Growth of Atriplex Halimus L. in Sodium Chloride Salinated Culture Solutions as Affected by The Relative Humidity of the Air

Abstract

A. halimus plants were grown in saline nutrient solution (Knop's), in growth chambers, under two different conditions of relative humidity of the air: 27 � 3 % (dry) and 65�3% (humid). All other climatic factors (temperature, illumination, etc.) were identical. Relative humidity was programmed to remain constant irrespective of day and night temperature changes. The salinity range was 0 to -20 atm NaCl.
