The effects of CCC on the 32 P amounts absorbed by cotton seedlings were studied. CCC was applied to the seedlings either as spray or as addition to the nutrient solution in concentrations of 0, 25, 50, 100 and 200 mg/1. 32 P was added to the medium as KH 2 32 P O 4 in the concentration of 40 μCi/50 ml. During the experimental period, no morphological changes were observed. The total 32 P uptake was inhibited in CCC treated seedlings. The application of CCC, both as spray and as addition to the medium, led to an accumulation of 32 P in stem, but to a decrease in root. The leaves showed different responses to different methods of application; spraying increased, while an addition of CCC to the medium decerases the 32 P content in the leaves. It is concluded that CCC inhibits 32 P uptake, whereas it ac accelerates the 32 P translocation from root to the aerial parts .
