Caracterização fenotípica de populações e desenvolvimento inicial de plantas de Campomanesia adamantium (Cambess.) O. Berg, em Mato Grosso do Sul

Abstract

The aim of this work was to evaluate emergence and fruit biometry often populations of C. adamantium from Cerrado (sensu stricto) area, in Dourados-MS. The establishment of coordinates of every population was obtained as a function of phenotypic difference showed among them, distributed in an area of 32 ha, which is a remnant area of Cerrado of Santa Madalena Farm. Collect of fruits were done in the second period of fifteen days of December, 2009, fruitful period of the specie. For biometry study , a complete randomized experimental design was used, with ten treatments, which corresponded to populations and ten replications of ten fruits, which corresponded to experimental units. Germinative behavior study of seeds was carried out in green house conditions and use randomized block design, with four replications of sixteen seeds, as experimental unit, for every population. In biometry study of fruits and in germinative behavior of seeds, it was observed the presence of groups statistically different for every evaluated characteristic. Populations of Campomanesia adamantium, in native area, showed fruits with high phenotypic variability . In green house, seedlings by seed propagation showed a small proportion of phenotypic diversity . Considering characteristics of fruits and propagatives, populations 4, 9 and 10 are outstanding as the highest potential for genetic studies and for improvement.
