Pineapple Biologische Bundesantalt, Bundessortenamt
and Chemische Industrie scale characteristics
Following the extended BBCH scale (Hack et al., 1992),
the entire growth cycle of pineapple is distributed into
diverse, clearly recognisable principal growth stages
ordered from 0 to 9. Each principal growth stage was
subdivided into corresponding secondary stages which
describe specific developmental events, ranging from 0
to n. The third digit of the codes was ordered from 0
to 9 and represents the percentage growth of a certain
development (1=10%, 2=20%, etc.) to acquire accurate
description.
