Biometric characteristics of the assimilation apparatus of self-seeding pine in the post-fiery area

Reforestation in post-fire areas is becoming increasingly important in a situation where the number and area of forest fires in the country as a whole do not decrease. The data on the restoration of the rocky pine forest on the burned area 14 years ago are presented. It has been established that the young generation of pine in the post-fire area differs both in height and age. The aim of the research was to determine the variability of the biometric characteristics of needles depending on the height of the undergrowth and the amount of growth in height. The range of variation in the length and weight of the needles depends on the growing conditions. The needles of pine undergrowth in the illuminated areas of the post-fire areas, as a rule, have a shorter length and a greater weight compared to the needles of plants growing in the shade. The length of the needles formed in 2020, depending on the height of the model trees, is from 20 to 36 mm, and the weight of 100 pairs of needles is from 0.30 to 0.98 g. The specific gravity of the needles is a more objective characteristic of the assimilation apparatus than the mass or length of the needles.
