Summary The developmental stages of head cabbage ( Brassica oleracea var. capitata ) as a vegetable have been characterised by a decimal code. Five primary stages are recognised: germination, emergence and establishment, leaf formation, head formation and maturity. Each primary stage is divided into secondary stages, which apply both to single plants and to crops. Maturity is defined as the head having obtained a marketable weight and density. The standing ability is defined as the number of days from 90% of the crop being marketable to 25% of the crop having become unmarketable.
