Fig. 3 from Sutinen et al. (2009): (A) Longitudinal section of a vegetative spruce bud sampled in the field on 17 January 2007. The primordial shoot is about one-third of the total length of the bud. The line on the bud shows the measuring point of the primordial shoot and that of the whole bud. The bud scales (Bs) are compact and glossy at the outer surface, but delicate and white around the primordial shoot. Bar = 1 mm. (B) Upper surface of primordial shoot from A. Primordial needles are tightly pressed against the primordial shoot and their tips are all blunt (C) giving a rounded appearance to the tips when viewed around the naked, star-shaped apex at the top of the bud. Bars in B = 0.5 mm and in C = 0.2 mm. This figure appears in colour in the online version of Tree Physiology.
