   Author: Dr. Fevzi BILGIN  , Dr. Salih PARLAK, Emin KAYMAKCI

ABSTRACT

This study has been carried out to produce some information about bay laurel (Laurus nobilis L.) plantations and also aimed to examine first harvesting period of laurel leaves during 1997-2006 periods.
It is established for summer harvesting according to randomized blocks at Urla-İzmir province in Ege Region of Turkiye with (1+0) saplings of nine half siblings from Kuşadası origin in Aydın. In the same area, another trial has been established according to single tree plots to determine the effect of winter harvesting on leaf weight and leaf oil yields.
According to first harvesting period study results, it is proposed for the plantations to be established for leaf production, first leaf harvesting might be advised at fifth year of plantation and rotated once every two years in place of once every three years. Winter harvesting could be preferred for leaf harvest because of much more than summer leaf yields if not drying problems and/or high production costs.

Authors: Dr. Saide Nafisi BALAY, Dr. Peyman CAN, Dr. Meltem ÖZÇANKAYA, Cemhan BUCAK

ABSTRACT

This project was constituted between 2003-2007 in three research sites each established in Balıkesir, İzmir and Muğla to determine the diseases and pests of Laurus nobilis (L.), one of the Turkey’s important non woody exported products. In all research sites, the pests on leaves, shoots, branches and barks have been defined. In addition, hole traps were used. As the result, Cacoecimorpha pronubana (Hübner), Archips rosanus (Linnaeus) (Lep., Tortricidae), Otiorhynchus ovalipennis Boheman in Scönherr (Col., Curculionidae),  Trioza alacris Flor. (Hom., Triozidae) and some species related to Orthoptera were determined as pests of L. nobilis. Among these pests, T. alacris was the most widespread, with the most damage. In addition, since it has some to four generations annualy, C. pronubana is advised to be pursued, especially in Bandırma. Laurel diseases and their sources were investigated in leaves, current-year twigs and branches. Fungi isolated from the apical parts of shoots showing fresh necroses and leaf spots were identified and the pathogenicity of some of them was determined. Some species were isolated at all four sites; the most consistent members of this group were Phomopsis sp. B, Botryosphaeria sarmentorum, Phomopsis sp. C and Phoma sp.. Other less frequently recovered species were Seimatosporium lichenicola, Colletotrichum gloeosporioides, Hendersonula sp., Phomopsis sp. A, Paraconiothyrium sp. and Colletotrichum dematium. The isolation frequencies of the dominant species, as well as other less frequent species, were significantly dependent on the sampling site. The degree of pathogenic infection and the diversity of fungal species were significantly higher in the spring.

Authors:Dr. Salih PARLAK

ABSTRACT:

The project named “Seedling Propagation in Container of Bay Laurel (Laurus nobilis L.) and Planting Success in Field (Seferihisar Case)” was studied between 2003-2007. Plantation phase was done at Torbalı Forestry Nursery and the field trials in Seferihisar-Doganbey afforestation field. The studies on bay laurel nursery techniques are merely rare and it was established that the vitality percentages of saplings used in afforestation fields in previous years were considerably low. Research results showed that this failure can be caused by the sapling’s origin, container and the media types. The sapling characteristics effects on vitality percentage augment in laurel used in afforestation fields are unknown. In this study, the factors affecting these characteristics are choosen such as container type, media mixture and origin. In origin selection, the criterion was the plants with the highest leaf quantity and quality. So the seeds were collected from the regions having this property. Ignoring the volume and shape of the container as a factor, 3 different container types were determined, and the media used were the mixture of media materials in 3 different ratio.When the saplings grew, their characteristics were determined and the effects of applied factors on these characters were evaluated statistically. Later by settings field trial, relation between the characteristics of saplings and their field adaptation capability was examined.

Title: Assessment of Efficiency Levels of Forest Enterprises using Classical and Fuzzy Data Envelopment Analysis (A Case Study: Denizli, İzmir and Muğla Regional Directorates)

Bulletin Number .......  Izmir-2010

Authors: Dr. İsmail ŞAFAK

ABSTRACT:

In this study, activities of 26 forest enterprises in the Aegean Region during the 2005-2007 periods were investigated and evaluated using traditional and fuzzy data envelopment analysis techniques and efficiency levels.Efficiency scores of the forestry enterprises of Aegean Region were determined using traditional data envelopment analysis solutions and then required levels of input and output to maintain efficacy of forest enterprises which are not efficient for every decision or activity are calculated.Fuzzy data envelopment analysis solutions were realized by using interval data. In this context, fuzzy data were generated by defining lower, central (median) and upper bound in the base of triangle membership function. These data were transformed into interval data considering α cut sets approach after Zimmermann (1991). Thus, lower and upper efficiency bound values were determined at three different α cut levels (0.30, 0.50 and 0.70). Consequently, inefficient forest enterprises were ranked from the best to the worst using minimax regret-based approach.

Authors: Dr. İ. Meltem Özçankaya, Dr. Saide Nafisi Balay, Muhammet Kılcı, Cemhan Bucak

ABSTRACT:

In the study, determination of biotic factors and nutrients on conalet losses of stone pine in sampling areas in private forests in Kozak was aimed. In the study it was determined that almost all cone losses occured in new conalets. According to the assesments, significant differences were found between years and regions in the cone losses. Smaller needle size, lessen fresh and dry weight and increased cone losses. By the examination of relation between cone losses and the plant nutrients (macro and micro) in needle, a negative relationship between cone losses and nitrogen, phosphorus, calcium and manganese have been determined. Some pests and diseases of needle and cones have been determined in the whole sampling areas. But none of them could cause significant cone loss.
