Ancient Wheat Species Can Extend Biodiversity of Cultivated Crops [PDF]

open access: yes, 2011
Wheat genetic resources may be grown in organic farming systems or in less favourable areas for bread wheat species. Characteristics of hulled wheat species (23 varieties of einkorn, emmer wheat, spelt wheat) were studied and evaluated within a two-year ...

Environmental assay on the effect of poultry manure application on soil organisms in agroecosystems [PDF]

open access: yes, 2012
This paper reports the effects produced on the organisms of the soil (plants, invertebrates and microorganisms), after the application of two types of poultry manure (sawdust and straw bed) on an agricultural land.

An integrated social and natural sciences case study for the reuse of organic wastes as soil amendments

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Reusing organic waste materials, such as animal manure, as soil amendments reduces water and fertiliser demand, contributing to achieving the Sustainable Development Goals. However, organic wastes may contain contaminants of emerging concern (CECs), posing potential ecosystem and human health risks. Despite the importance of this issue, there is a lack

Non-host volatiles do not affect host acceptance by alate virginoparae of Rhopalosiphum padi (Hemiptera: Aphididae) settled on the host plant surface

open access: yesEuropean Journal of Entomology, 2005
Using electrical penetration graphs to monitor aphid feeding, it was shown that volatiles of a non-host plant (alfalfa, Medicago sativa L.) did not disrupt the process of host acceptance by alate virginoparae of the birdcherry-oat aphid, Rhopalosiphum ...

Sources of nitrogen for winter wheat in organic cropping systems [PDF]

open access: yes, 2013
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure.

Comparative efficacy of seed biopriming and soil drenching with Bacillus altitudinis TM22 and Bacillus atrophaeus MCM61 on the suppression of Fusarium wilt of cotton

open access: yesPest Management Science, EarlyView.
Co‐application of Bacillus strains TM22 and MCM61 suppressed Fusarium wilt of cotton. Seed biopriming with Bacillus strains performed better than soil drenching. TM22 + MCM61 improved vegetative and physiological aspects in cotton plants. TM22 + MCM61 enhanced the activity of defense enzymes and defense gene expression.

Effects of Growth Temperatures on the Fatty Acid Composition of Isolated Chloroplasts From Two Species Differing in Heat Sensitivity [PDF]

open access: yes, 1985
Lipid analyses of chloroplasts isolated from wheat (Triticum aestivum L. cv. Arthur) and milo (Sorghum bicolor cv. Funk\u27s hybrid 522) suggest no major heat effect on lipid class distribution.

Quantitative trait loci conferring grain mineral nutrient concentrations in durum wheat 3 wild emmer wheat RIL population [PDF]

open access: yes, 2009
Mineral nutrient malnutrition, and particularly deficiency in zinc and iron, afflicts over 3 billion people worldwide. Wild emmer wheat, Triticum turgidum ssp. dicoccoides, genepool harbors a rich allelic repertoire for mineral nutrients in the grain.

A new method to measure EC50 reveals cultivar‐specific fungicide resistance and very high diversity within experimental field populations of Zymoseptoria tritici

open access: yesPest Management Science, EarlyView.
We isolated Zymoseptoria tritici strains from a diverse wheat field and quantified fungicide resistance using a novel plate assay. We found high diversity in fungicide sensitivity and host–fungicide–pathogen interactions. Abstract BACKGROUND Zymoseptoria tritici causes Septoria tritici blotch (STB), the most damaging wheat disease in Europe. In Europe,

Mapa molekularna pszenicy (Triticum aestivum L.)

open access: yesBiuletyn Instytutu Hodowli i Aklimatyzacji Roślin, 2007
Utworzono wstępną mapę molekularną pszenicy zwyczajnej wykorzystując populację podwojonych haploidów wyprowadzonych z kombinacji krzyżówkowej odmian Liwilla i Begra. Odmiany rodzicielskie i linie potomne genotypowano stosując markery SSR i DArT. W wyniku przepro-wadzonych analiz zidentyfikowano 269 polimorficznych markerów DArT.
