Other claims from this paper (16)
- Intervention effect Deferring planting may considerably reduce susceptibility of potato tubers to dry rot.
- Intervention effect Removing the haulm prematurely may considerably reduce susceptibility of potato tubers to dry rot.
- Intervention effect The treatments reduced dry-matter content of potato tubers.
- Association No direct relationship between dry-matter content and susceptibility of potato tubers was established.
- Observation High pre-maturity susceptibility of potato tubers was confirmed at flowering.
- Association Susceptibility of potato tubers decreased as the haulm matured.
- Observation When the haulm was dead, potato tubers were resistant to dry rot.
- Intervention effect Within a fortnight after premature haulm removal, potato tubers became completely resistant.
- Intervention effect Premature haulm removal decreased sucrose content of potato tubers.
- Intervention effect Premature haulm removal did not change the content of reducing sugars in potato tubers.
- Mechanism Susceptibility of the immature potato tuber is suggested to be closely related to sucrose content, which accumulates from rapid translocation from the growing haulm.
- Association Tuber susceptibility to dry rot increased slowly during storage.
- Association Reducing sugars increased in potato tubers during storage.
- Association Tuber susceptibility and reducing sugars were not directly related during storage.
- Intervention effect Application of 6 cwt/acre of 12:12:18 NPK fertilizer to Catriona significantly reduced liability to infection compared with a non-fertilized plot.
- Intervention effect Sulphate of ammonia alone significantly increased tuber susceptibility compared with complete fertilizer.
