Abstract
Tarımda ürün eldesi sırasında meydana gelen ekonomik kayıpları azaltmak için uzun yıllardır kullanılan kimyasal yöntemler,insan sağlığı ve ekolojik dengeyi olumsuz etkilemektedir. Bu nedenle son yıllarda çevreye zararsız iyileştirme yöntemleri ileilgili araştırmalar artmıştır. Kimyasal ürünlere alternatif olarak tercih edilen doğal iyileştiricilerden birisi de kitosandı r.Kitosan, çoğunlukla yengeç, ıstakoz, karides gibi kabuklu su canlılarının iskeletinde yaygın olarak bulunan kitindendeasetilasyon yöntemiyle elde edilmektedir. Kitosan antiviral, antibakteriyel ve antifungal özelliğe sahip olmasının yanında,bitkilerin savunma sistemini de teşvik ederek hastalıkların kontrolü ve yayılmalarının azaltılmasında da etkili bir ajandır.Bunun yanında bulunduğu ortamda (su, toprak vb.) metal iyonlarını şelatlaması ve bitkilerin toksik etkili metallerin alınımınıengellemesi nedeniyle tarım alanında iyileştirmede de kullanılmaya başlanmıştır. Yapılan çok sayıdaki çalışmaya rağmenkitosanın bitkilerdeki etki mekanizması tam olarak aydınlatılamamıştır. Kitosanla ilgili detaylı çalışmaların artması, tarımsalalanlarda kitosan kullanımı ile ürünlerden yüksek verim alınabilmesi için yardımcı olacaktır.
Chemical methods that have been used for many years to reduce the economic losses during agricultural production have an_x000D_ adverse effect on human health and ecological balance. Therefore, in recent years, researches about harmless environmental_x000D_ improvement methods have increased. One of the preferred natural conditioners as an alternative to chemical products is_x000D_ chitosan. Chitosan is obtained from the chitin deacetylation method, which is commonly found in the skeleton of shellfish_x000D_ such as crab, lobster, shrimp. Besides having antiviral, antibacterial and antifungal properties, chitosan is an effective agent_x000D_ in controlling and reducing the spread of diseases by promoting the defense system of plants. In addition to this, it has been_x000D_ started to be used in the agricultural field as it chelates metal ions in its environment (water, soil, etc.) and prevents the_x000D_ ingestion of toxic effective metals by the plants. Despite many studies, the mechanism of action of chitosan in plants has not_x000D_ been fully elucidated. The increase in detailed studies on chitosan will help to obtain high yields of products with the use of_x000D_ chitosan in agricultural fields.
