Other claims from this paper (12)
- Intervention effect Moderate osmotic stress promoted pea root growth.
- Intervention effect Growth decreased at lower osmotic potential.
- Association Water potentials in mature and elongating root zones fell as sorbitol osmotic potential fell.
- Observation Turgor rose slightly in both zones at the growth promoting osmotic potential.
- Observation Turgor then declined to almost zero at the lowest medium osmotic potentials.
- Intervention effect Mitotic index rose under moderate osmotic stress.
- Intervention effect Mitotic index declined when osmotic stress increased.
- Observation Mitosis persisted after growth and turgor ceased.
- Observation At the lowest osmotic potential, prophase and anaphase frequencies declined relative to an active meristem.
- Observation At the lowest osmotic potential, metaphase and telophase frequencies rose relative to an active meristem.
- Observation Scattered metaphasic chromosomes, chromosome amalgamation and micronuclei occurred.
- Mechanism The authors suggest adverse conditions cause cells to enter Go.
