Rootstock Vigour Classification Lookup

Classify actual matched rootstock trial/reference shoot dry mass ratios under caller bands; not universal vigor labels from names, cane mass/length or canopy width, scion/site confounds external.

Description

Rootstock vigor comparisons depend on matched scion, site and trial conditions.

Rootstock vigor comparisons depend on matched scion, site and trial conditions. Relative shoot dry mass can be grouped using explicit local bands.^[1]

Enter nonempty aligned unique trial IDs, nonnegative trial/positive reference masses, positive strictly increasing edges and one more unique class label than edges. Return ratios and caller labels.

When to use Rootstock Vigour Classification Lookup

Use Rootstock Vigour Classification Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. No rootstock database, universal vigor class or correction for trial confounding is supplied.

Prepare the measured vineyard records, aligned lists and independently verified local limits or catalog requested. Keep units, crop stages and observation periods consistent.

How to use Rootstock Vigour Classification Lookup and understand its results

Prepare the measured vineyard records, aligned lists and independently verified local limits or catalog requested. Keep units, crop stages and observation periods consistent.
Enter callerRootstockTrialIds, matchedTrialShootDryMassGrams, matchedReferenceShootDryMassGrams, callerVigourRatioUpperEdges, callerVigourClassLabels using the field table and calculation rules, then run the tool.
Read matchedTrialRelativeDryMassRatios, callerTrialVigourClassLabels. 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
callerRootstockTrialIds	Caller rootstock trial ids	list of string	Required
matchedTrialShootDryMassGrams	Matched trial shoot dry mass grams	list of number	Required
matchedReferenceShootDryMassGrams	Matched reference shoot dry mass grams	list of number	Required
callerVigourRatioUpperEdges	Caller vigour ratio upper edges	list of number	Required
callerVigourClassLabels	Caller vigour class labels	list of string	Required

Enter nonempty aligned unique trial IDs, nonnegative trial/positive reference masses, positive strictly increasing edges and one more unique class label than edges. Return ratios and caller labels.

ratio=trialMass/referenceMass; class=first inclusive upper edge, otherwise final class

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
matchedTrialRelativeDryMassRatios	Matched trial relative dry mass ratios	list of number
callerTrialVigourClassLabels	Caller trial vigour class labels	list of string

Limitations and assumptions

No rootstock database, universal vigor class or correction for trial confounding is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Bud Fruitfulness Cluster Per Shoot Lookup: Bud fruitfulness distinguishes clusters per burst shoot from burst shoots per retained bud. Those denominators should stay separate. For a complementary task, use Bird Damage Loss Percent Estimate Calculator: Protected-versus-exposed harvest comparisons give an apparent loss proxy. Protection can change conditions beyond bird access.
