The Buyeo Royal Tomb No. 1 is an ancient tomb built in the late 6th and early 7th century. four walls of main room have murals guardian deities, ceiling has lotus cloud patterns. This study assessed optimal growth conditions two fungal (Fusarium oxysporum, Mortierella sp.) bacterial (Bacillus cereus, Cupriavidus campinensis, Streptomyces avidinii, cirratus) strains isolated from 1, along with t...
Returns of an individual enterprise in the short term are usually measured through a gross margin budget, which is determined by subtracting factors such as the cost of weed control (both herbicide and non-herbicide) and other inputs (eg seed and fertiliser) from gross income (calculated as crop yield multiplied by grain price). Crop yield is directly influenced by weed density, which itself is...
laboratory experiments were performed to determine the effect of various scarification treatments at four temperature regimes on germination of licorice seeds . a randomized complete block design with four replications was used. germination counts were made every day for 2 weeks. at 50c, none of the chemically and mechanically scarified and non scarified seeds germinated. at 15, 25, and 350...
Grassland diversity can support sustainable intensification of grassland production through increased yields, reduced inputs and limited weed invasion. We report the effects of diversity on weed suppression from 3 years of a 31-site continental-scale field experiment.At each site, 15 grassland communities comprising four monocultures and 11 four-species mixtures based on a wide range of species...
Abstract Purpose In cold climates, glyphosate residues may linger in soils, with effects on plant–microbe interactions and, consequently, plant performance. Here, we explore the influence of endophytic microbiota (bacteria and fungi) performance perennial nitrogen-fixing weed Lupinus polyphyllus . Methods a common garden, grew plants from six populations L. glyphosate-treated or untreated contr...
The airborne fungal spore content in Havana, Cuba, collected by means a non-viable volumetric methodology, was studied from November 2010 - October 2011. The study, from a qualitative point of view, allowed the characterization of 29 genera and 5 fungal types, described following the Saccardo´s morphotypes, as well as their morphobiometrical characteristics. In the amerospores morphotype, the c...
Overgrowing (interaction) and dissolution of intact and milled hot particles by various micromycetes were studied under laboratory conditions. Hot particles used for the investigation originated from the Chernobyl accident release and atomic bomb testing sites. The micromycetes investigated were mitosporic fungi mainly isolated from the Chernobyl site and vicinity. Most of the fungal species an...
Weed control is one of the most important crop protection activities undertaken in both intensive and low-input farming systems. However, even under intensive systems, crop protection which is less dependent on pesticides may require that weeds be managed to obtain a balance between crop and non-crop vegetation to encourage an increase in natural enemies of crop pests. In the low-input farming ...
Predicting the population dynamics of annual plants is a challenge due to their hidden seed banks in the field. However, such predictions are highly valuable for determining management strategies, specifically in agricultural landscapes. In agroecosystems, most weed seeds survive during unfavourable seasons and persist for several years in the seed bank. This causes difficulties in making accur...
