Other claims from this paper (15)
- Observation Rice leaf elongation was 15 to 30% greater by day than night under both water regimes.
- Observation Night temperatures below 27 C limited rice leaf elongation at night.
- Observation At night temperatures above 27 C, rice night elongation exceeded day elongation.
- Observation Bulk leaf turgor was lower by day than night, opposite the elongation pattern.
- Observation Leaf elongation declined after illumination and remained low for 15 to 60 minutes.
- Observation After the initial illumination inhibition, rapid elongation resumed.
- Observation Elongation then declined to steady night rates within 30 to 60 minutes.
- Intervention effect Removal or covering of subtending leaves eliminated light transition perturbations.
- Intervention effect Irrigation during light induced inhibition did not change elongation in well watered plants.
- Intervention effect In stressed plants, irrigation immediately restored high elongation rates.
- Intervention effect Root hydrostatic pressure accelerated elongation of intact plants.
- Observation Elongation increased with pressure to approximately 5 bars.
- Observation Elongation did not increase further above approximately 5 bars.
- Intervention effect Adding osmoticum to root medium altered the pressure response.
- Observation Leaf elongation occurred only when the water potential gradient allowed absorption.
