آنالیز کلادیستیک ریخت شناسی جنسهای calligonum و pteropyrum از تیره polygonaceae

21 تاکسون شامل 18 گونه calligonum و 3 گونه  pteropyrumبعنوان درون گروه به اضافه 2 گونه از atraphaxis، بعنوان برون گروه با استفاده از30 صفت ریخت شناسی مورد مطالعه قرار گرفتند. در هر دو آنالیز بدون وزن دهی و با وزن دهی (توسط شاخص سازگاری تصحیح شده)، calligonum و pteropyrum تشکیل کلاد مجزا داده اند. هر دو بخشه pterococcus و) calligonum  شامل بخشه تک گونه ای (calliphysa از جنس calligonum تک تبارند....

The Phylogeny of Calligonum and Pteropyrum (Polygonaceae) Based on Nuclear Ribosomal DNA ITS and Chloroplast trnL-F Sequences

This study represents phylogenetic analyses of two woody polygonaceous genera Calligonum and Pteropyrum using both chloroplast fragment (trnL-F) and the nuclear ribosomal internal transcribed spacer (nrDNA ITS) sequence data. All inferred phylogenies using parsimony and Bayesian methods showed that Calligonum and Pteropyrum are both monophyletic and closely related taxa. They have no affinity w...

Chemical and genetic diversity among some wild stands of Calligonum polygonoides (Polygonaceae) from the Thar Desert of Rajasthan.

The arid Western Rajasthan, where the Thar Desert of India is immersed, is mostly covered by sand dunes, a common landscape. The region has confronted with fragilities of natural resources, low, erratic and ill-distributed rainfall, and is covered up with many perennial hardy shrubs. Calligonumpolygonoides, the most common perennial shrub, is widely present in some localities of this Thar Deser...
