ABSTRACT

The corn-grass intercropping system began to be used in the dry season, as it provides increased straw production for the no-tillage system. However, corn and grass are plants demanding in nitrogen. The corn cultivated in the dry season is called out-of-season corn in Brazil. The objective of this study was to evaluate the productivity and nutrients concentrations of out-of-season corn and Congo-grass intercropped in the no-tillage system, as a function of the nitrogen rates applied in sidedressing. The treatments were four nitrogen rates, 0, 30, 60 and 90?kg?ha^?1. The experimental design was randomised complete blocks with four replicates. The experimental period corresponded to the harvests of 2015 and 2016. There were evaluated: corn grain yield, dry mass production and nutrient concentration in the shoots of the plants intercropped. The evaluations were carried out at the physiological maturity stage of the corn and at the time of desiccation of the grass. Nitrogen increased grain yield and dry mass production of the plants intercropped. Nitrogen maximised the magnesium concentration in out-of-season corn and the nitrogen, calcium, magnesium and sulphur concentrations in Congo grass. Excess nitrogen promoted reduction of the phosphorus in the Corn-Congo grass intercropping system in the dry season.  相似文献

Molecular and morphological characterization of Golestan (Iran) olive ecotypes provides evidence for the presence of promising genotypes   总被引：1，自引：1，他引：0

Unidentified olive plants naturally grow in the Golestan province of Iran, on different soils and under climates spanning from sub-temperate to desert conditions, represented by single trees or groups of few trees. We collected samples from representative sites and analyzed them by simple sequence repeat markers in order to determine their identity and their relationships to prominent Iranian and Mediterranean reference cultivars. Population structure analysis separated these ecotypes from Mediterranean and, surprisingly, from all Iranian cultivars, the parentage test excluded their direct contribution as candidate parents or offspring of cultivars, and they also showed a high level of admixture. Their differentiation from cultivated olives may be attributed to different factors: they could represent wild plants or could derive from natural dissemination of ancestral cultivated trees. Their survival up to now may be due to the fact that most of them are grown on sacred sites such as necropolis. Anyhow, the adaptation to strong environmental stresses, and their fruit size and oil content make the olive Golestan ecotypes a valuable source of genetic variation previously uncharacterized and currently threatened with extinction.  相似文献   

Is community-based forest management more effective than protected areas?: A comparison of land use/land cover change in two neighboring study areas of the Central Yucatan Peninsula,Mexico     

Edward A. Ellis  Luciana Porter-Bolland 《Forest Ecology and Management》2008

The importance of the role of local community forestry institutions towards forest conservation is exemplified through a comparison of two adjacent areas within the Central Yucatan Peninsular Region (CYPR) in which Land-Use Cover Change (LUCC) analyses were conducted. We also used logistic regression analyses to examine key environmental, socioeconomic and institutional drivers associated with deforestation. One of the areas, La Montaña (LM) at Hopelchen, Campeche, is part of the northern section and buffer zone of the Calakmul Biosphere Reserve (CBR) as well as part of the Mesoamerican Biological Corridor. LM is an agricultural forest frontier region economically dependent on productive activities. The other study, Zona Maya (ZM), found at the municipality of Felipe Carrillo Puerto in Quintana is characterized by having developed community-based forestry enterprises with world wide recognition. In addition, the major tourism industry in nearby Cancun and Riviera Maya provide an important source of off-farm labor and temporary migration. Results show contrasting annual deforestation rates among the two study areas, being greater in the Campeche site (0.7% from 2000 to 2005) compared to Quintana Roo (−0.002% from 2000 to 2004). Logistic regression results show that the occurrence of land clearing at LM is significantly related to demographic variables as well as soil-environment types and conservation status did not reveal to relate to LUCC processes at all. At Quintana Roo, despite twice the population density, population variables at large did not strongly correlate to forest clearing. Rather forest conservation or maintenance was shown to be influenced by local community forestry institutions and a landscape zoning provided by larger management goals from the part of the communities. Greater availability of wage labor for the prominent tourism economy may also reflect a lesser dependence on agriculture and contribute to the much lower deforestation rate. Nonetheless, results show that community forest management can play an effective role in forest conservation. We argue for a regional land use management approach as a conservation strategy in which local inhabitants are considered key actors.  相似文献

Investigation of Genomic Variability of Xanthomonas Arboricola Pv. juglandis by AFLP Analysis     

Stefania Loreti  Angela Gallelli  Alessandra Belisario  Eric Wajnberg  Luciana Corazza 《European journal of plant pathology / European Foundation for Plant Pathology》2001,107(6):583-591

Xanthomonas arboricola pv. juglandis is the causal agent of walnut blight, one of the most important and widespread diseases of Persian (English) walnut (Juglans regiaL.), causing severe damage to leaves, twigs and nuts. To investigate the genomic variability of X. arboricolapv. juglandis, 66 isolates obtained from different countries (England, France, Italy, The Netherlands, Romania, Spain, USA, and New Zealand) were analysed using the Amplified Fragment Length Polymorphism (AFLP) technique. EcoRI and MseI were used as restriction endonucleases. Primers with a core sequence including endonuclease recognition sites and a 3^prime-terminal cytosine selective base for MseI primer, or no selective base for EcoRI primer, were used. Data were analysed by means of a multiple correspondence analysis. A total of 76 amplified polymorphic DNA fragments were used to compute relationships among isolates. The AFLP profiles of X. arboricola pv. juglandis isolates appeared to be reliably distinguishable from X. arboricola pv. pruni and X. arboricola pv. corylina, and from other Xanthomonas species, i.e. X. campestris pv. campestris, X. fragariae, X. hortorum, X. axonopodis pv. vesicatoria. Though this pathogen is associated with one single host genus, a high level of genomic diversity was found. This diversity might be partly explained by the geographic origin. Nevertheless, isolates with different patterns were collected within one country, and similar molecular patterns were found in isolates collected at different sites. However, genetic diversity might be influenced by exchanging vegetative material from different countries. Mixing of X. arboricola pv. juglandis isolates might have partly concealed the influence of the geographic location from which the bacteria were isolated.  相似文献
