Changes of Quality of Winter Wheat During Maturing

Stability and predictability of baking quality of winter wheat

Baking quality of 11 winter wheat varieties was studied at the Jõgeva Plant Breeding Institute during 5 years (2005–2009). Protein content, farinograph absorption, dough stability time and loaf volume were examined in this study. The varieties were divided into clusters according to the average value of quality characteristics and coefficient of variation. Ada, Tarso, Portal, Ramiro had high pr...

Changes in Membrane Permeability of Winter Wheat Cells

Nuclear etic resoaace (NMR) relaxation times were studied in acclhnated and nonacclmated Kharkov winter wheat (Tritlum sestlvwm L.) crowns and acclimated cel aggregates to determine if membrane permeability was altered by freezing. The NMR water signal decay consisted of two exponental c ets: a short one arising from extracellular water, and a long one arising from intracelular water. A slow fr...

Coating seeds with endophytic fungi enhances growth, nutrient uptake, yield and grain quality of winter wheat

The aim of this study was to assess whether seed coating with microbialconsortium based on the arbuscular mycorrhizal (AM) fungus Glomus intraradicesBEG72, Glomus mossae and Trichoderma atroviride MUCL 45632 could improveseedling establishment, yield and grain quality (protein content and mineralcomposition) of wheat (Triticum durum Desf.). As a first step, a laboratoryexperiment was conducted ...

Adaptive Changes in ATPase Activity in the Cells of Winter Wheat Seedlings during Cold Hardening.

A cytochemical study of ATPase activity in the cells of cold hardened and nonhardened winter wheat (Triticum aestivum L. cv. Nongke No. 1) seedlings was carried out by electron microscopic observation of lead phosphate precipitation. ATPase activity associated with various cellular organelles was altered during cold hardening. (a) At 22 degrees C, high plasmalemma ATPase activity was observed i...
