Bu çalışma, Antalya yöresinden toplanan 2’si endemik toplam 12 Akyıldız (Ornithogalum L.)
türünde farklı sulama suyu seviyelerinin soğan gelişimi, yavru soğan oluşumu ve çiçeklenme
üzerine etkilerinin belirlenmesi amacıyla yürütülmüştür. Çalışmada doğal ortamlarından
toplanan soğanlar, koyu gölge perdesi ile korunmalı cam sera koşullarındaki topraksız kültür
ortamına (1:1 hacimsel torf: perlit karışımlı) dikildikten sonra 3 farklı sulama seviyesinde (S1:
susuz, S2:1 litre bitki-1 hafta-1 ve S3: 2 litre bitki-1 hafta-1) yetiştirilmişlerdir. Deneme süresince
çiçek sapı uzunluğu, salkımdaki çiçek sayısı, soğan çapı ve ağırlığı, yavru soğan sayısı ve
ağırlığına ilişkin gözlem ve ölçümler yapılmıştır. Sonuçlar, farklı sulama uygulamalarının,
incelenen özellikleri istatistiksel anlamda önemli düzeyde etkilediğini göstermiştir. Kontrol
(sulanmayan) bitkileri ile karşılaştırıldığında; diğer sulama seviyelerinin soğan çap ve ağırlığı,
yavru soğan sayısı ve ağırlığı ile çiçek sapı uzunluğu ve çiçek sayısında artışlarla sonuçlandığı,
ancak türlerin sulama seviyelerine tepkilerinin farklılık gösterdiği belirlenmiştir.

The effects of different irrigation levels on bulb development and flowering of native Ornithogalum species

Öz

The study was conducted to quantify the effect of different irrigation levels on bulb growth, bulblet formation and flowering of 12 native Ornithogalum L. species, two of them endemic, gathered in Antalya region. Bulbs collected from native environments were planted in soilless culture (1:1; peat: perlite, v:v) in greenhouse, that is protected with dark shadow material. Three different irrigation levels (S1: no irrigation, S2: 1 liter plant-1 week-1 and S3: 2 liters plant-1 week-1) were applied, and data related to flower stem length, flower number per spike, bulb diameter and weight and bulblet number and weight was collected during the experiment and analyzed. The results revealed that irrigation treatments had significant effects on characteristics considered in this study. In general, irrigation levels S2 and S3 resulted in significant increases in flower stem length, flower number per spike, bulb diameter and weight and bulblet number and weight compared to the control (no irrigation) treatment. However responses of species to irrigation levels showed significant differences.
