Amaç: Bu çalışmanın amacı Türkiye'nin güneyinde yetişen nadir endemik bir çalı türü olan Salvia dorystoechas'ın tohum özelliklerini belirlemektir.
Metod: Çalışmada iki tohum kaynağı kullanılmıştır: (1) Antalya - Feslikan Yaylası'ndaki doğal popülasyondan ve (2) Eskişehir Orman Fidanlığı'nda yetiştirilen Feslikan kökenli 3 yaşındaki Salvia dorystoechas bitkilerinden. Dormansiyi belirlemek için tohumlar dört farklı sürede katlama işlemine tabi tutulmuştur. Katlama işlemleri 4°C'de petri kaplarında nemli filtre kâğıdı üzerinde 2, 4 ve 6 hafta boyunca uygulanmıştır. Çimlenme testleri 20°C'de 12 cm çapındaki petri kaplarında filtre kâğıdı üzerinde 300 (3×100) tohumla gerçekleştirilmiştir.
Bulgular: Türün 1000-tohum ağırlığı 0,586 gr olarak belirlenmiştir. Tohumun şekli ince ve hafif içbükeydir. Tohumların ortalama uzunluğu, genişliği ve kalınlığı sırasıyla 4,29 mm, 1,57 mm ve 0,67 mm'dir. Tohum kabuğundan kaynaklanan fiziksel dormansi yoktur. Tohum, hafif derinlikte dormansiye sahiptir ve dormansiyi gidermek için 2 haftalık katlama işlemi yeterlidir. Herhangi bir ön işlem uygulanmayan tohumların (kontrol) çimlenme yüzdesi, toplam çimlenme kapasitesinin yarısını aşmaktadır. Çimlenme oldukça hızlı olup, katlama işlemlerinden sonra çimlenme yüzdesi bir hafta içinde maksimum seviyelere ulaşmaktadır.
Sonuç: Bu endemik ve dar dağılımlı türün tohum özellikleri ilk kez ayrıntılı olarak incelenmiştir. Çalışmanın türün tohumdan üretilmesine ve ex situ korunmasına katkıda bulunması beklenmektedir.
Purpose: The aim of this study was to determine the seed characteristics of Salvia dorysthoechas, a local endemic shrub growing in southern Türkiye.
Method: Two seed sources were used in the study: (1) from the natural population in Antalya - Feslikan Plateau and (2) from 3-year-old Salvia dorystoechas plants of Feslikan origin grown in Eskişehir Forest Nursery. In order to determine dormancy, seeds were subjected to four different duration of prechilling treatments. Prechilling treatments were applied to moist filter paper in petri dishes at 4°C for 2, 4 and 6 weeks. Germination tests were carried out using filter paper placed in 12 cm diameter petri dishes at 20°C with 300 (3×100) seeds.
Findings: 1000-seed weight was determined as 0.586 g. The shape of the thin seed was slightly concave. The average length, width and thickness of the seeds are 4.29 mm, 1.57 mm and 0.67 mm, respectively. There was no physical dormancy due to the impermeable seed coat. The seed has a physiological dormancy at a light depth and 2 weeks of prechilling treatment was sufficient to eliminate dormancy. The germination percentage of the seeds without any pretreatment (control) exceeds the half of the total germination capacity. Germination occurs rapidly and the germination percentage reaches maximum levels within a week after the prechilling treatments.
Conclusion: The seed characteristics of this endemic and narrowly distributed species were studied in detail for the first time. It is expected that this study will contribute to the production of the species from seed and the ex situ conservation.
