Scholarcy highlights
- Numerous studies have associated increased stomatal resistance with response to water deficit in cereals
- Leaves of IR28 became fully rolled at leaf water potential of about -22 bars; total leaf diffusive resistance was only about 4 to 5 seconds per centimeter at that stage
- Little attention has been paid to changes in leaf form or shape, as plant tissues may begin to "wilt" in similar leaf water potential ranges as those associated with stomatal response
- The leaf water potentials of IR28 measured at dawn began to deviate from controls about 12-14 days after stress treatment initiation
- Dawn and midday leaf water potentials were lower for IR28 than Kinandang Patong after day 10
- The two rice cultivars were exposed to the same initial soil and atmospheric condition, they differed markedly in their
- This may be alternately interpreted as a result of adjustment or shift in the stomatal resistance-leaf water potential relationship over the slow drying period or as an indication that rice stomata are less sensitive than some other crop species to decreasing leaf water potential
