Other claims from this paper (14)
- Observation Globoid element composition changed markedly during early seedling growth in Cucurbita cotyledons.
- Observation In both species, globoid K decreased markedly regardless of light and mineral nutrient conditions.
- Observation In both species, globoid Mn and Zn generally increased regardless of light and mineral nutrient conditions.
- Observation In both species, globoid P remained relatively constant regardless of light and mineral nutrient conditions.
- Mechanism Differences in globoid composition changes between the two species could be attributed, at least in part, to differences in the Ca content of mature dry embryos.
- Observation In C. andreana, which had a higher initial Ca content, globoid Ca content increased largely during seedling growth.
- Observation In C. andreana, globoid Mn did not increase significantly during seedling growth.
- Observation In C. maxima, globoid Ca increased only slightly.
- Observation In C. maxima, globoid Fe, Zn and Mn increased much more than in C. andreana.
- Intervention effect Light conditions alone did not significantly influence the changes in globoid composition.
- Intervention effect Light combined with mineral nutrients produced a more rapid degradation of globoids in later stages of growth.
- Intervention effect Mineral nutrient conditions affected mostly the elements that were initially present in large amounts in globoids.
- Observation Very large, globoid-like particles were present in some later-stage samples of both species under every growth condition.
- Observation The large particles had element compositions consistent with being composed of phytate.
