Needle Damage Development in Norway Spruce Seedlings as Affected by Humidity, Temperature, and Gray Mold: A Preliminary Study
Figure 2
(a) The percentage of damaged needles on the inoculated and control seedlings as mean of tray means. In the seedling sets 1 and 2, the first two group bars denote 3-month-old seedlings and the second two group bars 6-month-old seedlings. In seedling set 3, the seedlings were 5.3 and 5.8 months old. (b) The percentage of damaged needles on inoculated seedlings 1–11 days after inoculation.
