Özet:

 In water deficit areas, existing stressors are becoming more severe with climate change. Therefore, the aim of this study was to determine the effects of plant supportive treatments mycorrhiza, polymer, osmoprotectant, polymer  osmoprotectant on the water stress of seedlings to increase the drought resistance of plants in an area with severe water deficit during the growth period. 1  1 Russian olive Elaeagnus angustifolia L. seedlings were planted without irrigation in the study area located in the campus area of Izmir Kâtip Çelebi University. In the study, survival rates, diameter and height values, relative growth rates of root collar diameter and shoot height and changes in soil moisture were determined. Although mycorrhiza, polymer and osmoprotectant treatments did not help the seedlings to survive the period of record-breaking temperatures, they were able to extend their survival by two months. In July, when soil moisture levels were the lowest, the polymer and mycorrhiza treatments were 73 higher than the control. Seedlings in mycorrhiza, polymer, osmoprotectant and polymerosmoprotectant units had about 23 thicker diameter and 73 more relative growth rates of root collar diameter than the control. Seedlings in polymer and osmoprotectant units were about 47 taller than the control, mycorrhiza and polymerosmoprotectant units. Compared to the control, the seedlings in the other units realized two times more relative growth rates of shoot height.

 Su açığı bulunan sahalarda iklim değişikliği ile birlikte var olan stres faktörleri daha da şiddetli hale gelmektedir. Bu çalışmanın amacı büyüme döneminde şiddetli su açığı gerçekleşen alanda bitkilerin kuraklığa karşı direncini arttıracak bitki destekleyici işlemlerin mikoriza, polimer, osmoprotektan, polimer  osmoprotektan fidanların arazi performansına olan etkilerinin belirlenmesidir. İzmir Kâtip Çelebi Üniversitesi kampüs alanında yer alan çalışma sahasına sulama yapılmaksızın 11 yaşlı iğde Elaeagnus angustifolia L. fidanları dikilmiştir. Çalışmada fidanların yaşama oranları, çap ve boy değerleri, nispi çap ve boy artımları ve toprak nemindeki değişimler tespit edilmiştir. Mikoriza, polimer, osmoprotektan uygulamaları, fidanların sıcaklık rekorlarının kırıldığı dönemi atlatmasını sağlayamasa da hayatta kalma sürelerini iki ay uzatılabilmiştir. Toprak neminin en düşük olduğu Temmuz ayında polimer ve mikoriza ünitesindeki nem değerleri kontrol ünitesindekine göre 73 daha fazla ölçülmüştür. Mikoriza, polimer, osmoprotektan ve polimerosmoprotektan ünitelerindeki fidanların kontrole göre yaklaşık 23 daha kalın çapa sahip oldukları ve 73 daha fazla çap artışı gerçekleştirdikleri tespit edilmiştir. Polimer ve osmoprotektan ünitelerindeki fidanların boyunun kontrol, mikoriza ve polimerosmoprotektan ünitelerine göre yaklaşık 47 daha uzun olduğu belirlenmiştir. Kontrole göre diğer ünitelerdeki fidanlar iki kat fazla nispi boy artımı gerçekleştirmiştir.
