Abstract

A detailed phenological scale for maize was developed for use under W. European conditions. Primary and secondary growth stages were distinguished and characterized with a decimal code. Growth stages were easily recognizable in the field. Development codes were related to an ontogenetic time expressed in accumulated temp. by using detailed phenological observations from 2 field experiments. An approx. linear relationship was found between accumulated temp. and development codes with a discontinuity around anthesis. (Abstract retrieved from CAB Abstracts by CABI’s permission)
