Other claims from this paper (9)
- Observation Internode growth occupied fewer times and node positions than leaf and tendril growth.
- Intervention effect Water deficits caused initial inhibition and final cessation at identical times in internodes, leaves and tendrils.
- Observation At low water potential, growth inhibition was similar among grapevine organs.
- Intervention effect Water deficits left relative growth partitioning among internodes, leaves and tendrils unaltered.
- Observation Growth inhibition began at soil water potential of -0.065 MPa.
- Observation Growth ceased completely at soil water potential of -0.54 MPa.
- Intervention effect Water deficits reduced the shoot region in which organs expanded.
- Intervention effect Growth regions within organs diminished as water deficits developed.
- Observation Older tissues ceased growth completely under water deficit while younger tissues maintained some growth.
