Other claims from this paper (16)

Observation Unstressed common bean calli had higher osmotic potential and relative growth rate than tepary calli.
Observation Unstressed common bean calli had lower dry matter percentage than tepary calli.
Intervention effect Water stress did not affect measured parameters for common bean leaf callus or tepary leaf and root calli.
Intervention effect Common bean root callus osmotic potential decreased under water stress and remained low after recovery.
Intervention effect Common bean root callus relative growth rate decreased.
Intervention effect Common bean root callus dry matter increased.
Intervention effect Stress significantly reduced leaf, stem and root dry mass and leaf area in both bean types.
Observation Mass reduction was especially high in common bean stem, leaf and root.
Observation Tepary roots penetrated deeper in soil.
Intervention effect Common bean root depth did not significantly change with drought.
Observation Substantial common bean root mass occurred in the upper 10 to 20 cm of soil.
Observation Common bean had higher stomatal conductance and transpiration than tepary under both watering regimes.
