stress were
investigated. Leaf growth, water relations, stomata conductance and xylem sap ABA in these plants were
compared with plants grown under continuous well watered and stressed conditions. Leaf water potential
returned to the control values immediately after rewatering but the stomatal conductance of stressed plants did not
recover until 48h after rewatering. The concentration of ABA in the xylem sap in the pre-treated stress plants
returned to similar values to the control 6h after rewatering. After rewatering, leaf growth of plants pre-treated with 11d of water stress was rapid and exceeded growth of continuously well watered plants. The plants grown
under continuous water deficit show reductions in leaf growth, stomata conductance and increase in xylem sap
ABA. |
