Control of Seed Coat Thickness and Permeability in Soybean

Seed Coat Soybean Peroxidase: Extraction and Biocatalytic Properties Determination

Structure and Chemical Composition of Wild Soybean Seed Coat Related to Its Permeability

Four wild and two cultivated soybeans were examined for the water imbibition and relationships with seed coat structure, histochemical and epicatechin content using light, fluorescence, electron microscope, and HPLC technique. Cultivated cultivars, Pungsan and Chungja showed the highest water permeability, while the wild soybean lines, YWS16 and YWS136 showed moderate, and YWS1420 and YWS1459 d...

Suppressive mechanism of seed coat pigmentation in yellow soybean

In soybean seeds, numerous variations in colors and pigmentation patterns exist, most of which are observed in the seed coat. Patterns of seed coat pigmentation are determined by four alleles (I, i(i), i(k) and i) of the classically defined I locus, which controls the spatial distribution of anthocyanins and proanthocyanidins in the seed coat. Most commercial soybean cultivars produce yellow se...

Oyxgen and temperature effects on soybean seed coat respiration rates.

Soybean (Glycine max (L.) Merr) seed coat respiration rates in response to changing O(2) concentration and temperature were examined experimentally and with a mathematical analysis. The experimental observations showed seed coat respiration rates were sensitive to O(2) concentration below 0.25 micromole O(2) cm(-3). There was a steady decline in respiration rates from the saturating O(2) concen...

Soybean Seed Coat and Cotyledon Crack Detection by Image Processing

A computer vision system was used to evaluate seed coat and cotyledon cracks in soybeans. White light in the front-lighting mode with a black background for the soybeans was the best condition for acquiring video images of soybeans suitable for subsequent processing. Image processing algorithms were developed using the software supplied with the vision system computer. Crack detection was most ...
