Needle Damage Development in Norway Spruce Seedlings as Affected by Humidity, Temperature, and Gray Mold: A Preliminary Study

Table 2

Univariate analysis results for the effects of treatment, age, and inoculation on the percentage of damaged needles per seedling (a) in seedling set 1, treatments 25/80 and 25/50 to 3- and 6-month-old seedlings. (b) In seedling set 2, treatments 15/80 and 15/50 to 3- and 6-month-old seedlings. (c) In seedling set 3, treatments 25/50, 15/50, 25/80, and 15/80 to 5.3- and 5.8-month-old seedlings.
