Other claims from this paper (19)
- Observation The main dry matter deposition site shifted from seed coat to kernel between 30 and 70 DAF.
- Observation Pericarp water content remained high through most development but declined rapidly after 130 DAF.
- Observation Water content of the seed coat and kernel declined over 30–110 DAF.
- Observation Potassium and magnesium deposition centers moved to the kernel between 70 and 80 DAF.
- Observation Calcium deposition moved from pericarp to seed coat to kernel and back to pericarp.
- Observation Seed coat sucrose-to-hexose ratio increased between 30 and 80 DAF.
- Association Seed coat sucrose-to-hexose ratio correlated with soluble sugar, starch and protein accumulation.
- Observation Pericarp sucrose-to-hexose ratio peaked at 40 and 100 DAF.
- Association Pericarp sucrose-to-hexose peaks correlated with reserve deposition in the following 20–30 days.
- Observation Pericarp and seed coat chlorophyll concentration fell after 30 DAF.
- Association Maternal fruit tissue chlorophyll b/a had a significant positive linear relation with soluble sugar concentration.
- Association Potassium content correlated positively with starch content (ρ = 0.673, p = 0.0164).
- Association Potassium content correlated positively with oil content (ρ = 0.915, p = 0.000203).
- Association Potassium content correlated positively with protein content (ρ = 0.814, p = 0.00128).
- Association Magnesium concentration correlated positively with starch content (ρ = 0.705, p = 0.0104).
- Association Magnesium concentration correlated positively with oil content (ρ = 0.913, p = 0.000228).
- Association Magnesium concentration correlated positively with protein content (ρ = 0.896, p = 0.0000786).
- Association Calcium content correlated significantly with soluble sugar content (ρ = 0.585, p = 0.0457).
- Mechanism The maternal pericarp and seed coat may buffer nutrients between the mother tree and kernel.
