Between 1872 and 1891, he headed the Department of Phytology and Silviculture at the Royal Hungarian Academy of Mining and Forestry in Selmecbánya, and from 1891 until his retirement he headed the Department of Forest Management. He played an important role in the organisation of the Academy campus, the construction of new educational buildings and the development and furnishing of the botanical gardens, as well as in the compilation and development of collections related to the subjects he taught (zoology, entomology, botany, climatology and soil science). Hungarian experiments in forestry began to take institutional form in 1897/98, and Lajos Fekete was responsible for this, as well as for the idea of establishing forestry education on a secondary level. Although he had already exceeded the possible age of retirement in 1894, his tireless work ethic kept him in the Academy. He enjoyed the confidence of the Academy's teaching staff and served as vice-principal in the academic year 1892/93, then as director in the academic years 1897/98, 1898/1899 and 1899/1900, and was also head of the forestry department. At the age of 69, on 1 October 1906, he was retired at his own request, because of his failing eyesight towards the end of his life. Thus, the last serving teacher of the first faculty of the Forestry Academy left the academy chair. On this occasion, he was awarded the title of Minister Counsellor in recognition of his services. In 1910, six years before his death, he received the highest recognition for his work, being accepted as a corresponding member of the Hungarian Academy of Sciences. There is no branch of forestry science in which his work has not left a lasting mark. Despite this extremely productive and diversified career, which produced outstanding achievements in all fields, posterity has treated and still treats Lajos Fekete, whose work and human behaviour can stand as an example to us all, rather cruel.}, year = {2023}, eissn = {2061-7097}, pages = {tps://doi.org/10.29116/gerundium/2023/3-4/3} } @article{MTMT:34429467, title = {A magyar tölgy (Quercus conferta Kit.) infraspecifikus taxonjai II.

We selected a pedunculate oak population in Hungary and greyish oak population in Romania. The study randomly selected trees over 100 years old from these populations to investigate the differences between the two taxa based on leaf micromorphological characteristics. We focused mainly on indumentum because observing trichomes can be used in practice. Variation was found in trichome types, trichome-ray lengths, and stomata extent and shape. Stellate and fasciculate trichomes were absent on pedunculate oak leaves and densely developed on greyish oak leaves. The average length of the simple-uniseriate trichomes of pedunculate oak was 49.45 μm and 61.96 μm in greyish oak. On average, stomata surfaces on pedunculate oak leaves were 513.09 μm2 and 440.28 μm2 on greyish oak leaves. The study found no variation in epicuticular wax layer type. Despite the small sample size, in comparing the two populations, we found that the two taxa were distinguishable based on trichome types, and we believe that forestry practice could utilise this trait.}, keywords = {SEM; stomata; Trichome; Epicuticular wax; pedunculated oak; greyish oak}, year = {2023}, eissn = {1787-064X}, pages = {75-85} }
