BBCH-scale (cucurbit)



The BBCH-scale (cucurbit) identifies the phenological development stages of cucurbits (Cucumber = Cucumis sativus, melon = Cucumis melo, pumpkin, marrow, squash = Cucurbita pepo, calabash = Cucurbita pepo var. giromontiina, water-melon = Citrullus var. vulgaris). It is a plant species specific version of the BBCH-scale.

A downloadable version [1] of the BBCH Scales, including illustrations, is available from the BBA [2] (Federal Biological Research Centre for Agriculture and Forestry)
