Meiotic Studies in Some Species of Tribe Cichorieae (Asteraceae) from Western Himalayas

The present paper deals with meiotic studies in 15 species belonging to 6 genera of the tribe Cichorieae from various localities of Western Himalayas. The chromosome number has been reported for the first time in Hieracium crocatum (2n = 10) and Lactuca lessertiana (2n = 2x = 16). Further, intraspecific variability has been reported for the first time in H. umbellatum (2n = 2x = 10 and 2n = 6x ...

کاربرد مورفولوژی فندقه در رده بندی چند گونه از قاصدک (Asteraceae tribe Cichorieae) در ایران

میکرومورفولوژی هفده گونه متعلق به جنس قاصدک (تیره آفتابگردان) با استفاده از میکروسکوپ الکترونی مورد بررسی قرار گرفت. در این مطالعه دوازده صفت کمی و کیفی از قبیل طول، عرض و رنگ فندقه، نوع و اندازه تزئینات بدنه فندقه، طول منقار، طول و رنگ پاپوس بررسی شد. آنالیز خوشه­ای و آنالیز مولفه اصلی داده­ها نشان داد که میکرومورفولوژی فندقه در تفکیک گونه‌ها از یکدیگر نقش مهمی داشته در حالیکه جداسازی در سطح ب...

Phenolics from Rhagadiolus stellatus (Asteraceae, Cichorieae)

Rhagadiolus stellatus Gaertn., a Mediterranean member of the Cichorieae tribe of the Asteraceae family used as a food plant, was analyzed for its spectrum of phenolic compounds. Kaempferol 3-O-β-glucoside 1, kaempferol 3-O-β-rutinoside (nicotiflorin) 2, quercetin 3-O-β-glucoside 3, and luteolin 4 were isolated from the n-butanol layer of a methanolic extract of whole plants of Rh. stellatus of ...
