Giemsa C-banding in two polyploid, South American Hordeum species, H. tetraploidum and H. lechleri, and their aneuploid hybrids with H. vulgare

In Vitro Flower Production in Some Species of Hyoscyamus (H. pusillus L., H. arachnoideus Pojark, and H. niger L.)

Various plant organ segments including segments from roots (root tip, and root collar), stems, leaves, and also seeds of several Hyoscyamus species (i.e. H. pusillus, H. arachnoideus, annual and biennial H. niger from two distinct geographical regions) were cultured on MS media with various growth regulator combinations, to assess the ability of flower production. Statistical assessments showed...

Variation in salt tolerance of cultivated (hordeum vulgare L.)and wild (H. spontaneum C. koch)barley genotypes from iran

PREPARATION AND CHARACTERIZATION OF [Ni (MAP) ] ; H- MAP = 2- (METHYLAMINO) PYRIDINE H. Aghabozorg* and H. H. Monfared

We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...

Evaluation of Chemical Composition and In-vitro Biological Activities of Three Endemic Hypericum Species from Anatolia (H. thymbrifolium, H. spectabile and H. pseudolaeve)

In the present work we carried out a phytochemical and biological investigation on three endemic Hypericum species, i.e. Hypericum thymbrifolium, Hypericum spectabile and Hypericum pseudolaeve from Anatolia in order to discover new sources of natural compounds for the treatment of inflammatory and neurodegenerative disorders. HPLC-DAD analysis indicated that two naphthodianthrones (pseudohyperi...

قابلیت انتقال و تنوع ریزماهوارک‌های جو زراعی به گونه‌های واجد ژنوم H در جنس جو (Hordeum vulgare, H. bulbosum)

تعداد محدودی مارکرهای ریزماهوارک مناسب برای بررسی تنوع وراثتی گونه‌ی H. bulbosumوجود دارد. در این مطالعه قابلیت انتقال ریزماهوارک‌های جو زراعی به گونه‌ی H. bulbosumو تنوع پذیری آنها مورد بررسی قرار گرفته است. از 93 زوج پرایمر SSR آزمایش شده همگی در گونه‌ی H. vulgare(11 نمونه بذر) قطعاتی از DNA را تکثیر نمودند ولی تنها 46 زوج از آنها (61/51%) قابلیت انتقال به گونه H. bulbosum (5 نمونه بذر) با سط...
