“…They might be attributed to the species' low resistance to summer water stress, especially in a summer as extreme as that of 2013, as well as to the generally poor quality of its seedlings and the fact that they came from natural regeneration and may have undergone some shock when transferred from a shaded environment to full sun. This is in line with findings of Tabari et al (2005) who found that Fagus orientalis seedlings from natural regeneration that grew under the canopy until transplanting had growth difficulties under direct light that manifested in decreased shoot growth with increasing gap size. Johnson et al (1997) stated that the growth of container bred F. sylvatica seedlings was better in small gaps than in the understory or clearings.…”

Abstract:The conversion of old black pine plantations into ecologically more stable broadleaf forests is an important goal in many Mediterranean countries. Six experimental plots split between more and less productive sites were established in the sub-Mediterranean climate zone of south-western Slovenia in an area of mostly pure black pine stands. In November 2012 they were planted with six native broadleaf species (Celtis australis, Quercus petraea, Fagus sylvatica, Prunus avium, Juglans regia and Acer pseudoplatanus). The test plantations were intended to become small initial nuclei from which the introduced broadleaf species could later spread naturally into the old and partly degraded pine plantations. Seedling condition was assessed one year after planting. Based on their high survival rates after the first growing season, all tested species except F. sylvatica showed promising potential for future conversion of old pine stands in the Slovenian Karst region. However, the results of one growing season only are insufficient to draw firm conclusions. Of all planted species P. avium had the highest survival rate (95%) and was least susceptible to poor field conditions. Without exception, all species showed lower survival rate on the less productive site. Unlike other species, P. avium and J. regia seedlings had considerable height increment, while F. sylvatica had the lowest. From the results we can assume that perhaps old pine stands in the area have already considerably improved soil conditions and thereby enabled the introduction of broadleaves.Additional key words: planting broadleaves, forest conversion, survival rate, height increment, tree vigour

“…6). Tabari et al (2005) reported that most seedlings of Fagus orientalis were not discoloured or they were slightly discoloured under gaps of 50, 200 and 600 m 2 and slightly to moderately discoloured in the open. There was a general tendency of higher discoloration in larger openings.…”

Beech (Fagus orientalis Lipsky) is the most industrial commercial tree species among more than 80 broadleaved trees and shrubs in Hyrcanian forests. In this study some of the silvicultural properties of beech were studied under a shelterwood cutting system in a regeneration unit of 25 years old stand in Sangdeh forests of Iran. Tree height, diameter, canopy cover, variety of species, frequency at different stages of growth (seedling, sapling, thicket and pole) and tree density at juvenile phase were recorded in 431 circular 1,000 m 2 sample plots before and after shelterwood cutting. Results indicated that tree density in the diameter at breast height (dbh) class of < 20 cm increased during shelterwood cutting. Canopy cover of regeneration unit was 78.5% in 1957, while in 2000 and after the shelterwood cutting it reached 59%. Growing stages of regeneration were 14% sapling, 21% thicket, 24% small pole and 41% pole. The shelterwood method has not been very successful in our study area due to a number of technical and potential problems.

“…Thus, our results indicate no significant difference in seedling germination in response to gap size; however, establishment of F. orientalis appears to vary by gap size. In a gap-planting experiment in northern Iran (Tabari et al, 2005), small gaps (50 m 2 ) had higher survival rates for planted seedlings compared to larger gaps (600 m 2 ). Thus, Sagheb-Talebi and Schutz (2002) recommend using group selection cuts where 2-4 overstory trees are removed to produce the next generation of F. orientalis trees.…”
