Evaluation of Genetic Variation and Simultaneous Selection for Seed Forage Yield in Selected Genotypes Dactylis glomerata Bromus inermis
خشکی تأثیر زیادی بر خصوصیات فیزیولوژیکی و مرفولوژیکی گیاهان میگذارد. تنش خشکی رابطه مستقیمی با خصوصیات جوانهزنی ازجمله درصد جوانهزنی، طول گیاهچه، نسبت ریشهچه به ساقهچه، وزن گیاهچه، نسبت وزن خشک به وزن تر گیاهچه و شاخص بنیه بذر دارد. در این تحقیق تأثیر تنش خشکی بر این خصوصیات در چهار ژنوتیپ از گونه bromus inermis شامل ژنوتیپهای (البرز 303، مازندران 3151، فیروزکوه 3966 و اصفهان 200060) در م...
Cells of the terrestrial plant species bromegrass (Bromus inermis L.) are not naturally adapted to withstand the hydrostatic pressures encountered in aquatic environments. However, after treatment with the natural plant growth hormone abscisic acid (75 micromolar), bromegrass cells survived a hydrostatic pressure of 101.3 megapascals, approximating the limits of ocean depth (10,860 m). The incr...
Exogenous nitrogen (N) inputs greatly change the emission and uptake of carbon dioxide (CO2) methane (CH4) from temperate grassland soils, thereby affecting (C) budget regional terrestrial ecosystems. Relevant research focused on natural grassland, but effects N fertilization C exchange fluxes different forage soils driving mechanisms were poorly understood. Here, a three-year addition experime...
Background: Weedy non-native species have long been predicted to be more phenotypically plastic than native species. Question: Are weedy non-native species more plastic than natives? Organisms: Fourteen perennial plant species: Acer platanoides, Acer saccharum, Bromus inermis, Bromus latiglumis, Celastrus orbiculatus, Celastrus scandens, Elymus repens, Elymus trachycaulus, Plantago major, Plant...
Karyotype and C-Banding Patterns of Mitotic Chromosomes in Diploid Bromegrass (Bromus riparius Rehm)
nomic relationships among species (Vosa, 1975; Cai and Chinnappa, 1987; Fominaya et al., 1988; Gill and Sears, Previous cytogenetic studies of the genus Bromus L. were limited 1988; Tayyar et al., 1994; Falistocco et al., 1995). The to chromosome counts and construction of karyotypes on the basis of Feulgen staining. Since the chromosomes of Bromus are similar in C-banding procedure has not bee...
