Agronomic performance and genetic dissimilarity among cherry tomato genotypes
Provedor de dados: 75
Autores: Maciel,Gabriel M; Finzi,Rafael R; Carvalho,Fábio J; Marquez,Guilherme R; Clemente,Andressa A.
ABSTRACT The genotypes evaluation in a germplasm bank is essential to determine their commercial or usefulness, as potential parents, in a breeding program. We aimed to detect the genetic diversity of 42 tomato genotypes of cherry type, belonging to the germplasm bank of the Federal University of Uberlândia and, also evaluate their behavior. The experiment was conducted in a greenhouse in randomized block design with 42 treatments and two replications. Ten quantitative traits of agronomic importance were evaluated. The genetic divergence was obtained by multivariate analysis, using the Mahalanobis distance with different clustering methods (UPGMA and Tocher). The hybrids performance was compared by Scott-Knott (p= 0.05) and Dunnett’s test (p= 0.05). UPGMA...

Influences of plant density and fruit thinning on watermelon hybrid production cultivated in different seasons
Provedor de dados: 75
Autores: Campos,Antônio Marcos D; Luz,José Magno Q; Santana,Denise G.; Marquez,Guilherme R.
ABSTRACT Brazilian watermelon productivity is not efficient when compared to the largest producer countries, due to abiotic and biotic factors. Some of the difficulties are because of a small number of studies on this crop in Brazil. The aim of this study was to evaluate the effects of plant density and fruit thinning on two commercial watermelon hybrids (Talisman and Youlie), using trials which were carried out in two different seasons (April - July and August - November). The experiment was conducted in Uberlândia-MG and consisted of two managements of fruit position (A-basal and B-distal) and four plant densities (3,000, 4,000, 5,000 and 6,000 plants/ha). In season 1, the distal management was the most productive in relation to all cultivation...
