Hypericum taxa of Turkey's flora and intra-population variation of morpho-agronomic traits in H. heterophyllum Vent., an endemic species

Öz

Hypericum L. belongs to the Clusiaceae (= Guttiferae) family. There are 98 species or 119 taxa of Hypericum, 49 of which are endemic in Turkey Flora, and the endemism ratio is 41.18%. Some of these species are used in various diseases externally/internally in the form of infusion, decoction, oleate or ointment in traditional treatment in Turkey. H. heteropyhllum is an endemic species that grows in arid, stony or rocky calcareous areas. In our study, the average plant height and number of branches were determined as 52.48±10.65 cm and 7.85±3.01, respectively in full flowering stage. The average length and width of the oval shaped seeds was 2.3220±0.1524 mm and 0.7933±0.0755 mm, respectively. Seeds of the plant is very small and average seed weight of 1000 seeds is 0.75975±0.0300 g. The highest fresh herb weight (587±251.91 g/plant) was obtained from plants collected at full flowering. The wide variation was observed especially in plant height and number of main branches in the measurements made on plants in the natural area.

Hypericum L., Clusiaceae (= Guttiferae) ailesinin bir üyesidir. Türkiye florasında 49'u endemik olmak üzere Hypericum' un 98 türü ve 119 taksonu bulunmaktadır. Endemizm oranı ise %41.18'dir. Bu türlerin bir kısmı Türkiye'de geleneksel tedavide infüzyon, dekoksiyon, oleat veya merhem şeklinde çeşitli hastalıklarda harici/dahili olarak kullanılmaktadır. H. heteropyhllum kurak, taşlı veya kayalık kalkerli alanlarda yetişen endemik bir türdür. Bu çalışmada tam çiçeklenme döneminde ortalama bitki boyu ve dal sayısı sırasıyla 52.48±10.65 cm ve 7.85±3.01 olarak belirlenmiştir. Oval şekilli tohumların ortalama uzunluğu ve genişliği ise 2.3220±0.1524 mm ve 0.7933 ± 0.0755 mm olarak belirlenmiştir. Bitkinin tohumları çok küçüktür ve 1000 tohumun ortalama tohum ağırlığı 0.75975±0.0300 gr'dır. En yüksek yaş herba ağırlığı (587±251.91 g/bitki) tam çiçeklenme döneminde toplanan bitkilerden elde edilmiştir. Doğal ortamlarında bitkiler üzerinde yapılan ölçümlerde özellikle bitki boyu ve ana dal sayısında geniş bir varyasyon gözlemlenmiştir.
