Nickel and the metabolism of urea by Lemna paucicostata Hegelm. 6746
With urea as sole nitrogen source, the addition of 5×10-5 M nickel sulfate to axenic cultures of Lemna paucicostata 6746 approximately doubles the rate of vegetative growth. Under a standardExpand

The effects of external gamma radiation from radioactive fallout on plants with special reference to crop production
This paper describes the major problems involved in attempting to predict for economically useful plants the degree of radiation damage which would arise from exposure to high level radioactiveExpand

Plant metabolic activation of 1,2-dibromoethane (EDB) to a mutagen of greater potency
Abstract The results presented in this paper suggest that EDB is capable of being converted to a mutagen by two reaction pathways, one involving a “breakdown” product in vitro and the other involvingExpand

Abstract Survival curves were determined for 12 species of woody angiosperms and 16 gymnosperms given 16-hr γ-irradiations during the early period of spring growth. The plants were scoredExpand

Influence of dose, environmental conditions and nuclear volume on survival times in several gamma-irradiated plant species.
SummaryA relationship between environmental conditions (light and temperature) and mean survival time (MST) after gamma-irradiation has been shown for plant species from six genera (ArabidopsisExpand

Correlations between nuclear characteristics, growth inhibition, and survival-curve parameters (LDn, whole plant Do and Dq) for whole-plant acute gamma-irradiation of herbaceous species.
SummaryLD10s, LD50s, LD90s, and LD100s determined for seedlings of 32 herbaceous plant species given 16-hour gamma irradiation confirmed the relationship previously found between interphaseExpand

Radiosensitivity studies with woody plants. II. Survival data for 13 species irradiated chronically for up to 8 years.
Survival curves were determined for seven species of woody angiosperms and six gymnosperms given chronic60 Co γ-exposures for up to eight years. Young plants were transplanted to the gamma field inExpand

Woody Plants: Changes in Survival in Response to Long-Term (8 Years) Chronic Gamma Irradiation
The number of plant deaths which occurred over 8 years of chronic gamma irradiation (20 hours/day) of 11 species of woody plants indicated a decline in the rate of death with increasing exposureExpand

Effects of X- and gamma radiation on anthocyanin content in leaves of Rumex and other plant genera
Abstract The concentration of anthocyanin pigments in the leaves of seedlings of Rumex crispus L., R. hydrolapathum Huds. and R. sanguineus L. was found to increase following exposure to X-rays orExpand
