Other claims from this paper (8)
- Association Vigna glabrescens had more gradual stomatal closure as drought intensified.
- Observation Vigna glabrescens maintained significantly higher stomatal conductance than other genotypes.
- Observation Vigna glabrescens maintained significantly higher photosynthetic activity than other genotypes.
- Observation Only Vigna glabrescens accumulated significant proline under moderate water deficit.
- Observation Vigna glabrescens had lower osmotic potential.
- Observation The three Vigna unguiculata cultivars had similar stomatal control under increasing water deficit.
- Observation Vigna glabrescens Pmax remained unaffected through the drought.
- Mechanism The authors attribute Vigna glabrescens PN decline mainly to stomatal closure.
