Effects of some growth regulators on the CO2 exchange of leaves


, : Effects of some growth regulators on the CO2 exchange of leaves. Acta Horticulturae (34): 55-58

Daminozide and chlormequat decreased whereas GA increased apparent photosynthesis (APS) in treated leaves of young apple trees and bean plants, especially when APS was expressed per unit weight of chlorophyll. As these growth regulators modified light respiration in the same direction as APS, true photosynthesis was really changed.

Mature chrysanthemum leaves with petioles were stood for 6 h in IBA or coumarin at 1 to 500 mg/l or in water (control) and were then rooted in sand. The IBA concentration which stimulated rooting (100 mg/l) lowered the transpiration rate, increase...
