The extended BBCH-scale is a system for a uniform coding of phenologically similar growth stages of all mono- and dicotyledonous plant species. It results from. characterize specific growth stages using the BBCH scale. In Manitoba some crops cover a larger area in terms of acreage, and so may be more commonly. 31 Mar In this article, a proposed scale of the phenological growth stages of quinoa based on the BBCH coding system (Biologische Bundesanstalt.

Scheme of the annual cycle and the principal growth stages of saffron Crocus sativus L. Nevertheless, there are currently no universally used keys to describe the entire development cycle of this plant. Hypocotyl with cotyledons breaking through seed coat. Figure 2 shows that some stages overlap or run concurrently in the saffron plant cycle for instance, leaf appearance and flowering, among others ; thus, it is recommended that both stages should be noted separating their codes by a forward slash.
