Descriptions

Description

A pair of descriptions, ranging from 1–3 sentences that clearly indicates the trait’s scope. One description is written in plain English and for the second, technical terms are linked to published ontologies whenever possible.

Text string

dcterms:description

Linear dimension from the base to the apex of a fresh fruit, even if this is not the longest dimension.; A fruit morphology trait [TO:0002629] which is the length [PATO:0000122] of a fresh [EnvThes:21976] fruit [PO:0009001] from the fruit proximal end [PO:0008002] (base) to the fruit distal end [PO:0008001] (apex).

Comments

Additional notes about the scope of the trait or acceptable methods.

Metadata required for processing

Type

Type of trait, specifying if traits are categorical, numeric, or ordinal

Entity IRI**
