In this study, we evaluated the influence of the daily variation of both intensity of photosynthetically active radiation (PAR) and temperature on chlorophyll a fluorescence parameters in Jacarandá-da-Bahia seedlings submitted to two treatments: T1 (control) and T2 (water deficit during seven days). It was used seedling with approximately 90 days old cultivated in plastic pots contend soil. After 45 days of acclimation, the treatments were applied. In T2, the water deficit was applied by total suspension of irrigation. The physiological evaluations were made a long of the day (from 6 a.m. to 6 p.m.). The water deficit caused a significant...

We investigated the growth parameters of 20-year-old plantations of Pinus nigra J.F. Arnold and Picea abies (Linnaeus) H. Karsten and their impact on understory woody plants and we compared them with a natural stand in above-timberline mountain areas. 30 sample plots (each of 400 m2 in area) were systematically established on each site. Tree height, DBH, collar diameter, crown diameter and crown length of all trees were measured in each sample plot. The results of the diameter growth analysis of both species covered by this study showed higher numerical values in P. nigra than in P. abies. On the...

The article considers the Voronezh region climate dynamics over a 30-year period in comparison with the previous climate normal. Mathematical analysis of the relationships of cyclic changes in radial increment of native tree species of the south of the Russian Plain - Scots pine (Pinus sylvestris Linnaeus) and English oak (Quercus robur Linnaeus) ‒ with climate factors (air temperature, amount of precipitation) is done. The greatest importance of April and, especially, May sums of precipitation for the formation of radial increment of native species (P. sylvestris and Q. robur) was confirmed....

This paper presents the first comprehensive checklist of vascular plants for an especially important area for biodiversity, namely National Park "Ethnikos Drymos Oitis" - Natura 2000 site (GR2440004) and the surrounding area in Greece. This list includes a total of 1,153 plant taxa, including 79 endemic taxa and two local endemic species (Allium lagarophyllum Brullo, Pavone & Tzanoudakis and Veronica oetaea Gustavsson). It is noteworthy that 551 plants are new records for the flora of Mt. Oiti. A total of 67 taxa are protected by national and international legislation, while 52 orchid taxa are also protected by the Convention...
