A simple autoradiographic technique for studying diffusion of water into seeds.

چکیده
Visual observations on rates and modes of water penetration into black bean seeds and into wheat and sorghum kernels during conditioning were accomplished by an autoradiographic procedure that eliminates a freezing microtome and liquid and stripping film emulsions. Seeds soaked in tritiated H(2)O were hand sectioned before freeze-quenching in liquid N(2) and subsequent block autoradiography on nuclear medicine film.

Studying Effect of Water Quality Parameters on Coagulation Efficiency by Moringa Oleifera Seeds
The purpose of this study is to investigate the performance and efficiency of Moringa seeds from different sources on turbidity. A protein analysis test was done for each source; then two different methods of extraction were compared to examine the coagulation activity for the Moringa's active ingredient. The results of sodium chloride (NaCI) extraction in comparison to distilled water extracti...
متن کاملNumerical Investigation of the Effect of Gas Diffusion Layer with Semicircular Prominences on Polymer Exchange Membrane Fuel Cell Performance and Species Distribution
A three-dimensional computational fluid dynamics model of a proton exchange membrane fuel cell (PEMFC) with both gas distribution flow channels and Membrane Electrode Assembly (MEA) is developed. A set of conservation equation is numerically solved by developing a CFD code based on the finite volume technique and SIMPLE algorithm. In this research, some parameters like oxygen consumption, water...
متن کاملA Simple Method for Determining Aphelenchoides besseyi Infestation Level of Oryza sativa Seeds.
A simple extraction method was developed for obtaining the white tip nematode, Aphelenchoides besseyi Christie, from single seeds of rice, Oryza sativa. The method was as follows: Individual rice seeds were split longitudinally and then transferred into single pipet tips. Tips containing a split seed were then singly placed upright in glass vials with water to extract the nematodes. This method...

Citrus genus is known as one of the world's major economic agricultural products. In the current research, a method is reported for artificial seed production technology by shoot tips in Citrus sinensis.var. Thamson navel. Alginate is one of the most efficient gelling agents in the production of capsule coating in artificial seeding technique. In the current research, impact of different consti...
متن کاملInvestigations into seed dormancy in Grevillea linearifolia, G. buxifolia and G. sericea: anatomy and histochemistry of the seed coat.
BACKGROUND AND AIMS Seeds of east Australian Grevillea species generally recruit post-fire; previous work showed that the seed coat was the controller of dormancy in Grevillea linearifolia. Former studies on seed development in Grevillea have concentrated on embryology, with little information that would allow testing of hypotheses about the breaking of dormancy by fire-related cues. Our aim wa...
