Rosularia globulariifolia var. pallidiflora comb. et stat. nov. (Crassulaceae)

Nordic Journal of Botany (2012)

Ersin Minareci Kemal Yıldız Salih Gücel Mehmet Kuh

Rosularia globulariifolia (Fenzl) A. Berger and R. pallidiflora (Holmboe) Meikle were originally described as species in Umbilicus DC. in 1842 and 1914, respectively. In the present study, morphological and palynological features were examined in detail to determine the status of these taxa. The general characteristics, seed structure and micromorphology, pollen measurements and pollen characteristics were established. Morphologically, the two taxa cannot easily be distinguished. Pollen grains of both species are tricolporate, subspheroidal and eutectate, ornamentation is psilate and exine structures are similar. Based on morphological and palynological similarities, and the fact that both taxa are found in the same habitats, we propose that R. pallidiflora should be reduced to the rank of variety as Rosularia globulariifolia (Fenzl) A. Berger var. pallidiflora (Meikle) Minareci & K. Yildiz comb. et stat. nov.

Türkiye'de yetişen bazı Silene L. türlerinin toprak özellikleri

Biyolojik Çeşitlilik ve Koruma (2020)

Kemal Yıldız Mehmet Kuh Seçil Tan Güngör Ay

Turkiye florasi’nda yetisen Italicae (Rohrb.) Schischk. Giganteae Du Pasquier, Siphonomorpha Otth, Lasiostemones Boiss., Sclerocalycinae Boiss., Chloranthae Rohrb., Tataricae Chowdhuri, and Otites (Adams.) Otth seksiyonlarina ait 19 (21 takson) Silene L. (Caryophyllaceae) turunun toprak ozellikleri arastirilmistir. Incelenen toprak ozellikleri; fiziksel karekter olarak, suya doygunluk (%), kimyasal karekter olarak ise tuz (%), organik madde (%), kirec (%) oranlari, pH (toprak reaksiyonu) degeri, fosfor (P), potasyum (K), magnezyum (Mg) ve kalsiyum (Ca) miktarlari (ppm) olmustur. Silene taksonlarinin ornekleri toplanmis ve bu alanlardan, 10-30 cm derinlikteki toprak ornegi alinmistir. Toprak reaksiyonu (pH) “cam elektrotlu pH metre” ile, elektrik iletkenlik (ECX103) “Conductance Bridge” aletinde, topraklarin tane caplari “Bouyoucos’un hidrometre yontemi”ne gore, topraktaki fosfor (P) “Bray ve Kurtz No. 1” yontemine gore, alkalen reaksionlu topraklarda “Olsen” yontemine gore, topraktaki potasyum (K), kalsiyum (Ca), Magnezyum (Mg) tayini “amonyum asetat yontemine gore yapilmistir. Yaptigimiz arastirmada, taksonlarin yetistigi topraklarin, killi, tinli, killi-tinli, taksonlarin cogunun hafif alkali, tamaminin tuzsuz, organik madde degerlerinin cok dusuk ve yuksek, kirecsiz ve cok kirecli, orta-iyi oranda fosfor (P), dusuk-yuksek oranda potasyum (K), zayif-orta miktarda kalsiyum, zayif-cok yuksek oranda ise magnezyuma (Mg) sahip topraklarda yetistigi tespit edilmistir. Incelenen Silene taksonlarinin lokal olanlar endemikler disinda, Turkiye’nin cok degisik toprak ozelliklerine sahip alanlarda yetisme ozelligine sahip olduklari gorulmustur.

A taxonomic study of the Silene sections Behenantha and Dichotomae (Caryophyllaceae) in Turkey based on the micromorphology of their seed and pollen

TURKISH JOURNAL OF BOTANY (2017)

Mehmet Kuh Kemal Yıldız Ersin MİNARECİ

The seed and pollen grain micromorphologies of 10 taxa of the Silene sections Behenantha and Dichotomae (Caryophyllaceae) were analyzed in this study. Although the seeds of the analyzed taxa were generally reniform, S. tenuiflora and S. koycegizensis from the section Behenantha were clearly distinct from other taxa, while subspecies of S. dichotoma and S. euxina in the section Dichotomae showed differences. Pollen grains are periporate and spheroidal and ornamentation is generally spinulate-microperforate in all taxa. However, ornamentation is spinulate in S. euxina and semireticulate in S. koycegizensis. While the exine structure is generally tectate, it is semitectate in S. koycegizensis. It was found that S. heldreichii and S. cariensis subsp. muglae had the highest number of pores, while S. dichotoma subsp. racemosa had the lowest number of pores. The results showed that S. euxina can be distinguished from S. dichotoma based on morphological characteristics of their pollen grains and seeds.
