Other claims from this paper (12)
- Observation Irradiated Golden Delicious lateral buds grew into budless spurs and swollen tips the next year.
- Observation Irradiated lateral bud apices had thick-walled, lightly stained cells in mid-June.
- Observation Outer tunica was more radiation resistant than inner layers and corpus; pith rib meristem was more resistant still.
- Observation Inflorescence and floral meristems were rare but developed after forming.
- Observation One-year budless spurs lacked an organized apical meristem and leaf primordia.
- Observation Budless spur apices often had folded surfaces.
- Observation Periderm and subsequently deep wound cambium developed.
- Mechanism Expansion of several tissues enlarged club tips and swollen spurs.
- Observation Many lateral buds removed from irradiation in August produced long shoots with terminal buds.
- Observation Delicious, Golden Delicious and McIntosh were more radiation sensitive than Cox, Macoun and Spy.
- Observation Acute and chronic irradiation produced similar first-year bud symptoms.
- Association Apical meristem death varied with developmental stage, meristem structure and genotype.
