The annual growth cycle of a grapevine (from one winter to the winter of the following year) is characterised by the fol lowing specific main categories of growth and developmen tal stages (phenology), namely: (i) dormancy, (ii) bud break, (iii) shoot, leaf and flower cluster development, (iv) flowering, (v) berry development, (vi) berry ripening until ready for harvesting, (vii) leaf ageing with the onset of autumn colours and (viii) complete shoot lignification followed by leaf drop. Each of the above-mentioned main phenological stages is characterised by several albeit specific development pat terns, the detail of which is best revealed under the prover bial magnifying glass. The objective with the compilation of this photo series was to portray comprehensively the par ticulars involved in the entire spectrum of the annual grape vine growth cycle over several months in Wynboer . The photos are not intended to reflect a single grapevine or even cultivar, although, where applicable, the cultivar name is mentioned.
