FULL FLOWERING (FULL BLOOM) International phase code BBCH 65 (Growing stage.., 2001; Meier et a l, 2009) Phase description The phase is considered to have begun when 50% or more of plant specimens in the transect are flowering. Further info Fenolog. rgo.ru: Flowering is at peak (full bloom) when most of the flowers on trees are open. Drying up of corollas in a majority of flowers is considered to indicate the end of the flowering phase. Terentjeva E. Yu. (2008): Full flowering - flowers are more abundant than flower buds; there are first wilted flowers, while flower buds are still present. Sinel'nikova N. V. and Pakhomov M. N. (2015): Full flowering is ob served when more than 50% of specimens are blooming. This means inflorescences are in full bloom, and the corollas of most flowers are open. In wind-pollinated plants, anthers fully open and pistils of female flowers emerge. 7. FLOWER WILTING ONSET International phase code BBCH 66-67 (Growing stage.., 2001; Meier et al., 2009) Phase description A species is considered to have entered this phase when 10% of spec imens in the transect have withered flowers on them. Some corollas in inflorescences have already wilted, drooped or shriveled, whereas others only begin to open (rosebay willowherb) or long remain open and continue flowering (yarrow). In wind-pollinated plants, pollen has been fully shed from 10% of specimens. In some cases this phase is difficult to record, and accuracy requires that the transect is visited more often and specimens of some species are inspected with more scrutiny (dwarf cornel, yarrow, birch).
