Changes in Sugar Content in Winter Wheat during Overwintering

Predicting Grain Protein Content of Winter Wheat

The objective of this paper is to propose to use a new Improved Particle Filtering (IPF) based on minimizing Kullback-Leibler divergence for crop models' predictions. The performances of the method are compared with those of the conventional Particle Filtering (PF) at a complex crop model (AZODYN) to predict an important winter-wheat quality criterion, namely the grain protein content. Furtherm...

Effect of urea foliar feeding on grain protein content and quality in two winter wheat cultivars

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...

Rapid estimation of sugar release from winter wheat straw during bioethanol production using FTIR-photoacoustic spectroscopy

BACKGROUND Complexity and high cost are the main limitations for high-throughput screening methods for the estimation of the sugar release from plant materials during bioethanol production. In addition, it is important that we improve our understanding of the mechanisms by which different chemical components are affecting the degradability of plant material. In this study, Fourier transform inf...

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...
