Fig. 4. Transmission electron micrographs of cuticle thickness of abaxial leaf surfaces in selected two-year-old ginseng lines resistant to high-temperature injury (HTI; Yunpoong, high-temperature injury resistance [HTIR] 1, HTIR 2, and HTIR 3) and susceptible to HTI (Chunpoong). Arrow indicates vesicle. Bar in HTI resistant lines=2 nm; HTI-susceptible line=500 nm. C, cuticle; CW, cell wall.
