SEASONAL CYCLES IN PLANTS A seasonal development cycle in plants is made up of successive, morphologically discrete stages or periods. Each stage comprises several seasonal (phenological) development phases (Solovyov, 2005a; Terent- jeva, 2008; Sinel’nikova and Pakhomov, 2015). As a rule, six such stages are distinguished, three of them associated with the development of vegetative organs (1,5, 6), and the other three - of generative organs in plants (2, 3, 4, Tab. 2): 200 ......................................................................................................A phenological atlas of plants Table 2 Principal phenological stages and phases of plants Phase NN S I re ф * </> according to A.
