Garlic (Allium sativum L.) is one of the oldest cultivated plants in world and belongs to family Amaryllidaceae. Purple blotch caused by Alternaria porri (Ellis) Ciferri such disease which causes a great deal loss for farmers. The best method manage purple adopt resistant genotypes cultivation, highly necessary areas with high incidence. In order identify sources, 37 were field screened under a...

Understanding what factors are the major influences on wine composition will assist in the successful management of grape composition in the vineyard and/or variables in the winery to produce wines with specific sensory attributes. A recently developed analytical method [headspace solid-phase microextraction comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry] was ...

A nondestructive fluorescence-based technique for evaluating Vitis vinifera L. grape maturity using a portable sensor (Multiplex) is presented. It provides indices of anthocyanins and chlorophyll in Cabernet Sauvignon, Merlot, and Sangiovese red grapes and of flavonols and chlorophyll in Vermentino white grapes. The good exponential relationship between the anthocyanin index and the actual anth...

to study inheritance of resistance to septoria tritici blotch in wheat, the generation mean analysis method was used. so six generations (p1, p2, f1, f2, bc1 and bc2) were planted under completely randomized design with three replications in greenhouse. seedlings were inoculated at the second-leaf stage with an isolate of septoria tritici and necrosis and picnidia density and area under disease...

Molecular markers were used for assessing genetic diversity in Finnish six-rowed barley and for mapping and tagging genes affecting traits important in barley breeding. Finnish six-rowed barley germplasm is narrow-based: twenty two released varieties are largely composed of only seven ancestors. The level of diversity in the RAPD markers has remained during barley breeding. Coancestry based on ...

Barley, Hordeum vulgare L., is the most important crop in Finland based on cultivated land area. Net blotch, a disease caused by Pyrenophora teres Drech., is the most damaging disease of barley in Finland but is also important in other barley cultivating areas. The pressure to improve the economics and efficiency of agriculture has increased the need for more efficient plant protection methods....

Fungicides continue to be essential for the effective control of plant diseases. The azoles class of fungicides has been the leading agents for the control of fungal pathogens of plants since their introduction in the mid 1970s. This class of fungicides is also called sterol demethylation inhibitors (DMIs) because they inhibit the formation of cytochrome P450 sterol 14 alpha-demethylase (450 14...

Abstract Breeding of multi-resistant varieties to reduce yield loss due disease damage and lodging, reduction input intensity are high importance for a more sustainable cereal production. The aim this study was evaluate (i) caused by diseases lodging (ii) impact soil fertility in variety trials grown under two intensities. Intensity 2 treated with 1 without fungicides growth regulators. We appl...

Retroculus acherontos is described from the Rio Tocantins basin, Brazil. It is distinguished from all congeners by the presence of a nuchal hump in large specimens, an irregular black blotch located on the middle of the anterior soft dorsal-fin rays, fewer pectoral-fin rays (15-16), a deeper body, a convex ventral profile, a more transversely convex ventral surface of the body, and by chest sca...
