Verbatim
e1“decreased the relative water content (RWC) and leaf water potential (LWP) in the two jute species Corchorus capsularis L. (cv. JRC 212) and C. olitorius L. (cv. JRO 632), more so in the latter”

Other claims from this paper (9)
- Intervention effect Water-deficit stress decreased relative water content and leaf water potential in both jute species.
- Intervention effect Pretreatment of seeds with 5 mM CaCl2 improved water uptake capacity.
- Intervention effect Seed pretreatment with CaCl2 did not alter stomatal movement.
- Intervention effect Foliar spraying with 0.01 mM ABA reduced transpiration through reduction of stomatal aperture.
- Intervention effect Seed treatment followed by foliar spraying additively improved water status under water-deficit stress.
- Observation Under water-deficit stress, K+ efflux from guard cells followed by stomatal closure was more rapid in C. capsularis than in C. olitorius.
- Observation Under water-deficit stress, uptake of 32P-phosphate decreased more in C. olitorius than in C. capsularis.
- Intervention effect Seed treatment with Ca2+ counteracted the decrease in phosphate uptake more markedly in C. olitorius.
- Observation The authors conclude that C. olitorius is more susceptible than C. capsularis to water-deficit stress.
