A macaúba (Acrocomia aculeata) é uma palmeira oleaginosa e o extrativismo de seus frutos é de grande importância socioeconômica para os pequenos produtores rurais. O objetivo deste trabalho foi avaliar a variabilidade genética e obter informações sobre o controle genético de características morfológicas relacionadas ao crescimento e vigor da macaúba. Foram coletadas 51 progênies em Minas Gerais e São Paulo, as quais são integrantes do banco ativo de germoplasma da Universidade Federal de Viçosa. Doze meses após o plantio, essas progênies foram avaliadas quanto ao crescimento da planta (cm) e número de folhas emitidas. Estas características apresentaram grande variabilidade entre as progênies. As estimativas dos coeficientes de herdabilidade foram de 87% e...

The production of compact plants, which are slightly lacking in vigor and as productive as conventionally sized plants, is a trend in fruit growing. The objective of this study was to evaluate the vegetative performance and fruit quality of Gulfblaze and Reubennel plums intergrafted into two peach genotypes (UFV 186 and UFV 286). The experiment was arranged in a randomized block design using a 3x2 factorial arrangement (interstocks x cultivar) with four replications and one plant per plot. The non-intergrafted treatment was considered the control. Ten fruits were collected per plot for physical and chemical analyses. The evaluations were performed in the years 2014 and 2015. The interstock UFV 286 produced Gulfblaze trees with lower height in the two years...

Seed dormancy is an important adaptive mechanism in many species and is generally lost during plant domestication because of selection that occurs through the collection and planting of seeds. We compared germination and seedling emergence in selfed and open-pollinated progenies obtained from eight passion fruit vines (genotypes). Self-pollination was performed at the button stage to overcome self-incompatibility. The experiment was a randomized block design in a factorial scheme (2 x 8; type of progeny x genotypes) with four replicates and 50 seeds per experimental unit. At 14, 21 and 28 days after sowing, the germination percentage and the emergence speed index were analyzed. The total length of seedlings (cm), shoot length (cm), radicle length (cm) and...
