The effects of plant traits and phylogeny on soil-to-plant transfer of 99Tc

Assessments of the behaviour of (99)Tc in terrestrial environments necessitate predicting soil-to-plant transfer. An experiment with 116 plant taxa showed that (99)Tc transfer to plants was positively related to plant dry weight but negatively related to % dry matter and age at exposure. Activities of (99)Tc analysed by hierarchical ANOVA coded with an angiosperm phylogeny revealed significant effects, with 55% of the variance between species...
