Plant recovery following prolonged drought in a shortgrass steppe

摘要: Abstract The recovery cycle of Bouteloua gracilis (H.B.K.) Griffiths after a 56-day drying has been monitored to assess the effect prolonged drought upon ability different plant processes respond an increase in water availability. Leaf potential before dawn and at noon recovered rapidly indicating that previous had minimal these variables. conductances during first seven days were considerably lower than values estimated by simple model, profound on behavior stomata. Since leaf conductance represents major control photosynthesis cycles we suggested ecological significance droughts effects lies their impact carbon assimilation.
