• Fig. 1. Scheme of the structure of the lower (a), middle (b) and upper (c) model branches of S. euxina in the middle-aged generative ontogenetic state: red colour indicates long shoots, green – medium-length shoots, black – short shoots
  • Fig. 2. Types of metamers in the annual shoots of S. Euxina (red colour indicates proleptic generative shoot): 1 – leaf, node, short internode (the length of the internode is less than its width) and a vegetative bud of regular renewal; 2 – leaf, node, long internode (the length of the internode is much greater than its width) and a vegetative bud of regular renewal; 3 – leaf, node, long internode and sylleptic shoot, developing from a vegetative bud of regular renewal; 4 – leaf, node, long internode and generative bud of regular renewal; 5 – leaf, node, long internode (and sylleptic generative shoot with a shortened leafy lower part, developing from a generative bud of regular renewal; 6 – leaf, node, long internode and dormant bud; 7 – scale-like leaf, node, short internode and dormant bud; 8 – leaf, node, long internode and proleptic generative shoot developing from a generative bud of regular renewal
  • Fig. 3. The ratio of different types of TSS in the composition of the crown of model branches of S. euxina individuals
  • Fig. 4. The ratio of TSS types in which two-year-old shoots developfrom upper neighboring nodes (1st subgroup) or lower nodes (2nd subgroup) of three-year-old shoots of female (A) and male (B) S. euxina individuals
  • Fig. 5. The share of participation of TSSs in which two-year-old shoots develop from the upper neighboring nodes (1st subgroup) or lower nodes (2nd subgroup) of three-year-old shoots of S. euxina individuals: a – female; b – male
