Data dictionary: Dormancy evaluations
Characteristic | Abbreviation | Description | Units |
---|---|---|---|
Number of Sample | SAMPLE | number | |
Initial tuber weight | ITW | The same day or a day before tuber storing | gr. |
Date of sprouting | DATESP | date | |
Dormancy period | DORPD | Counted as days from haulm_cutting to sprouting of 80% of the tubers with at least one sprout longer than 2 mm. Monitoring of sprout initiation and growth should be carried out at 10 day-intervals in order to record an accurate dormancy period | days |
Number of Sprouts | NSP | 45 days after recording dormancy period (at storage temperature >15°C) and 60 days after recording dormancy period under cold storage (2-4°C). The date for recording this variable will differ among clones as it depends on the date dormancy period of a clone was recorded | count |
Length of the longest | LGLNSP | 45 days after recording dormancy period (at storage temperature >15°C) and 60 days after recording dormancy period under cold storage (2-4°C). The date for recording this variable will differ among clones as it depends on the date dormancy period of a clone was recorded | mm. |
Length of the lateral sprout number | LGLATSP | 45 days after recording dormancy period (at storage temperature >15°C) and 60 days after recording dormancy period under cold storage (2-4°C). The date for recording this variable will differ among clones as it depends on the date dormancy period of a clone was recorded. Measure should be performed in every lateral sprout of a tuber (exclude the longest one). An average is calculated per tuber | gr. |
Average length of lateral sprout | AVLGLATSP | mm. | |
Thickness of apical sprout | THASP | mm. | |
Thickness of lateral sprout number | THLSP | number | |
Average sprout thickness | AVTHSP | 45 days after recording dormancy period (at storage temperature >15°C) and 60 days after recording dormancy period under cold storage (2-4°C). The date for recording this variable will differ among clones as it depends on the date dormancy period of a clone was recorded. Measure should be performed in at most three sprouts per tuber in multiple sprouting tubers(include the longest one) Suggestion: use a Vernier calliper. An average is calculated per tuber | number |
Final tuber weight | FTW | 45 days after recording dormancy period (at storage temperature >15°C) and 60 days after recording dormancy period under cold storage (2-4°C). The date for recording this variable will differ among clones as it depends on the date dormancy period of a clone was recorded. Remember to remove sprouts carefully before weighing | number |
Percentage weight loss of unsprouted tuber | PW_USPT | % | |
Percentage weight loss of sprouted tuber | PW_SPT | % | |
Sprouting pattern | SPPAT | Apical sprout or an average less than 2 sprouts per tuber, an average of less than 3 be considered a partial dominance, or more sprouts per tuber indicates the absence of apical dominance or a pattern of multiple sprouts | text |
