Cane Weight Selection Threshold Checker
Compare measured dry cane mass per actual length against caller selection calibration; raw cane weight alone is length-confounded and this band does not establish viable/suitable fruiting wood.
Description
Cane mass depends on its length.
Cane mass depends on its length. Dry mass per unit length permits comparisons without treating longer canes as automatically more vigorous.
Compare measured dry cane mass per actual length against caller selection calibration; raw cane weight alone is length-confounded and this band does not establish viable/suitable fruiting wood.
When to use Cane Weight Selection Threshold Checker
Use this tool to compare measured dry cane mass per actual length against caller selection calibration; raw cane weight alone is length-confounded and this band does not establish viable/suitable fruiting wood.
Prepare vineyard measurements, dates or block records for the intended growing period. Keep weights, counts and weather observations in the stated units.
How to use Cane Weight Selection Threshold Checker and understand its results
- Prepare vineyard measurements, dates or block records for the intended growing period. Keep weights, counts and weather observations in the stated units.
- Enter measuredCaneDryMassesGrams, measuredCaneLengthsCm, callerMinimumMassPerLengthGramsPerCm, callerMaximumMassPerLengthGramsPerCm using the field table and calculation rules, then run the tool.
- Read observedCaneMassPerLengthGramsPerCm, withinCallerSelectionBandFlags. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| measuredCaneDryMassesGrams | Measured cane dry masses grams | list of number | Required |
| measuredCaneLengthsCm | Measured cane lengths cm | list of number | Required |
| callerMinimumMassPerLengthGramsPerCm | Caller minimum mass per length grams per cm | number | Required |
| callerMaximumMassPerLengthGramsPerCm | Caller maximum mass per length grams per cm | number | Required |
Align nonnegative dry masses with positive lengths and ordered nonnegative selection bounds. Return ratios and flags within both inclusive endpoints.1
Paired lists must be nonempty and have equal lengths.
mass per length = dry grams/length centimeters Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedCaneMassPerLengthGramsPerCm | Observed cane mass per length grams per cm | list of number |
| withinCallerSelectionBandFlags | Within caller selection band flags | list of number |

}Limitations and assumptions
The band does not establish viable or suitable fruiting wood.
Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Pruning Weight Per Vine: Pool actual pruning inventories by sampled vine counts while explicitly separating fresh/dry bases; not simple unweighted sample means, wood nutrient content or vine vigor diagnosis. For a complementary task, use Internode Length Vigour Indicator: Audit measured adjacent node distances and fraction above caller internode threshold, not a fixed cultivar vigor score or original nodes inferred from cane length.
