Rhododendron honey is a monofloral honey and it is collected from the flowers of Rhododendron species widely spreading over many countries, mainly in America, Turkey, Indonesia, Australia. It is belived that Rhododendron honey treats several disorders and is used traditionally as an alternative medicine. The determination of the chemical characteristics of the Rhododendron honey is essential for public health. In this research, the physicochemical characteristics of Rhododendron, chestnut and flower honey samples collected from beekeepers in Turkey were determined and compared. Physico-chemical parameters such as moisture, acidity, sucrose, invert sugar, fructose/glucose, conductivity, diastase and hydroxymethylfurfural were analysed in each honey sample. According to the results obtained, no differences were found in physico-chemical properties of Rhododendron, honey samples, except from moisture and acidity compared with those of chestnut and flower honeys. In order to differentiate Rhododendron honeys, new methods should be developed. This honey should be reintroduced to medicine and used in pharmaceutical industry.

A search for endophytes in Castanea sativa Miller (Fagales: Fagaceae) grafting scions showed that a latent pathogenic fungus Gnomoniopsis smithogilvyi (Diaporthales: Gnomoniaceae) was present as the major component of the endophytic flora. Initially, the goal of this study was to develop a biological control method of Cryphonectria parasitica (Diaporthales: Valsaceae), the chestnut blight agent, by soaking chestnut scions before grafting in antagonists suspension. However, the healthy chestnut material used in in vitro and glasshouse experiments turned out to be naturally infected by a pathogen. At first view, the symptoms looked very similar to those caused by C. parasitica but some differences were noticed. DNA sequencing and application of Koch’s postulates revealed that G. smithogilvyi was the agent responsible of those symptoms. Preventive biocontrol experiments were carried out with chestnut tree scions soaked overnight in a liquid suspension of Bacillus amyloliquefaciens (Bacillales: Bacillaceae). This bacterium was then frequently found in the lower parts of scions (CF of 100% between 3.1 and 6 cm) and up to a height of 18 cm. It was observed that when B. amyloliquefaciens was present, the endophytic and opportunistic pathogenic fungus G. smithogilvyi was not present. Conversely, the parts not colonized by the bacteria were always naturally infected by the endophytic fungus. This would indicate that the endophytic behavior of B. amyloliquefaciens inhibited the growth of G. smithogilvyi and reduced its presence in scions. A similar experiment, carried out with the Trichoderma atroviride (Hypocreales: Hypocreaceae), led to similar observations. Trichoderma atroviride was frequently isolated in the lower parts of scions (CF of 100% until 6 cm) and up to a height of 27 cm. Inoculating B. amyloliquefaciens and T. atroviride as part of a preventive biocontrol treatment would allow these biological control agents to colonize the plant as endophytes and prevent the development of G. smithogilvyi.

European chestnut (Castanea sativa Mill.) is one of the most known trees occurring in Europe. Therefore history of spread of the species on this continent is a subject of interest of many authors. At present this species is naturalized in southern and middle Europe. In Poland it is often cultivated in parks, gardens but it has not been treated as a permanent element of the Polish flora so far. The closest localities, where it is naturalized, are in Czech and middle Germany. In the years 2000–2005 spontaneous spread of the species on the Baltic coast in urban sites (town of Łeba, 54°45’N, 17° 33’E) was observed, where its population amounts to one hundred of individuals dispersed up to 600 m. This is the first locality of Castanea sativa in Poland, where it occurs spontaneously. This finding would probably enable to move the border of European chestnut range in Europe towards northern-eastern direction by several hundreds kilometers.

The influence of distance between host trees and leaf litter removal on population density of Cameraria ohridella have been for the first time examined in an isolated population of horse chestnut (Aesculus hippocastanum L.) trees. The observation was performed in the small town (area 13,58 km²) in Wielkopolska region (West Poland) on the total number of 49 trees: 31 (11 clumps) of them with autumnal leaves removal (controlled sites), and 18 (5 clumps) without this procedure (uncontrolled sites). The main factors determining the extent of the leaf destruction by larvae were the leaf litter removal and the number of subsequent generations on a given tree. The effect of mean distance between trees on the infestation level was statistically significant only for the third generation larvae, when analyzing all sites. There was no significant correlation when checking the impact of mean and short distance on the leaves infestation between controlled and uncontrolled sites. The abundance of the first generation of the larvae of raked sites is possibly a result of low number of in situ overwintering individuals and the number of immigrants from uncontrolled areas. Assuming the random choice of direction of the migration, the effect of the immigrants on the trees which leaves have been disposed of is not as high as it should be expected. Additionally, the moths can be blown away by the wind in a random direction. Consequently, the noted increase in the leaves infestation by the third generation larvae can be result of the rate of population increase innate for the species and only partly a result of immigration from refuge areas.

In order to enhance the contribution of fig to the national economy and to raise farmers’ income level, it is necessary to encourage further cultivation of fig and direct farmers to fig production instead of alternative products. Most of the areas suitable for chestnut production are forestlands. There are orchards arranged with oak and chestnut trees with oak being predominant. Chestnut population in these areas should be increased. Cultivation area of this product that has many fields of use needs to be extended. Directing farmers to products that are storable in medium term with a broad market and high income is important both for the national economy and the farmers. The purpose of the present study is to remind producers the significance of two important products: fig and chestnut in the Kosk district of the Aydin province, Turkey, and to determine the areas suitable for growing these products within the study area. For this purpose the questioning and analysis features of GIS was employed. In this study, rainfall, temperature, soil texture, slope, elevation, wind direction, were taken into account to identify appropriate fields. As a result, approximately area of 13886 hectare of fig production and 3430.7 hectare of chestnut production were found as suitable area.
