effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Correction: Dinosaur Footprints and Other Ichnofauna from the Cretaceous Kem Kem Beds of Morocco
We describe an extensive ichnofossil assemblage from the likely Cenomanian-age 'lower' and 'upper' units of the 'Kem Kem beds' in southeastern Morocco. In the lower unit, trace fossils include narrow vertical burrows in cross-bedded sandstones and borings in dinosaur bone, with the latter identified as the insect ichnotaxon Cubiculum ornatus. In the upper unit, several horizons preserve abundan...
متن کاملExceptionally diverse morphotypes and genomes of crenarchaeal hyperthermophilic viruses.
The remarkable diversity of the morphologies of viruses found in terrestrial hydrothermal environments with temperatures >80 degrees C is unprecedented for aquatic ecosystems. The best-studied viruses from these habitats have been assigned to novel viral families: Fuselloviridae, Lipothrixviridae and Rudiviridae. They all have double-stranded DNA genomes and infect hyperthermophilic crenarchaea...
متن کاملComponents of pollinator "quality": comparative analysis of a diverse insect assemblage
A total of 34 floral visitors of Lavandula latifolia (Labiatae) at a southern Spanish locality were examined from the perspective of their "quality" as pollinators. I considered frequency of pollen transfer, number of pollen grains deposited on the stigma, selection of floral sexual stage (flowers are markedly protandrous), and patterns of flight distance between flowers. Hymenoptera deposited ...
متن کاملIntra-Trackway Morphological Variations Due to Substrate Consistency: The El Frontal Dinosaur Tracksite (Lower Cretaceous, Spain)
An ichnological and sedimentological study of the El Frontal dinosaur tracksite (Early Cretaceous, Cameros basin, Soria, Spain) highlights the pronounced intra-trackway variation found in track morphologies of four theropod trackways. Photogrammetric 3D digital models revealed various and distinct intra-trackway morphotypes, which reflect changes in footprint parameters such as the pace length,...
