Normas DRIS para cupuaçuzeiro cultivado em monocultivo e em sistemas agroflorestais
Provedor de dados: 86
Autores: Dias,Jairo Rafael Machado; Perez,Daniel Vidal; Silva,Lucielio Manoel da; Lemos,Cleigiane de Oliveira; Wadt,Paulo Guilherme Salvador.
O objetivo deste trabalho foi avaliar a performance de normas DRIS específicas ou gerais no diagnóstico do estado nutricional do cupuaçuzeiro (Theobroma grandiflorum), na Amazônia Sul-Ocidental. Amostras foliares de cupuaçu foram coletadas de 153 pomares comerciais, com idade entre 5 e 18 anos, cultivados em monocultivo ou em sistemas agroflorestais. Foram geradas normas DRIS específicas para cada sistema de produção e normas gerais, obtidas para o conjunto da população monitorada. Na obtenção das normas, foi considerada a relação nutricional entre N, P, K, Ca, Mg, Fe, Cu, Zn e Mn. A maioria das médias das relações bivariadas entre nutrientes e dos diagnósticos produzidos pelas normas DRIS específicas não diferiu em relação aos produzidos com o uso da...

DRIS formulas for evaluation of nutritional status of cupuaçu trees
Provedor de dados: 90
Autores: Dias,Jairo Rafael Machado; Wadt,Paulo Guilherme Salvador; Perez,Daniel Vidal; Silva,Lucielio Manoel da; Lemos,Cleigiane de Oliveira.
DRIS, an Diagnosis and Recommendation Integrated System, is a tool to evaluate the nutritional status of plants. Different DRIS formulas have been proposed to improve the efficiency of the crop nutrition diagnoses. The objective of this study was to compare the nutritional diagnosis of the formulas of Beaufils (1973), of Jones (1981) and of Elwali and Gascho (1984), based on the degree of agreement in commercial orchards of Theobrama grandiflorum trees. Leaf samples of 5 to 18 year-old cupuaçu trees were collected from 153 commercial orchards in agroforestry and monoculture systems in the state of Rondonia, Brazil. Bivariate relationships between nutrition concentrations in healthy trees were used to calculate DRIS norms. DRIS indices were calculated based...

Crossing rate and distance in upland rice
Provedor de dados: 53
Autores: Silva,Edson Ferreira da; Silva,Lucielio Manoel da; Montalván,Ricardo.
Rice (Oryza sativa L.) is an autogamous species that shows natural crossing rates of up to 3%, where the variations are influenced by genotypes and environments. The present work aimed to evaluate the rates and distances of natural crossing between the upland rice cultivars Guarani and IAC 201. The study was done in the counties of Carpina and Recife, in the State of Pernambuco during the agricultural years of 2001 and 2002, respectively. The Guarani cultivar presents leaf pilosity conditioned by the dominant alleles HLHL and this character was used as a morphologic tracer. On the other hand, the IAC 201 cultivar does not show pilosity because it carries the recessive alleles (hlhl). The experiments were composed of four blocks, constituting of ten...
