Lemnoideae alt familyasına ait türleri içeren sumercimekleri, çiçekli bitkilerin en
küçük grubunu oluşturmaktadır. Bu çalışmada Türkiye’nin önemli sulak
alanlarının bulunduğu bölgelerde sumercimeği türlerinin yayılış alanları ve
bazı ekolojik özellikleri araştırılmıştır. Sumercimeği genotiplerinin bulunduğu
lokasyonların koordinatları ArcGIS programı kullanılarak haritalandırılmıştır.
Sumercimeğigil üyesi 5 farklı türü temsil eden 67 genotipe ait bitki örneği
belirlenmiştir. Yapılan arazi çalışmalarında L. turionifera’ya ait 3 genotip; Spirodela polyrhiza’ya ait 4 genotip; Lemna trisulca’ya ait 7 genotip; Lemna gibba’ya ait 9 genotip ve Lemna minör’e ait 44 genotip
belirlenmiştir. Sumercimeği olduğu tespit edilen bölgelerin rakımları geniş bir
aralıkta (1-1734 m) bulunmuştur.  Model
bitki olarak değerlendirilebilmeleri, biyoremediasyon çalışmalarında kullanılma
potensiyelleri, içerdikleri yüksek protein içeriğinden dolayı balık ve diğer
hayvanlar için besin meateryali olarak kullanılabilmeleri ve içerdikleri yüksek
nişasta içeriğinden dolayı biyoyakıt olarak değerlendirilebilmeleri sumercimeklerinin
önemli avantajlarındandır. Bu anlamda ülkemizde yayılış alanları tür bazında
belirlenen sumercimeği üyesi bitkiler değerlendirilebilir.

Determination of the Duckweed Species in Turkey

Öz

The plants of the Lemnoideae subfamily are the
smallest group of flowering plants. In this study, the distribution areas of Lemnoidea
species in areas where important wetlands of Turkey and some ecological
characteristics were investigated. Coordinates of locations of duckweeds
genotypes are mapped with ArcGIS program. 67 genotype plant samples
representing 5 different species of duckweed members were identified. Three
genotypes belonging to L. turionifera
in the field studies; 4 genotypes belonging to S. polyrhiza; 7 genotypes belonging to Lemna trisulca. It was determined that 9 genotypes belong to L.gibba and 44 genotypes belong to L. minor. The altitudes of the areas
identified as duckweed were in a wide range (1-1734 m). Duckweeds are important
advantages: (1) they can be evaluated as a model plant, potentialities of use
in bioremediation studies, (2) they can be used as food for fish and other
animals due to the high protein content they contain and (3) they can be evaluated
as biofuels because they have high starch content. The duckweed member plants
whose distribution areas are determined in Turkey can be evaluated for these
purposes.
