Bu çalışma, 2005 yılı Ekim ve 2006 yılı Nisan ayları arasında Batı Akdeniz Tarımsal
Araştırma Enstitüsü’nde, topraksız kültürde farklı tuzlu su düzeylerinin serada yetiştirilen
Frezya süs bitkisinin çiçeklenme, çiçek kalitesi ve yumru verimi üzerine etkilerinin
belirlenmesi amacıyla yürütülmüştür. Çalışmada, Oberon, Athena ve Cordula olmak
üzere üç farklı çeşit kullanılmıştır. Dört farklı tuz düzeyi (EC1 =1,5 dS m-1 (kontrol),
EC2= 3,0 dS m-1, EC3 =4,5 dS m-1 ve EC4 =6,0 dS m-1) NaCl kullanılarak sağlanmıştır.
Tuzlu sulama suyu uygulamalarının tüm Frezya çeşitlerinde yumru, yumrucuk, çiçek
verimi, çiçek sapı uzunluğu, çiçek sapı kalınlığı, çiçek sayısı ve başak uzunluğunu
azalttığı belirlenmiştir. Tuzluluk eşik değeri Athena, Oberon ve Cordula frezya çeşitleri
için sırasıyla 2,7, 1,0 ve 3,0 dS m-1 olarak belirlenmiştir.

Effects of saline irrigation water applications on quality characteristics of freesia grown in greenhouse

Öz

This study was carried out in soilless culture to determine the effects of saline irrigation levels on flowering and flower quality of Freesia hybrids planted in a plastic greenhouse located in Bati Akdeniz Agricultural Research Institute between October 2005 and April 2006 under Mediterranean conditions. In the study, three freesia varieties, Oberon, Athena and Cordula corms were used. Four salinity levels, EC1 =1.5 dS m-1 (control), EC2= 3.0 dS m-1, EC3 =4.5 dS m-1 and EC4 =6.0 dS m-1, were applied using NaCl. It was found that saline irrigation water levels decreased the corm, cormel and flower yield, flower stem length and diameter, flower numbers and flower spike length in all freesia varieties studied. The threshold values for Athena, Oberon, and Cordula varieties were determined to be 2.7, 1.0, and 3.0 dS m-1, respectively.
