Text Appearing Before Image:
8 CIRCULAR 516. U. S. DEPT. OF AGRICULTURE spread out in a shallow layer in this tray without packing the foliage, and this will prevent the uneven penetration of the heat during treat- ment. As shown in figure 5 c, a temperature of 110° F. was reached
Text Appearing After Image:
Figure 6.—Normal gerbera leaf (A) compared with one from plant injured by treatment in hot water (B). The treated leaf shows necrotic brown areas on each side of the midvein. between 2 and 3 minutes after beginning treatment, among both crowns and leaves; and the temperature decreased more rapidly after treat- ment than it did in the treatments in crates (fig. 5, a and b).
