Bu çalışmada, farklı su seviyeleri ile biyoaktivatör uygulamalarının Kabarla çeşidinde ekofizyolojik özellikler üzerine etkileri araştırılmıştır. Sulamalar; tam sulama IR100 konusu, uygulanacak suyun yarısının verileceği konu IR50, %75’inin verileceği konu IR75 ve %125’inin verileceği konu IR125 olarak adlandırılmıştır. Biyoaktivatör uygulamaları ise tam ve kontrol (biyoakivatörsüz) olarak uygulanmıştır. Tesadüf bloklarında bölünen bölünmüş parseller deneme desenine göre 4 yinelemeli olarak yürütülen araştırma sonucunda su stresinin (kısıntılı sulama) çilek bitkisinde ekofizyolojik özellikleri olumsuz etkilediği gözlenmiştir. En yüksek stoma iletkenliği ve yaprak su potansiyeli değerleri IR125 uygulamasından elde edilirken, en düşük değerler ise IR50 uygulamalarından elde edilmiş olup, uygulamalar arasındaki farklar istatistiksel olarak anlamlı bulunmuştur. Biyoaktivatör kullanımının çilek bitkisi ekofizyolojik özelliklerini olumlu etkiledikleri görülürken istatistiksel anlamda da önemli bulunmuştur. Biyoaktivatör kullanılmayan konularda ekofizyolojik özellikler genelde düşüş gösterse de su stresi ile birlikte çoklu stres olarak (su × biyoaktivatör) bitki ekofizyolojik özellikleri üzerine etkisi istatistiksel olarak anlamlı bulunmamıştır. Çalışma sonuçları ışığında güçlü bir ekofizyolojik özellik için her ne kadar istatistiksel olarak fark belirlenememişse de, su ve biyoaktivatör etkileşiminden elde edilecek kombinasyonun kullanılması bitki su kullanım etkinliğini arttırmasından dolayı önerilebilir.

Effects of Different Irrigation Levels with Bioactivator Applications on Ecophysicological Characteristics in Strawberry

Öz

In this study, the effects of different irrigation levels with bio activator applications on the ecophysicological characteristics in a variety of Kabarla were investigated. Strawberry plant was subjected to four irrigation water levels (IR125, 1.25 Ep; IR100, 1.0 Ep; IR75, 0.75 Ep; IR50, 0.50 Ep). Bioactivator applications were conducted as full and without bioactivator. As a result of the study, planned as randomized complete block split split plot design with four replications, it was observed water stress affected ecophysicological characteristics adversely. The highest stomatal conductance and leaf water potential were obtained from the IR125, whereas the lowest values were obtained from the IR50 (deficient irrigation) and also the differences between applications found to be statistically significant. Furthermore, the use of bioactivator on the strawberry plant, ecophysicological parameters were observed to affected positively as statistically significantly. Subjects which unused bioactivator were generally observed to decrease the ecophysicological characteristics, besides, they were also not found to be statistically significant on ecophysicological characteristics as multiple stress (applications × irrigation interaction). In the light of the study, it can be advised that the combination obtained from bioactivator × irrigation interaction for improved water use efficiency, although this was not validated statistically.
