Fig. 5. — Effects of IAA on the distribution of pectins in Torenia fournieri pollen tubes. Controls (A–D, H–K, CON) and IAA-treated (E–G, L–N, IAA) tubes were labelled with JIM7 (recognizing esterified pectin) (A–G) and JIM5 (recognizing acid pectin) (H–N). (A, H) Mature pollen grains. (B, I) Control tubes cultured for 30 min. (C, J) Control tubes cultured for 1 h. (D, K) Control tubes cultured for 2 h. (E, L) IAA-treated tubes cultured for 1 h. (F, N) The forepart of an IAA-treated tube cultured for 2 h. (G) Corresponding bright field image of (F). (M) The middle part of an IAA-treated tube cultured for 2 h. The inset pictures are the corresponding bright field images. Bars = 15 μm (A, B, D, H–J, L–N), 22 μm (C, E), 67 μm (F, G), 17 μm (K).
