Topraksız çilek yetiştiriciliğinde mikoriza ve yetiştirme ortamı hacminin bitki gelişimi üzerine etkileri

Topraksız çilek yetiştiriciliğinde kullanılan yetiştirme ortamı türü, bitki başına düşen hacim, bitki besin solüsyonları ve dışarıdan uygulanan bazı preparatlar gibi birçok kültürel uygulama, bitki büyüme ve gelişmesi ile verim ve kaliteyi önemli derecede etkilemektedir. Özellikle mikoriza uygulamaları birçok bitki türünde topraklı ve topraksız koşullarda verim ve kaliteyi artırıcı uygulamalar olarak kullanılmaktadır. Bu çalışma, kısıtlı yetiştirme ortamı hacimlerinde yetiştirilen çileklerde mikoriza uygulamasının bitki gelişimi üzerine etkilerinin belirlenmesi amacıyla gerçekleştirilmiştir. Çalışmada, ‘Festival’ çilek çeşidinde, iki farklı yetiştirme ortamı hacminde (2.75 ve 3.60 L·bitki-1), mikoriza uygulamalarının (mikoriza + ve mikoriza -) bitki gelişimi ve meyve kalitesi üzerine etkileri incelenmiştir. Araştırma sonucunda, mikoriza (+) uygulaması bitkilerde gövde çapı, yaprak sayısı, klorofil indeksi ve meyve sertliğini artırırken, meyve boyutlarını azaltmıştır. Morfo-fizyolojik özellikler bakımından yetiştirme ortamı hacmi arasında önemli farklılıklar bulunmamış olup, 3.60 litre bitki hacminde en yüksek meyve sertliği ve meyve iriliği belirlenmiştir. Uygulamalar suda çözünebilir kuru madde içeriğini etkilememiştir. Meyvelerde renklenme bakımından mikorizasız uygulamalar daha parlak (L) meyveleri oluştururken, mikoriza uygulaması yaprak rengini etkilememiştir.

Anahtar Kelimeler:

Many cultural factors such as soilless media type, volume per plant, plant nutrient solutions and exogenous some preparations are effective on plant growth and development,yield, quality of strawberries grown in soilless conditions. In particular, mycorrhiza applications are used in many plant species as applications to increase yield and quality in soil and soilless cultivation. In this study, the effects of mycorrhiza application on plant growth in strawberries grown in restricted root volume were investigated. In the research, the effects of two treatments (mycorrhiza + and mycorrhiza -) and two different soilless media volume (2.75 and 3.60 L plant) on plant growth and fruit quality were investigated in Festival strawberry cultivar. The result of the study, mycorrhiza application increased the crown diameter, leaf numbers, chlorophyll index and fruit firmness, while fruit size was decreased. In terms of morpho-physiological features, no significant differences were found between soilless medias volume, however, the highest fruit firmness and fruit size were determined at 3.60 L plant volume. The mycorrhizal application did not affect the soluble solid content. In terms of colour, the highest fruit lightness (L) was determined non-mycorrhizal application, whereas leaf colour did not affect from the mycorrhizal application.
