Differential responses of Phaseolus spp. against Black node disease (Boeremia noackiana)
نویسندگان
چکیده
Black node disease is one of the most limiting biotic stresses affecting bean production in Andean countries. The objective study was to evaluate degree resistance Boeremia noackiana against genotypes Phaseolus vulgaris, polyanthus, and their interspecific crosses using two evaluation methods (pathogenicity test greenhouse vitro) contribute generation knowledge towards use durable resistance. severity assessed a descriptive scale leaf detached method under in-vitro conditions. results confirmed isolate Ascochyta ASC 001 pathogenicity, allowing different be discriminated. A contrasting response for methodologies used estimate severity. Accession G35575 (P. polyanthus) resistant whereas NCB 226 vulgaris) susceptible. Regional cultivars Simijaca Cabrera, together with Cargamanto Blanco Bacata, showed fluctuations reaction from intermediate Resistance series, which can an alternative breeding programs common beans. percent area affected identified as variable that easily assessed, processing analysis digital images vitro avoided destructive sampling. This technique fast, useful, economical tool this type studies, it provides possibility accelerating selection

During this study, 192 one-day-old broiler chicks (Ross-380) in four groups with three replica...
متن کاملDifferential responses of two Iranian rice cultivars to arsenite toxicity
Arsenic (As) is a toxic metalloid which is usually found in rice fields as a contamination and has negative effects on the plant growth and reduces the crop yield. Similar to heavy metals, the deleterious effects of As may be due to, at least in part, the amount of absorbed As and disturbance of the plant water status. I...
