This study was planned to research the utilization possibilities of particle film technology described as kaolin applications in order to prevent yield and quality losses resulting from stress conditions such as temperature, radiation and drought or late spring frosts.
Applications of kaolin was carried out under either the conditions of traditional apricot cultivation or the conditions of non-irrigated in apricots cultivation on Hacıhaliloğlu variety. In the study, the effectiveness of 3%, 5%, 6% doses kaolin applications at different vegetative and generative periods on yield and quality criteria (fruit size, firmness, total soluble solids (TSS), pH, total acidity and color values) of apricot, the amount of chlorophyll in leaf, total carotenoids in fruits and protective activity of kaolin against the late spring frosts occurring during buds and small fruits period were assessed. The results are important to farmers and applicable.

Use of Natural substances to improve THE quality and quantity of Local apricot variety IN malatya
Hacialioglu is local and traditional variety from Province of Malatya. This province is suitable for dry apricot production because of its climatic conditions. This product has an important economic value for the province and by its nutritional value it is very healthy for people. Kaolin application was done in order to prevent the yield and quality losses that are caused by abiotic stress conditions and late spring frosts. When applied kaolin covers the crown and protects buds from chilling injury.
Malatya is located in Central Anatolia Region where climatic conditions can be described as hot-dry summers and cold-snowy winters. This climatic conditions make this province very suitable for apricot cultivation. While cold winters let apricots to meet their chilling requirements, hot summers improves the quality of apricots. Hacihaliloglu local variety is well adapted to this climatic conditions. But on early spring frost may cause loss of yields because of chilling injury. It is economically important because the dried apricots are exported. From a cultural point of view it can be said that the product is a representative of Malatya, therefore Turkey to whole world. Because 92% of the dried apricots of the world are being supplied from this region only. From socially point of view, it contributes the rural development by contributing rural economy and households economically.
By the use of kaolin, the apricots are protected from frosts. Protection leads an increase and improvement both in terms of quality and quantity. Kaolin can be used safely in regions where it is not possible to cultivate stone fruit, due to low temperature. The well qualified product preserves consumer health and it provides growers stable income. As a result, rural communities are developed socially and economically.
Both apricot growers and apricot consumers are the real beneficiaries of the project. Growers, can use it to protect their yields from cold damage easily while consumers are having higher quality product.
This work was carried out by Apricot Research Directory, Olive and Olive oil Research Directory and The Foundation for Apricot Research, Development and Promotion(NGO).
This work was carried out by Handan ATAOL ÖLMEZ from Olive and Olive Oil Reseach Directrory; Belgin Celik and Kadir Celık from Apricot Research Directory. Results were evaluated together. Financial part of the project was covered by a NGO.
On the risky orchards in terms of cold damage, pre-harvest application of kaolin might leave residues on fruits. Kaolin use is recommended at early fruit development stage in order to prevent this residue problem. Washing with pressurized water can be also done in order to clean visible residues from surface of fruits. In arid conditions kaolin application following harvest would improve the quality of products and increase yields without cold damage protection.
There are three application periods for kaolin. Kaolin that is applied to the fruit in the second period will protect the fruit from low temperature also problem of residue will be lower by washing fruit with water. In the third application residue level will increase but it has positive effect on fruit quality. Application in this period helps to increase Carotenoid level and nutritional value. Kaolin applied to the trees after harvesting the fruits, will improve quality and quantity for the next season.
This local variety is cultivated according to organic agriculture without using any synthetic products such as pesticides and fertilizers. In this way, human health and environment are preserved. Also local variety belonging to this area is protected; Genetic erosion is prevented.
This local variety represents an example to other local varieties on the basis of the preservation of the product. By the use of kaolin, the apricots are not affected by spring frosts. Also, yield and quality become constant. This application can also be applied to different species which are sensitive to spring frosts such as almond, cherry etc. Kaolin is capable to save water into plant tissues so it can be used in dry conditions.
There have been published broschure and an article on agricultural bulletin 'Malatya Tarım Bülteni'.
