Wheat is one of the most economically important cereals for Department Boyacá; however, cultivated area sees low yields, phytosanitary problems, and a lack genetic materials with desirable agronomic characteristics. The present study aimed to morphoagronomically characterize 49 accessions from FENALCE germplasm bank using morphological yield descriptors multivariate cluster analyses. variables ...

Different species of Triticum were grown during a greenhouse experiment, including T. monococcum L., T. dicoccum Schrank, T. durum Desf., T. spelta L. and T. aestivum cv. Vánek. The goal was to establish the influence of irradiance on the parameters of photosynthetic performance in relation to their ploidy. Photosynthetic rate (Pn), transpiration (E) and stomatal conductance (gs) were measured ...

Cereals represent the most important group of crops in the structure of plant production from the economic, agronomic and consumer point of view. Spelt wheat (Triticum spelta L.) is an ancient bread cereal related to wheat (Triticum aestivum L.) that has been cultivated for hundreds of years, and that is now being rediscovered in Europe and North America. Spelt is generating increasing interest...

Wheat (Triticum aestivum L. cv Sonalika) seedlings were grown in presence of K2Cr2O7 (10, 50 and 100 ppm) for 7 days and growth, total chlorophyll, activities of antioxidative enzymes like superoxide dismutase (SOD; EC 1.15.1.1), catalase (CAT; EC 1.11.1.6) and guaiacol peroxidase (POX; EC 1.11.1.7) and lipid peroxidation were determined in root and shoot tissues. Growth of the seedlings was si...

ARIEGATED seedcoat color was originally discovered in the variety Supreme (CI-8O26) which is reported to be a selection from Red Bobs (CI-6255) of hexaploid wheat, Triticum aestiuum L. The trait is characterized by a red and white variegated seedcoat and varying proportions of completely white-seeded tillers on plants with otherwise red o r variegated seeds, or red, white and variegated seeds a...

Lysates of protoplasts from the endosperm of developing grains of wheat (Triticum aestivum) were fractionated on density gradients of Nycodenz to give amyloplasts. Enzyme distribution on the gradients suggested that: (i) starch synthase and ADP-glucose pyrophosphorylase are confined to the amyloplasts; (ii) pyrophosphate: fructose-6-phosphate 1-phosphotransferase and UDP-glucose pyrophosphoryla...

Over 100 genes of resistance to rust fungi: Puccinia recondita f. sp. tritici, (47 Lr - leaf rust genes), P. striiformis (18 Yr - yellow rust genes) and P. graminis f. sp. tritici (41 Sr - stripe rust genes) have been identified in wheat (Triticum aestivum L.) and its wild relatives according to recent papers. Sixteen Lr resistance genes have been mapped using restriction fragments length polym...
