Title
Effects of Gamma Radiation on Salix nigra Marsh Cuttings
Roy Z. Gehring Journal of the Arkansas Academy of Science 1985
Other claims from this paper (8)
- Intervention effect Low doses of ionizing radiation apparently stimulated growth of Salix nigra cuttings.
- Intervention effect Higher radiation doses progressively retarded growth of Salix nigra cuttings.
- Association Staminate catkin growth was inversely proportional to total exposure dose.
- Intervention effect Pollen grain viability increased with gamma radiation up to 100 r.
- Observation Exposure to 10 Kr gamma radiation caused 100% mortality of the cuttings.
- Observation The highest growth rate at ninety days occurred at the highest surviving exposure dose.
- Observation Recovery of the surviving fraction of irradiated cuttings was indicated by growth rates at different intervals.
- Association Total RNA and protein concentrations were sensitive even to the lowest exposure doses.
