Ap. Everaarts, A DECIMAL CODE DESCRIBING THE DEVELOPMENTAL STAGES OF HEAD CABBAGE (BRASSICA-OLERACEA VAR CAPITATA), Annals of Applied Biology, 125(1), 1994, pp. 207-214
The developmental stages of head cabbage (Brassica oleracea var. capit
ata) as a vegetable have been characterised by a decimal code. Five pr
imary stages are recognised: germination, emergence and establishment,
leaf formation, head formation and maturity. Each primary stage is di
vided into secondary stages, which apply both to single plants and to
crops. Maturity is defined as the head having obtained a marketable we
ight and density. The standing ability is defined as the number of day
s from 90% of the crop being marketable to 25% of the crop having beco
me unmarketable.
