Mesophyll cell fine structure of needles from pine trees growing around the Skrunda Radio Location Station, Latvia



Mesophyll cell fine structure of needles from pine trees growing around the Skrunda Radio Location Station, Latvia



Proceedings of the Latvian Academy of Sciences Section B Natural Exact & Applied Sciences 51(5-6): 265-269



Needles from pine trees (Pinus sylvestris L.) near the Skrunda Radio Location Station, western Latvia, were collected for light and electron microscopic investigations and compared with those of trees not directly irradiated by electromagnetic radiation. Discoloration and necrotic spots at the needle tips developed as visible symptoms of exposed trees and the needle lengths were significantly reduced. According to previous studies dealing with effects of air pollution, the mesophyll cells are well suited for the detection of initial cytological injuries. Therefore, mesophyll tissue from green mid-segments of the needles was examined. However, comparisons between needles from exposed and unexposed pine trees did not reveal alterations in the mesophyll fine structure. Within the mesophyll cells, the thylakoidal system of the chloroplasts was well developed and the stroma appeared without symptoms. Reduced needle lengths may indicate a possible influence of electromagnetic radiation on processes during needle formation rather than on the fine structure of mature needles.
