This is a preliminary hydroponic study to test willow sensitivity to silver nitrate, a highly toxic chemical compound. We grew willow cuttings for a period of three weeks in the presence of increasing AgNO(3) concentrations and assessed the response in terms of growth and physiology. We found that AgNO(3) is generally extremely harmful to willow. AgNO(3) concentration as high as 0.027 muM may result in a significant reduction of biomass productivity and a decrease in stomatal conductance over the first week of exposure. However, willows seem able to adapt to high AgNO(3) concentrations on a longer timeline.

Abstract
This is a preliminary hydroponic study to test willow sensitivity to silver nitrate, a highly toxic chemical compound. We grew willow cuttings for a period of three weeks in the presence of increasing AgNO(3) concentrations and assessed the response in terms of growth and physiology. We found that AgNO(3) is generally extremely harmful to willow. AgNO(3) concentration as high as 0.027 muM may result in a significant reduction of biomass productivity and a decrease in stomatal conductance over the first week of exposure. However, willows seem able to adapt to high AgNO(3) concentrations on a longer timeline.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
