Zbog kvalitete nutritivnoga sastava, pšenična se trava (Triticum aestivum L.) smatra funkcionalnom hranom te postaje sve popularnija kao dodatak svakodnevnoj prehrani ljudi. Cilj istraživanja bio je utvrditi utjecaj broja otkosa i sorte na ukupnu antioksidativnu aktivnost (DPPH), sadržaj kloroplastnih pigmenata, vitamina C, fenola flavonoida. U pokusu su ispitana dva genotipa pšenične trave, Tr...

Aim. The goal of this work was to study the effect drought in critical phase ontogenesis on growth and productivity breed winter wheat plants (Triticum aestivum L.). Methods. Wheat cultivars Darunok Podillya Podolyanka were grown under optimal nutrition well-water conditions until earing-flowering phase, after that experimental transferred regime for 8 days, water supply restored end vegetation...

Vacuoles isolated from pea (Pisum sativum), and wheat (Triticum aestivum) leaf protoplasts contained considerable activities of electrophoretically highly mobile exoamylases. Vacuoles from spinach (Spinacia oleracea) leaf and photoautotrophic Chenopodium rubrum suspension culture cell protoplasts were devoid of amylolytic activity. Endoamylase activity was in all cases associated primarily with...

A general method based on variation in repeated nucleotide sequences was developed for the identification of diploid species most closely related to a specific genome of a polyploid species. The utility of this method was demonstrated by showing that Triticum speltoides is the most closely related extant species to both the B and G genomes of tetraploid wheats.

Ethylene evolution from etiolated barley (Hordeum vulgare), wheat (Triticum aestivum), and rye (Secale cereale) seedlings during coleoptile growth followed a rhythmic pattern, with a period of about 16 h for barley and wheat and 12 h for rye seedlings. Leaf emergence disturbed the established rhythm of ethylene evolution.

Modern wheat (Triticum aestivum L.) is one of the most ozone (O(3))-sensitive crops. However, little is known about its genetic background of O(3) sensitivity, which is fundamental for breeding O(3)-resistant cultivars. Wild and cultivated species of winter wheat including donors of the A, B and D genomes of T. aestivum were exposed to 100 ppb O(3) or charcoal-filtered air in open top chambers ...

Puccinia triticina f. sp. tritici (Eriks.), the causal agent of leaf rust, causes substantial yield losses in wheat production. In wheat many major leaf rust resistance genes have been overcome by virulent races. In contrast, the prehaustorial resistance (phr) against wheat leaf rust detected in the diploid wheat Einkorn (Triticum monoccocum var. monococcum) accession PI272560 confers race-inde...

The English grain aphid, Sitobion avenae, is a major pest species of wheat crops; however, certain varieties may have stronger resistance to infestation than others. Here, we investigated 3 classical resistance mechanisms (antixenosis, antibiosis, and tolerance) by 14 wheat varieties/lines to S. avenae under laboratory and field conditions. Under laboratory conditions, alatae given the choice b...

The red coleoptile trait can help monocotyledonous plants withstand stresses, and key genes responsible for the trait have been isolated from Triticum aestivum, Triticum urartu, and Triticum monococcum, but no corresponding research has been reported for Aegilops tauschii. In this research, transcriptome analysis was performed to isolate the candidate gene controlling the white coleoptile trait...

Etiochloroplasts isolated from greening wheat (Triticum aestivum L. cv Norin 61) seedlings synthesized a membrane polypeptide of 15 kilodaltons. One-dimensional peptide mapping with Staphylococcus aureus V8 protease revealed that the 15 kilodaltons polypeptide is the subunit 5 of photosystem I reaction center complex.
