Rhizobium radiobacter is a significant causal agent that ranks among the top ten bacteria of molecular plant pathology in world, has largest range hosts pathogenic bacteria, and limits production leads to economic losses agriculture. The distinctive feature from other Ti plasmid, extrachromosomal structure present all virulent types. In this study, virulence five R. isolates (1A, 1B, 2A, 2B RK ...

The use of micropropagated trees has been widely extended, since micropropagation is a convenient technique of vegetative propagation that shows a number of interesting advantages, mainly for woody fruit trees. However, only few studies can be found in the literature on the field performance of micropropagated trees. In this work, the performance of different micropropagated fruit-tree rootstoc...

Winter pruning has been a common practice in peach. Twig topping associated with it, but this used at the same intensity, regardless of cultivar. Therefore, study aimed evaluating productive behavior and quality ‘Maciel’ peach grafted on ‘Capdeboscq’ ‘Okinawa’ (P. persica) as rootstocks, when they were submitted to different twig intensities winter pruning. The following three evaluated: short ...

The aim of this study was to evaluate the genotypes developed by Peach Breeding Program at Federal University Viçosa, as regards resistance M. incognita. Six rootstocks propagated cuttings (713-07, 713-13, 913-3, 913-6, 913-11 and 913-17) two seeds (‘Okinawa’ hybrid between scion cultivars Aurora 2 x 1), were evaluated. experimental design randomized block with five replicates one plant per uni...

Peach production in the USA has been decline recent decades due to poor fruit quality, reduced consumption and increased cost of production. Productivity quality can only be enhanced orchard through optimizing preharvest factors such as design training systems. Transition from low-density plantings (LDP) high-density (HDP) peach is associated with availability reliable size controlling rootstoc...
