Productive and vegetative performance of peach trees grafted on six rootstocks in a replanting area PAB
Almeida,Gustavo Klamer de; Marodin,Gilmar Arduino Bettio; Queiroz,Henrique Thomas; Gonzatto,Mateus Pereira.
Abstract: The objective of this work was to evaluate the productive and vegetative performance of the Maciel and Chimarrita peach tree cultivars grafted on six rootstocks, in a replanting area. The experiment was carried out in an area that had been previously cultivated with peach trees for more than 15 years in the municipality of Eldorado do Sul, in the state of Rio Grande do Sul, Brazil. The Maciel and Chimarrita peach tree cultivars were grafted on 'Aldrighi', 'Capdeboscq', 'Okinawa', 'Flordaguard', 'Nemaguard', and 'Umezeiro'. The 'Umezeiro' rootstock caused high plant mortality in both scions, as well as low productivity and higher alternate bearing; it also affected the qualitative and ripening attributes of the fruits of 'Chimarrita'. The...

Woody community dynamics in two fragments of "cerrado" stricto sensu over a seven-year period (1995-2002), MA, Brazil Rev. Bras. Bot.
Aquino,Fabiana de Gois; Walter,Bruno Machado Teles; Ribeiro,José Felipe.
This study was conducted in two fragments of "cerrado" stricto sensu in the Gerais de Balsas Colonization Project, located in southern Maranhão, Brazil. The objective was to evaluate the dynamics of the woody plant community, over seven years (1995-2002). Four transects of 160 × 20 m were monitored. All woody plants with a stem diameter > 3 cm, at 0.30 m above ground level, were recorded. In 1995, 983 and 1,177 stems were sampled in fragments 1 and 2, respectively; in 2002, 1057 and 1406 stems were sampled in the same fragments. In 1995, the Shannon diversity indices (H') were 3.07 and 3.33, in fragments 1 and 2, respectively, reaching their maximum value in 2002 of 3.11 and 3.35. The community of fragment 1 showed an increase of 7.5% in density and...
