Wpływ IAA i GA3 na natężenie fotosyntezy, oddychania i transpiracji siewek pszenicy jarej i kukurydzy w warunkach niedostatku wody w glebie [The effect of IAA and GA3 on photosynthesis, respiration and transpiration of spring wheat and corn seedlings under conditions of insufficient water in the soil]

W. Nowakowski, Grażyna Lubańska

Abstract


It was found that IAA and GA3 distinctly increase the intensity of photosynthesis of the grain seedlings under 30% capillary water capacity. At 60% of capillary water capacity this effect is smaller. The effect of the applied substances on respiration and transpiration is pronounced in spring wheat and only slight in corn.
