Other claims from this paper (9)
- Observation Five of eighteen peanut genotypes lacked hairs on roots and gynophores.
- Observation Other peanut genotypes developed root and gynophore hairs with variable density.
- Association Root hair presence and density coincided with gynophore hair presence and density.
- Observation Final root phosphorus uptake did not differ among peanut genotypes.
- Mechanism A hairless peanut genotype maintained phosphorus uptake through a large root system.
- Observation Wasedairyu roots extracted phosphorus three times as efficiently from deficient soil.
- Observation Gynophore phosphorus uptake contributed about 20% to Wasedairyu total uptake.
- Observation Gynophore phosphorus uptake contributed insignificant amounts in the other genotypes.
- Mechanism Hairs combined with a large root system could increase peanut tolerance to phosphorus deficiency.
