Fig. 3. — Polysaccharides in Abies koreana and Picea jezoensis cone tissues through development. (A) Massive starch accumulation (arrows) within the cells of bract scales in the spring buds of A. koreana. (B) Starch (arrows) depletes concomitantly with cell elongation in the bract scales of A. koreana during bud break. (C) Starch (arrows) accumulates in the bract scale primordia of the pre-winter buds of P. jezoensis. (D) In contrast, starch is depleted from cells of the bract scales within the spring buds of P. jezoensis. (E) Starch (arrows) accumulates around the ovules of A. koreana at the pollination stage, when the seed cones open. (F) Similarly, starch accumulates around the ovules of P. jezoensis at the pollination stage. Scale bars (A–D) = 20 µm; (E, F) = 100 µm.
