TIBBİ VE AROMATİK BİTKİLER
A Training Project for Sustainable Wild Harvest and Postharvest Practices of MAPs in Antalya Prof. Dr. Kenan TURGUT Akdeniz University Faculty of Agriculture Department of Field Crops Antalya E-mail: kturgut@akdeniz.edu.tr This is also Antalya! Turkey exports approximately 12.000-13.000 tonnes of oregano each year and almost 20% are wild crafted. 8.000-9.000 tonnes of laurel are exported each year and all of them are wild crafted. 1.500-2.000 tonnes of sage are exported each year and most of them are wild crafted. MAPs in the Flora of Antalya Natural flora of Antalya is very rich and diverse. Thus, that attracts the herb traders & exporters, and essential oils producers. There are 124 Families, 642 Genus, 1916 Species, 2078 Taxons in the flora of Antalya. 8 Origanum species (4 endemic), 7 Thymus species (2 endemic), 17 Salvia species (5 endemic), 15 Sideritis species (10 endemic) are grown in the flora of Antalya. MAPs in the Flora of Antalya Local people in Antalya consume herbal teas made from Sideritis, Salvia and Origanum species for their health. In the villages, some wild plants are used as healing medicine and antiseptics, for sore throat, stomach pains etc. There are number of essential oil producers and culinary herbs companies in Antalya. Mainly, as oregano species Origanum onites, O. majorana (O. dubium ref. Lukas et.al. 2013), O. minutiflorum, O. vulgara subsp hirtum; as sage species Salvia fruticosa, S. tomentosa; as mountain tea Sideritis congesta, S. stricta etc and Laurus nobilis are harvested commercially from the wild flora of Antalya. Those drogs are used for production of essential oil, culinary herbs and herbal tea. Antalya is one of the most important province in terms of wild crafting, cultivation and processing (EOs & herbs) of MAPs. Although, cultivation of MAPs seems very attractive recent years, most of the MAPs are still harvested from the natural flora of Antalya. Wild crafting practices are operated by the local people of various locations. However, many mistakes are done during harvest and postharvest applications. As a result, great yield and quality losses are occured. Aim of the Project: The aim of the Project is to prevent the losses of yield and quality of wild MAPs by improving the harvest and postharvest processes and to raise public awareness for conservation of wild MAPs. Oregano (Origanum spp.), sage (Salvia spp.) and laurel (Laurus nobilis) were included in the project. They are the most harvested species from the natural flora of Antalya and take place in the first rows of our exports on aromatic plants. For those aims, training activities were done. and demonstration Supporter Organizations of the Project The project was proposed by Antalya Commodity Exchange and financially supported by the Ministry of Food, Agriculture and Livestock, General Directorate of Agricultural Research and Policy State Organizations Antalya Commodity Exchange (Project Coordination) Akdeniz University Antalya Regional Directorate of Forestry Batı Akdeniz Agricultural Research Institute Private Companies İnan Tarım (Essential Oils, Herbs) WBT A.Ş.

Manavgat: Sırtköy, Sevinçköy,Yaylaalan, Tilkiler, Salur köyleri Training Center:Yaylaalan köyü Alanya: Sapadere,Yayla konak, Beldibi, Güzelbağ, Bayırköy köyleri Training Center: Sapadere, Güzelbağ köyleri Gazipaşa: Kahyalar, Çalıpınar, Karatepe, Karalar, İnal ve Çile köyleri Training Center: Kahyalar. Selected Project Locations Printed Materials Initially, posters, brochures and leaflets were prepared and printed in order to distribute to trainees and all stakeholders. This was very important for creating public awareness for wild crafting of MAPs Printed Poster Printed Brochure Printed Brochure Firstly, District Governors of Alanya, Gazipaşa and Manavgat were visited and informed about the project. They expressed their sincere supports. Secondly, the project was introduced to the village headmen, chairmen and board members of MAP cooperatives, MAP traders and other stakeholders in three towns. Also, first questionnaires were asked to all participants after the meetings. Journalists were invited to all meetings in order to create public awareness. Experimental Samples Drog samples were taken from harvesters (villagers) and traders for chemical analyses, phytopathological and other tests. Drog samples were classified as early and right time harvested; dried under the sun and shade; stored in well-ventilated and poor ventilated rooms. They were compared to each other in terms of volatile oil content . Volatile oil analyses (GC-MS) were done by BATEM, phytopathological and other tests were done by Agriculture Faculty of Akdeniz University. Oregano samples were taken as fresh, after drying and after threshing for EO analyses. Fresh, dried and threshed samples gave 0.91%, 1.05% and 0.85% EO rates, respectively. Normally, after drying of fresh samples with 0.91% EO rate, should give at least 2.5%. After threshing, this rate drop to 0.85%. These results show that inadequate drying and thresing methods reduce EO rates of the drogs almost 40%. In sage, very early harvested samples gave 0.26% EO rate, right time harvested samples gave 1.14% EO rate. Sun dried laurel samples gave 2.56% EO rate, shade dried samples gave 3.57% EO rate. The most important problems during harvest and postharvest application of wild MAPs Lack of knowledge on importance of biodiversity, endemic plants, in situ conservation etc. Commercial plant populations are harvested every year without any rotation. This cause decrease of populations. There are several good examples (3 years rotations) only for laurel harvest. Inconvinient harvest practices (pulling herbaceous plants with their roots instead of cutting). Laurel rehabilitation area in Yaylaalan, Manavgat (2006-2010) Harvesting mixed plant materials (different plants, different development stages etc.) Early harvest except laurel. Villagers often collect the plants long before flowering stage due to competition and fire season restriction. Inadequate and unhygienic transport, drying, threshing and storage applications. Yeniköy, Gazipaşa Bayırköy, Alanya Laurel harvest using brush hooks After cutting of laurel braches Transportation and Drying of Laurel Due to inadequate harvest and postharvest applications, amount of product and also quality of drogs are decreased significantly. As a result, the products are lost their values. In drogs; physical and chemical deteriorations, microbiological contaminations, mixture of other materials and different plants were observed. Naturally, these problems effect domestic consumers and exportation of MAPs. TRAINING PROGRAM 1.

Good and Hygienic Postharvest Applications (6 h) 4.1 Transportation, drying, threshing and storage of MAPs 4.2 Importance of hygienic production Total: 30 Hours (14 h theoretic + 16 h practical training) Tools were distributed to the trainees Sickles (harvesting oregano, sage etc.) Protective gloves Pruning shears (harvesting laurel and looks promising) Drying tables (made from steel) Hats Benefit Analysis in 2nd year 6 91.1 5 95.6 4 84.4 3 82.2 2 91.1 1 82.2 75 80 85 90 95 100 1 Theoretic Training, 2 Applied Training, 3 Booklet, 4 Brochures, 5 Tools, 6 Total Project Conclusion Public awareness on conservation of MAPs was raised in pilot locations, may be in other locations, Good and sustainable harvesting methods were taught, Appropriate drying of MAPs were taught, but some laurel locations need drying systems because of seasonal rains. Threshing is still problem! They need suitable and simple threshing machines, Storage conditions of drogs were improved, This project revealed that it is always possible to increase quality and yield of wild crafted MAPs by the training activities. This kind of training projects should be continued by the Department of Non-Wood Forest Products and Services for other locations as well. THANK YOU FOR YOUR ATTENTION
