Carrot purple leaf disease was first reported in 2006 in the state of Washington and was associated with Spiroplasma citri. The disease also was reported in California in 2008. The objectives of this work were to fulfill Koch's postulates and to determine 1) whether the beet leafhopper, Circulifer tenellus (Baker) (Hemiptera: Cicadellidae), transmits carrot [Daucus carota L. subsp. Sativus (Hof...

Carotenoids are synthesized in prokaryotic and eukaryotic organisms. In plants and algae, these lipophilic molecules possess antioxidant properties acting as reactive oxygen species scavengers and exert functional roles in hormone synthesis, photosynthesis, photomorphogenesis and in photoprotection. During the past decade almost all carotenogenic genes have been identified as a result of molecu...

Brassica rapa displays enormous morphological diversity, with leafy vegetables, turnips and oil crops. Turnips (Brassica rapa subsp. rapa) represent one of the morphotypes, which form tubers and can be used to study the genetics underlying storage organ formation. In the present study we investigated several characteristics of an extensive turnip collection comprising 56 accessions from both As...

The article presents experimental data on the content of dietary fiber in confectionery industry products: raw materials for production products, chocolate, cookies, marshmallow, marmalade, candy, halva, iris. We investigated 30 samples materials, 10 kinds 9 different 20 candies and marshmallows marmalade. Of particular interest were non-traditional this industry, such as boiled carrots, zucchi...

UNLABELLED TURNIP comprises a suite of Perl scripts and modules that facilitates the resolution of microheterogeneity within hard-to-assemble repetitive DNA sequences. TURNIP was originally developed for the Saccharomyces Genome Resequencing Project (SGRP) within which the ribosomal DNA (rDNA) of 36 strains of S.cerevisiae were analysed to investigate the occurrence of potential polymorphisms. ...

ABSTRACT The objective of this work was to compare three methods estimating the optimal plot size evaluate fresh matter in black oat (Avena strigosa Schreb), common vetch (Vicia sativa L.) and forage turnip (Raphanus sativus intercropping. Six uniformity trials with oat, intercropping were carried out. Three evaluated at 84 days after sowing other 119 sowing. 216 basic experimental units (36 pe...

Streptomycin enhances the synthesis of anthocyanins and inhibits the synthesis of chlorophylls and the development of chloroplasts in dark-grown seedlings of cabbage (Brassica oleracea), mustard (Sinapis alba), tomato (Lycopersicon esculentum), and turnip (Brassica rapa) exposed to prolonged periods of irradiation in various spectral regions. These results suggest that the contribution of photo...

Heavy metal (HM) pollution is a global environmental problem that threatens ecosystem and human health. Cadmium (Cd) pollution is the most prominent HM pollution type because of its high toxicity, strong migration, and the large polluted area globally. Phytoremediation of contaminated soil is frequently practiced because of its cost-effectiveness and operability and because it has no associated...

Winter oilseed rape was cultivated in monoculture or in combination with turnip rape as trap crop sown in trap strip. Preventative microbiological treatments for diseases control in winter oilseed rape were tested using Trichoderma asperellum and product based on effective microorganisms. Microorganisms were effective to protect of oilseed rape and allowed to obtain higher yield comparing to un...
