Phytophthora kernoviae oospore maturity, germination, and infection.
Limited information is known on the basic biology of the recently described Phytophthora kernoviae that produces homothallic oospores. In this study, different P. kernoviae isolates were used to investigate oospore maturity, germination, and infection. All isolates produced oospores in V8 broth at 20°C in the dark by 6d. Oospores also formed at 10 and 15°C, but did not form at 25 and 28°C. Cont...
متن کاملteraction effects of Allium spp . residues , concentrations d soil temperature on seed germination of four weedy ant species san
Soil in laboratory microcosm experiments was amended with dried and milled crop residue of onion (Allium cepa L. cv. Mission) or garlic (A. sativa L. cv. California Early). The amend ments, along with the additional factors of amendment concentration (0, 1 or 3% (w/w)) an soil temperature (23 or 39 8C), were evaluated with respect to germination of seeds of th weedy annual plants Echinochloa cr...
متن کاملDecomposition of Fresh and Anaerobically Digested Plant Biomass in Soil
Using water hyacinth [Eichhornia crassipes (Mart.) Solms) for wastewater renovation produces biomass that must be disposed of. This biomass may be anaerobically digested to produce CH4 or added to soil directly as an amendment. In this study, fresh and anaerobically digested water hyacinth biomass, with either low or high N tissue content, were added to soil to evaluate C and N mineralization c...
متن کاملRadioactivity level of soil around a coal-fired thermal power plant of northwest China
Background: The activity concentrations of natural radionuclides in soil around a coal-fired thermal power plant of northwest China were investigated for assessing the radioactivity level. Materials and Methods: Soil samples were collected around the coal-fired thermal power plant and their radioactivity levels were determined using gamma ray spectrometry. Radiation hazards were assessed by rad...
متن کاملAggregate Size Distribution Indices Influenced by Different Types/Managements of Plant Residues under Field Conditions
1- INTRODUCTION Nowadays, environmental aspects of soil erosion are specifically considered by researchers. In this regard, secondary (aggregate) particle size distribution (SPSD) is so important in different issues such as nutrient loss, pollutant transport and carbon cycle. Aggregate size distribution is known as the representative of soil structure, which is by itself regarded as a dynami...
