| unmanned aerial vehicle to estimate nitrogen status of turfgrasses. | spectral reflectance data originating from unmanned aerial vehicle (uav) imagery is a valuable tool to monitor plant nutrition, reduce nitrogen (n) application to real needs, thus producing both economic and environmental benefits. the objectives of the trial were i) to compare the spectral reflectance of 3 turfgrasses acquired via uav and by a ground-based instrument; ii) to test the sensitivity of the 2 data acquisition sources in detecting induced variation in n levels. n application gradient ... | 2016 | 27341674 |
| curvularia malina sp. nov. incites a new disease of warm-season turfgrasses in the southeastern united states. | a novel species of curvularia was identified as a foliar pathogen of cynodon dactylon (bermudagrass) and zoysia matrella (zoysiagrass), two important warm-season turfgrasses in the southeastern united states. field symptoms were conspicuous chocolate brown to black spots in turf of both species on golf course putting greens and fairways. leaves of plants within these spots exhibited prominent, black eyespot lesions from which a darkly pigmented fungus was consistently isolated. the fungus produc ... | 2016 | 27549619 |
| isolation, characterization and mapping of simple sequence repeat markers in zoysiagrass (zoysia spp.). | the genus zoysia consists of 16 species that are naturally distributed on sea coasts and grasslands around the pacific. of these, zoysia japonica, zoysia matrella, and zoysia tenuifolia are grown extensively as turfgrasses, and z. japonica is also used as forage grass in japan and other countries in east asia. to develop simple sequence repeat (ssr) markers for zoysiagrass (zoysia spp.), we used four ssr-enriched genomic libraries to isolate 1,163 unique ssr clones. all four libraries contained ... | 2005 | 16235048 |
| physiological and growth responses of six turfgrass species relative to salinity tolerance. | the demand for salinity-tolerant turfgrasses is increasing due to augmented use of effluent or low-quality water (sea water) for turf irrigation and the growing turfgrass industry in coastal areas. experimental plants, grown in plastic pots filled with a mixture of river sand and kosas(r) peat (9 : 1), were irrigated with sea water at different dilutions imparting salinity levels of 0, 8, 16, 24, 32, 40, or 48 ds m⁻¹. salinity tolerance was evaluated on the basis of leaf firing, shoot and root g ... | 2012 | 22666166 |
| reproduction of meloidogyne marylandi and m. incognita on several poaceae. | the susceptibility of 22 plant species to meloidogyne marylandi and m. incognita was examined in three greenhouse experiments. inoculum of m. marylandi was eggs from cultures maintained on zoysia matrella "cavalier" or cynodon dactylon x c. trasvaalensis "tifdwarf". inoculum of m. incognita was eggs from cultures maintained on solanum lycopersicum 'rutgers'. in each host test the inoculum density was 2,000 nematode eggs/pot. none of the three dicot species tested (gossypium hirsutum, arachis hyp ... | 2009 | 22661770 |
| systematic mining of salt-tolerant genes in halophyte-zoysia matrella through cdna expression library screening. | though a large number of salt-tolerant genes were identified from glycophyte in previous study, genes involved in salt-tolerance of halophyte were scarcely studied. in this report, an important halophyte turfgrass, zoysia matrella, was used for systematic excavation of salt-tolerant genes using full-length cdna expression library in yeast. adopting the gateway-compatible vector system, a high quality entry library was constructed, containing 3 × 10(6) clones with an average inserted fragments le ... | 2015 | 25689412 |
| heterologous expression of the halophyte zoysia matrella h⁺-pyrophosphatase gene improved salt tolerance in arabidopsis thaliana. | a number of vacuolar h(+)-pyrophosphatase (vp) family genes play important roles in plant growth under salt stress condition. despite their biological importance in plant salt-stress regulation, there is no report about vp in the halophytic turfgrass zoysia matrella. here, we isolated zmvp1, a type i vp homologues gene encoding 768 amino acids by using the degenerated pcr and race pcr methods from zoysia matrella. the expression level of zmvp1 was significantly induced by salinity, drought and c ... | 2015 | 25874657 |
