Benzoxazinones 2,4-dihydroxy-7-methoxy-(2H)-1,4-benzoxazin-3(4H)-one (DIMBOA) and 2,4-dihydroxy-(2H)-1,4-benzoxazin-3(4H)-one (DIBOA) have been considered key compounds for understanding allelopathic phenomena in Gramineae crop plants such as corn (Zea mays L.), wheat (Triticum aestivum L.), and rye (Secale cereale L.). The degradation processes in the environment observed for these compounds, ...

the studies carried out over 2010-13 involved a static field experiment initiated in 1999 at brody research station of the poznan university of life science, poland. the soil tillage systems for winter wheat were compared on a soil classified as albic luvisols. the aim of experiments was to evaluate impact of ploughless soil tillage on some soil physical, chemical, biological properties and win...

the effects of drought stress and exogenous abscisic acid on the expression of ribulose-1, 5-bisphosphate carboxyiase/oxygenase activase (rubisco activase) were examined in wheat (triticum aestivuml.). in response to water stress and abscisic acid, both the levels of endogenous abscisic acid and rubiscoactivase increased in the leaves. immunoblot analysis showed that both drought stress and abs...

Aim. To investigate the functionality of transgene in seed generation (T2) genetically modified winter wheat plants (Triticum aestivum L.) terms productivity conditions normal and insufficient water supply. Methods. Determination yield structure protein content. Results. The indicators control T2 biotechnological under growing deficit are analyzed. quantitative composition before after osmotic ...

Tetrameric inhibitors of heterologous alpha-amylases have been characterized in allohexaploid wheat, Triticum aestivum (genomes AABBDD), as well as in Triticum turgidum (AABB) and Triticum tauschii (DD). Their subunits have been identified as the previously described CM proteins. Single oligomeric species were observed in T. Turgidum (subunits CM2, CM3A, and CM16) and in T. tauschii (CM1, CM3D,...

Effects of Nigella sativa Allelochemical Substances on Growth-Inhibiting Flixweed Compared With Wheat (Triticum aestivum)

Restriction map variation in two 5-6-kb chloroplast DNA regions of five diploid Aegilops species in the section Sitopsis and two wild tetraploid wheats, Triticum dicoccoides and Triticum araraticum, was investigated with a battery of four-cutter restriction enzymes. A single accession each of Triticum durum, Triticum timopheevi and Triticum aestivum was included as a reference. More than 250 re...
