- Observation Bean radiostrontium uptake was linear for the first 34 hours.
- Observation Bean uptake rate sharply increased after 35 hours to 48 hours.
- Observation Immediately after soaking, 75% of radiostrontium was in bean seed coat.
- Observation Bean seed coat radioactivity decreased rapidly through day ten.
- Observation Bean cotyledon strontium proportion rose then fell after day ten.
- Observation Bean seedling axis radioactivity increased constantly.
- Observation Bean first and second leaf radioactivity rose after their appearance around day seven.
- Observation Cotton third and fourth leaves gained radioactivity at the expense of first two leaves and stems.
