We examined concentrations of barium (Ba), cadmium (Cd}, copper (Cu), iron (Fe}, lead (Pb), and zinc (Zn) in buckwheat (Fagopyrum esculentum}, com (Zea mays}, giant ragweed (Ambrosia trifida), Pennsylvania smartweed (Polygonum pennsylvanicum }, and water hemp (Amaranthus rudis) seeds collected at the "3-Is" waterfowl impoundment at DePue Wildlife Management Area (DWMA}, DePue, Illinois, in the ...

This study was designed to determine the effect of exogenous spermidine (Spd) (30 μM) on white clover seed germination under water stress induced by polyethylene glycol 6000. Use of seed priming with Spd improved seed germination percentage, germination vigor, germination index, root viability and length, and shortened mean germination time under different water stress conditions. Seedling fres...

The high cost of treated water makes most people in the rural communities to resort to readily available water sources which are normally of low quality exposing them to waterborne diseases. The present study was carried out to confirm the effectiveness of seed powder extracted from mature-dried Moringa oleifera seeds which are commonly available in most rural communities. The main objective of...

Effects of soaking and cooking methods on physicochemical characteristics, nutrients and antinutrients in twenty soybean genotypes were studied. Batches of seeds were soaked for 18 h in distilled water, 1% citric acid and 2% sodium bicarbonate solutions at room temperature and then boiled in water. Raw soybean genotypes exhibited 36.5-43.2% protein, 20.7-22.2% oil, 2.58.3% total soluble sugars,...

The cell wall is a fundamental component in the response of plants to environmental changes. To directly assess the role of the cell wall we have increased the expression and activity of a cell wall associated peroxidase (TPX2), an enzyme involved in modifying cell wall architecture. Overexpression of TPX2 had no effect on wild-type development, but greatly increased the germination rate under ...

In searching for new sources of oil, protein and gelatin researchers have investigated many wild plants, but our research group took a different approach: We looked at insects as oil, protein and gelatin source for both nutritional and industrial applications. According to Sudanese indigenous knowledge, many insects have food and medicinal uses. We targeted two of these insects for our research...

Impatiens seeds treated with the ethylene biosynthetic precursor 1-aminocyclopropane-1-carboxylic acid (ACC) had reduced times to radicle protrusion and seedling emergence. Sixty hours after imbibition, 68% more seeds showed radicle protrusion on media containing 0.1 or 1.0 mM ACC compared to seeds germinated on water alone. Subsequently, ACC was effectively “loaded” into impatiens seeds using ...

Practical, effective methods that could be implemented in a food service establishment (restaurant or delicatessen) for the surface sanitization of cantaloupes were microbiologically evaluated. Cantaloupes (Cucumis melo L. var. reticulates) were immersed in an inoculum containing Salmonella enterica serovar Poona or Pantoea agglomerans at ca. 10(4) to 10(5) CFU/ml. An efficient method for the r...

Purpose. To evaluate the effect of pre-sowing soaking seeds on plant performance and economic efficiency watermelon melon growing drip irrigation in South Ukraine. Methods. Field, measuring, computational, comparative, mathematical/statistical methods, analysis efficiency. Results. Pre-sowing solutions silicon-containing fertilizers was shown to help obtain early full-bodied seedlings, increase...

It is commonly recognized that light-sensitive seeds require a period of imbibition before full promotion of germination by a light stimulus can be attained. Yet little work describes the nature of these preliminary events. Of the several major limitations that may be involved, clearly the rehydration (or activation) of phytochrome and the system with which it interacts are the chief ones to co...
