Other claims from this paper (10)
- Observation The af and tl mutations did not affect the length and number of internodes in pea.
- Observation In all pea plants the ABA level in leaves was 3-10 times greater than in roots.
- Observation The ABA level rose in both leaves and roots in the course of vegetative growth.
- Observation The increase in shoot area of the tl mutant did not change the dry weight of underground and above-ground parts.
- Observation The shoot/root ratio in the tl mutant was identical to that in wild-type pea plants.
- Mechanism Maintenance of shoot dry weight in the tl mutant at the wild-type level despite larger leaf area was accounted for by a decrease in thickness of leaflet and stipule blades.
- Observation The ABA level in the stipules of mutant plants was greater than in wild-type plants.
- Observation The ABA level in the roots of the af mutant was twice that in the leafy forms.
- Mechanism ABA was assumed to participate in the control over root growth exerted by the shoot.
- Observation The ABA level in the stipules of af plants was three times higher than in wild-type plants.
