Near-Infrared Hyperspectral Imaging of Fusarium-Damaged Oats (Avena sativa L.)

Subcellular Localization of Proteases in Developing Leaves of Oats (Avena sativa L.).

The distribution and subcellular localization of the two major proteases present in oat (Avena sativa L. cv Victory) leaves was investigated. Both the acidic protease, active at pH 4.5, and the neutral protease, active at pH 7.5, are soluble enzymes; a few percent of the enzyme activity was ionically bound or loosely associated with organellar structures sedimenting at 1000g. On the average, 16...

Identification of Oats (Avena sativa L.) Cultivars by Seed and Seedling Protein Electrophoresis

Soluble proteins were extracted from seed and seedlings of eleven oats cultivars to analyze the protein profile through SDS PAGE method. In seed protein electrophoresis totally 14 bands were observed, in these six bands were common to all cultivars. Based on the seed protein banding pattern two of these cultivars were differentiated easily. The unique band at Rf value 0.151 was common for all c...

Chiasma frequency, distribution and terminalization in hexaploid oats (Avena sativa L.)

Chiasma counting has been regarded as the most straightforward method of scoring the total number of crossing-over events in the genome. In organisms in which genetic analysis is difficult or impossible to perform, it is a good estimator of the level of genetic recombination. In this paper we evaluated the chiasma frequency and distribution at diakinesis of twelve Brazilian oat varieties (Avena...

Detection of Sprouted and Midge-damaged Wheat Kernels Using Near-infrared Hyperspectral Imaging

Sprout damage which results in poor bread making quality due to enzymatic activity of alpha-amylase is one of the important grading factors of wheat in Canada. The potential of near-infrared (NIR) hyperspectral imaging was investigated to detect sprouting of wheat kernels. Artificially sprouted, midge-damaged and healthy wheat kernels were scanned using NIR hyperspectral imaging system in the r...
