Other claims from this paper (19)
- Observation Mottled seeds reached 97% germination under alternating 20 and 30 degree temperature cycles in 12 days.
- Observation Grey seeds reached 80% germination under alternating temperature cycles in 12 days.
- Observation Purple seeds reached 21% germination under alternating temperature cycles in 12 days.
- Intervention effect Two alternating temperature cycles gave mottled seeds germination close to that of ten additional cycles.
- Intervention effect Two cyclic temperature changes gave grey and purple seeds one-fourth of the maximum germination obtained with ten additional cycles.
- Intervention effect Hot water extracts of seeds inhibited seedling growth.
- Intervention effect Hot water extracts from more mature seeds inhibited seedling growth less than extracts from less mature seeds.
- Intervention effect Alternating temperature with 20 mg per liter adenine sulfate gave maximum growth of isolated root tips.
- Intervention effect Kinetin at 10-4 mg per liter and above was a potent inhibitor of seedling and isolated root tip growth.
- Intervention effect IAA at 1 mg per liter induced maximum lateral root initiation on root segments.
- Intervention effect IAA at 1 mg per liter allowed no buds to form.
- Intervention effect IAA only induced callus on root segments grown on media supplemented with adenine sulfate.
- Intervention effect Bud formation was negligible in both kinetin-treated and untreated segments.
- Intervention effect Callus formation on basipetal segment ends was diminished as the included kinetin concentration increased.
- Intervention effect Kinetin at 10-2 mg per liter gave maximum stimulation of bud formation on hypocotyl segments.
- Intervention effect IAA at 10-4 mg per liter removed the kinetin-induced bud formation effect.
- Observation About 90% of the aboveground shoots of established leafy spurge patches arose from adventitious buds on lateral roots.
- Observation Buds arose endogenously in roots but exogenously in the hypocotyl region.
- Observation The exarch-to-endarch stele transition in the collet was complete in about 2500 microns.
