Abstract:

Absorption, translocation, and metabolism of C14-labeled tetramine were investigated in Douglas-fir, orchard grass, and blackberry. Applications were made to the foliage and in nutrient culture solutions under controlled conditions, and the tracer was followed in treated plants with autoradiography and counting techniques. C14-labeled tetramine was absorbed from nutrient solution by roots of all three species. Transport occurred via the transpiration stream, and translocation was slowest in Douglas-fir. After uptake by roots and deposition in plant tissues, the tracer did not recirculate within the plants. Immobility (nonsystemic properties) of the chemical was also demonstrated by lack of downward movement after foliar applications. C14-labeled tetramine was metabolized in the plants, and degradation was highest in orchard grass and lowest in Douglas-fir. Tetramine's toxicity, possible hazards in its use, and its nonsystemic properties suggest that use of the chemical to protect tree seedlings from animals does not look promising.
