Enzyme affinity to cell types in wheat straw (Triticum aestivum L.) before and after hydrothermal pretreatment

Under greenhouse conditions, incorporating ground straw in the soil at rates between 2,240 and 8,970 kg/ha reduced the emergence of alfalfa (Medicago media Pers. cv. Beaver) significantly (P < 0.05) and bromegrass (Bromus inermis Leyss cv. Magna) slightly, but had no effect on barley (Hordeum vulgare L. cv. Conquest). Rape (Brassica napus L. cv. Target and B. campestris L. cv. Echo) straws were more damaging than wheat (Triticum aestivum L. cv. Manitou) straw. Symptoms of severe nitrogen deficiency appeared early in the growth of barley where straw had been added to the soil. The effect on tillering varied. In one experiment tillers were smaller, in one tillers were larger; but in both, total leaf area produced was much less where 8,970 kg/ha of straw had been added to the soil. Bromegrass showed the same effects but to a lesser degree, probably because of slower growth requiring a smaller supply of nitrogen. Alfalfa growth was apparently unaffected. There was no evidence that the straw of either rapeseed species was more deleterious than wheat straw to crop growth after emergence. It is concluded that straw incorporated in soil affected barley and bromegrass growth by reducing the availability of nitrogen.

Electromagnetic Radiations

The research work is devoted to researching the comparative influence of electromagnetic radiations with wavelengths on various physiological and morphological parameters of four common wheat Triticum aestivum L. cultivars from Kazakhstan and Egypt. The comprehensive studies concerning various Functional mechanisms of living organisms under the action of electromagnetic radiations is a problem of special priority in biophysics and photobiology, revealing the general and specific plant resistance features to a given radiation source. These are of special importance when electromagnetic irradiations are carried out using various wavelengths, expositions and power intensities. The reactivity responses of living organisms to the action of various physical radiations usually take a part both metabolically and anatomo-morphologically, that is directed mainly to maintaining homeostasis. The purpose was based to reveal the morphological and physiological indicators of seeds and plants of four common wheat Triticum aestivum L. in a comparative aspect before and after the influence of electromagnetic radiations with wavelengths of 400.0 - 800.0 nm. The specific seed reactions feature of Triticum aestivum L have been established after the influence of electromagnetic radiations applying expositions and wavelengths.

Abstract The objective of this study was to study the seed quality aspects of wheat (Triticum aestivum L.) and the extent of weed seed contamination present in wheat seeds produced in different regions of Iran. Four districts (cities), each including 12 fields (six certified seed fields and six farm-saved seed fields), were selected in each regions (provinces). One kilogram of the wheat seed sample was collected from each field for analysis in the laboratory. Wheat seeding was commonly done by farm-saved seed sourced from within the farm due to the high costs of certified seeds purchased from outside sources, followed by the low seed quality. The use of a farm-saved seed resulted in a higher germination rate and a lower mean time to germination compared with another system. The more positive temperatures experienced by mother plants could decrease the number of normal seedling and seedling length vigor index. Generally there was virtually no difference about physiological quality between certified seed and farm-saved seed sector that is related to lower quality of certified seed. The certified produced seeds had the lower number of weed seed, species and genus before and after cleaning. The highest seed purity and 1000 seed weight was obtained from the certified seed production system. The need for cleaning the farm-saved seed samples before sowing is one of the important findings of this survey.
