Türkiye’nin Bazı Gypsophila L. (Caryophyllaceae) Taksonlarının Habitat Özellikleri

Abstract

"Gypsophila" is a name of a plants group which is adapted to the gypsum environments. It is the third largest genus of Caryophyllaceae
family in Turkey. 60 taxa belonging to 56 species grow naturally in Turkey and 35 of them are endemic (respectively endemism rate of about
60%) In our country, the members of the genus is commonly known as "Coven". Because of Turkey is gene center of Gypsophila which is
indicator of gypsium areas and is economically very valuable, the introduction of the biological characteristics of Gypsophila taxa is very
necessery. In this study, physical and chemical properties of the soil samples taken from the natural habitats of Gypsophila L. genus growing in
Turkey were determined. After that the results obtained from the analyses are interpreted. In addition some field properties and ecological
characteristics of the taxa were given. Soil samples of the species are rough textured, alkali, saltless and limed in very high and medium level.
The amounts of sodium, magnesium, phosphorus and zinc are low. Iron and cupper amounts are low and medium, the levels of organic matter
and potassium are medium and rich, calcium are high. Gypsophila taxa have distribution between 100 and 2800 m altitudes in Turkey. Most of
the studied soil samples are gypseous. This type of fields are poor in terms of higher plants and susceptible to erosion. Because of their well
developed root structure, they prevent erosion.
