Air humidity differentially affected the foliar absorption of 33P and 86Rb by Chrysanthemum morifolium 'Giant # 4 Indianapolis White' and Pilea cardierei. As the relative humidity increased from 47 to 80% in most cases, there was in increase in uptake. Further raising of humidity to 92% increased uptake of Rb and P by Chrysanthemum leaves only when guttation did not occure . Air humidity influenced most strongly the uptake of calcium phosphate probably due to its low solubility
