SoyBase Soybean Growth Stages Conversion Page


The Soybase Soybean Whole Plant Growth stage ontology (SOY growth) was developed to unite the familar soybean growth and development stages (V and R stages) with the more generic Plant Ontology Whole Plant Growth stages (PO) and the BBCH scale. This is intended to facilitate the translation of observations using these disparate ontologies and allow researchers to more easily collate the relevent literature based on shared developmental points.
