Abstract
Fine structures were investigated on Pinus thunbergii needles in the coastal area of Seocheon, Korea. Both asymptomatic and necrotised needles were collected and subjected to electron microscopy and X-ray microanalysis. Particles of varying sizes and shapes covered both the asymptomatic and necrotised needles. The ratio of clogged stomata to open stomata was significantly higher in necrotised needles. X-ray microanalysis revealed particles composed of aluminium, calcium and silicon. However, sodium chloride crystals were rarely observed. These results suggest that needle necrosis in pine species may be associated with stomatal clogging by aerosol particles.
研究了韩国舒川沿海地区松柏针叶的精细结构。采集了无症状和坏死的针叶，并对其进行了电子显微镜和 X 射线显微分析。无症状和坏死的针叶上都有大小不一、形状各异的颗粒。在坏死的针叶中，堵塞气孔与开放气孔的比例明显更高。X 射线显微分析显示，颗粒由铝、钙和硅组成。不过，很少观察到氯化钠晶体。这些结果表明，松树针叶坏死可能与气溶胶颗粒堵塞气孔有关。
期刊介绍：
This peer reviewed, highly specialized journal covers forest pathological problems occurring in any part of the world. Research and review articles, short communications and book reviews are addressed to the professional, working with forest tree diseases caused by fungi, bacteria, nematodes, viruses, and phytoplasms; their biology, morphology, and pathology; disorders arising from genetic anomalies and physical or chemical factors in the environment. Articles are published in English.
Fields of interest: Forest pathology, effects of air pollution and adverse environmental conditions on trees and forest ecosystems.
