Other claims from this paper (19)
- Observation Untreated cotyledons had anomocytic stomata and stomata with one subsidiary cell.
- Intervention effect Growth regulator treatment yielded additional anisocytic, paracytic, cyclocytic and abnormal stomatal types.
- Intervention effect High gibberellic acid concentrations inhibited growth.
- Intervention effect Ascorbic acid increased stomatal index and guard cell size.
- Intervention effect Ascorbic acid decreased stomatal frequency.
- Intervention effect Sucrose increased stomatal index and guard cell length.
- Intervention effect Tri-iodobenzoic acid caused guard cell degeneration.
- Intervention effect At higher concentrations tri-iodobenzoic acid inhibited growth.
- Intervention effect Increasing kinetin reduced stomatal frequency, index and guard cell size.
- Intervention effect Kinetin induced contiguous stomata and guard cell division.
- Intervention effect Sulphanilamide could inhibit or promote growth depending on concentration.
- Intervention effect Coumarin at 50 p.p.m. reduced guard cell size and stomatal frequency.
- Intervention effect Coumarin at 50 p.p.m. commonly induced persistent stomatal initials.
- Intervention effect At 100 p.p.m. coumarin allowed only the radicle to emerge.
- Intervention effect At 100 p.p.m. coumarin prevented cotyledon emergence.
- Intervention effect Higher colchicine concentrations induced more persistent stomatal initials.
- Intervention effect Higher colchicine concentrations reduced stomatal frequency and index.
- Intervention effect Colchicine at 50 p.p.m. induced double pores and abnormally large pore sizes.
- Intervention effect Colchicine at 50 p.p.m. increased the size of guard cells and their nuclei.
