The secondary stages are also numbered from 0 to 9,being most related to ordinal or percentage values of growth. Hence, value 3 of principal stage 6 (flowering) is assigned when 30% of flowers open and its identification will be 613. Likewise, stage 705 identifies the value 5 of the principal stage 7 (fruit development),which represents fruit at about 50% of final size. In other cases, the values of secondary stages indicate qualitatively different stages with in a given principal phenological stage. For example, value 3 of principal stage 5 (inflorescence emergence) of secondary flowering (mes o stage 2) indicates first floral primordial just visibly and the beginning of the new (second) panicle development, and is identified as 523
