Özet
Bu çalışma Atatürk Bahçe Kültürleri Merkez Araştırma Enstitüsü (ABKMAE)’nde 2008-2009 yıllarında 5 yerli (Alyanak Hulu, Bayramiç Tüysüzü, Sapanca, Takunyacı-I ve Sarı Papa) ve 7 yabancı (Glohaven, Elegant Lady, Monroe, Rio Oso Gem, Fortuna, Jungerman ve Vivian) olmak üzere 12 şeftali/nektarin çeşit ve tipinin çiçek tozlarının canlılık ve çimlenme durumlarının belirlenmesi amacıyla gerçekleştirilmiştir. İyotlu Potasyum İyodür (IKI) ve 2,3,5 Triphenyl Tetrazolium Chlorid (TTC) boyama testleri ile canlılık ve “doymuş petri” yöntemiyle in vitro çimlenme durumları, ayrıca çiçek tozlarının homojenliği (benzerlik) belirlenmiştir. 2008 yılı ortalamasına göre, incelenen özellikler bakımından önemli farklılıklar ortaya çıkmıştır. IKI testinde %64.26-87.08; TTC’de %60.94-81.27; çimlenme oranı %52.12-74.27 ve morfolojik benzerlik ise %43.59-99.11 arasında değişim göstermiştir. 2009 yılında IKI testi ile morfolojik homojenlik değerleri bakımından çeşitler arasında farklılık bulunmuş, TTC ve çimlenme testlerinde ise fark ortaya çıkmamıştır. Çiçek tozu homojenliği bakımından her iki yılda da en düşük değer Sapanca tipinde bulunmuştur. Araştırma sonucunda, çiçek tozlarının canlılık ile çimlenme oranları arasında pozitif ilişki olduğu, homojenlik artışına paralel olarak canlılık ve çimlenme oranının da arttığı belirlenmiştir.
The aim of this study which was conducted out in the Atatürk Central Horticultural Research Institute in the years 2008 and 2009 was to investigate the pollen viability and the germination of five local types (Alyanak Hulu, Bayramiç Tüysüzü, Sapanca, Takunyacı-I and Sarı Papa) and seven foreign (Glohaven, Elegant Lady, Monroe, Rio Oso Gem, Fortuna, Jungerman and Vivian) peach cultivars. the rate of pollen viability was determined by Iodine/Potassium iodide solution (IKI) and 2,3,5 Triphenyl tetrazolium chloride (TTC); agar-plate test was used to determine the rate of pollen germination in vitro. Morphological homogeneity of pollen was also evaluated. According to the mean of the year 2008, the rates of pollen viability and germination and morphological homogeneity varied significantly between cultivars, and was also found the differences between two staining tests. Pollen viability in IKI and TTC staining tests, germination and morphological homogeneity of pollen were ranged between 87.08%- 64.26% and 81.28%- 60.94%, 52.12%- 74.27% and 43.59%- 99.11% respectively. in 2009, only IKI test and morphological homogeneity of pollen varied significantly, the others were not found significant. According to the rate of morphological homogeneity, Sapanca was the worst of all cultivars and types. Consequently, positive correlation was found between the rates of pollen viability and germination, and these rates increased when morphological homogeneity of pollens rises.
