Abstract With the aim of developing an efficient plant regeneration protocol, leaflet explants of three accessions of Arachis villosa Benth. (S2866, S2867 and L97) were cultured on basic Murashige and Skoog medium supplemented with different combinations of plant growth regulators: α-naphthalenacetic acid, indole-3-butyric acid, 6-benzylaminopurine, kinetin and thidiazuron. The accession L97 was the only one able to differentiate buds through indirect organogenesis. The most suitable combination for bud regeneration was the basic medium added with 13.62 μM thidiazuron and 4.44 μM 6-benzylaminopurine. These results show the important role of the genotype in morphogenetic responses and the organogenetic effect of thidiazuron in… More >

Abstract Ango is the main species of fruit in the state of Campeche, Mexico, due to the economic benefits generated because of its production and marketing. Among the biotic problems that affect this crop in the region are weeds, which involve a heavy economic investment for their management. Under this scenario, it is important the development of ecological weed studies to generate information that help us to design strategies for managing the problem. During January to June 2010 a floristic study was developed on the population of weeds that compete with mango in the locations of Cayal and Castamay, at the… More >

Abstract The aim of the present review was to analyze and identify the problems associated with the Production System and Chain Value of Oregano in the area of Traslasierra Valley, province of Córdoba. Traditional ecotypes, such as Criollo, Chileno II and Compacto, are cultivated in the region, as well as new ecotypes such as “Serrano Cordobés”, “Flor Rosa” and “Rosa Fuerte”. The Traslasierra Valley of Córdoba is a very suitable area for the production and for increasing the production of oregano. However, the agricultural management of the different oregano ecotypes should be optimized. Ecophysiological studies conducted to date in the region… More >

Abstract We tested five Amaranthus genotypes (A. hypochondriacus 655, 653, 153-5-3, and Criollo Tlaxcala and A. cruentus genotype 33) at four population densities (31,250; 41,666; 62,500 and 125,000 plants/ha, during spring-summer (PV; July-December) 2000 and autumn-winter (OI) 2001 and 2002. Studies were conducted at the experimental station of the Agronomy Faculty of the Universidad Autónoma de Nuevo León, Mexico. A split plot experimental design on completely randomized blocks was used, with two replicates. The evaluated agronomic characteristics were grain yield (RG), dry matter yield (MS), plant height (AP), stem diameter (DT) and panicle length (LP). Crude protein (PC), ashes (C), acid… More >

Abstract Blackpoint incidence was assessed on grain from six durum wheat (Triticum durum Desf.) varieties grown during crop season 2004-05 at four sites, in the traditional durum wheat growing region of Argentina. Broad differences in grain discolouration were detected among sites and varieties, together with significant variety x site interactions. Among varieties, those with lower thousand grain weight and higher widthto- length ratio (proportionally shorter grains) showed less susceptibility to this disease than heavy/large grain varieties. Differences among sites in the levels of blackpoint incidence were also related to the physical attributes of grains revealing the strong influence of the environment… More >
