Fenologia de espécies silvestres de macieira como polinizadora das cultivares gala e fuji

Abstract: RESUMO -A escolha correta de cultivares polinizadoras na macieira é determinante para a obtenção de altos rendimentos. Muitas regiões produtoras de maçãs do mundo utilizam macieiras silvestres com o fim específico de polinização, porém existem poucas informações quanto ao uso dessas espécies nas condições climáticas do Sul do Brasil. O objetivo deste trabalho foi avaliar o comportamento fenológico de espécies silvestres de macieira quanto à floração em comparação as cultivares comerciais 'Gala' e 'Fuji', nas c… Show more

“…Many studies, performed on different plants, suggest various hypotheses for low fruiting. Among them are: a shortage or lack of pollinators (Manente-Balestieri and Machado, 1999;Paiva et al, 1999;Kiill and Drumond, 2001;Tavares et al, 2002;Nogueira and Arruda, 2006;Petri et al, 2008), unavailability of nutrients in the soil (Ferreira et al, 2003), herbivory and predation affecting the production and flower or fruit viability (ManenteBalestieri and Machado, 1999;Vieira and Grabalos, 2003;Nogueira and Arruda, 2006;Carvalho et al, 2007;Aguiar and Gaglianone, 2008), lack of resources available on the plant (Manente-Balestieri and Machado, 1999;Vieira and Grabalos, 2003;Nogueira and Arruda, 2006;Carvalho et al, 2007;Aguiar and Gaglianone, 2008), selfpollination, since the species are normally cross-pollinated (Nogueira and Arruda, 2006) and abiotic factors such as temperature, humidity and precipitation (Ferreira et al, 2003;Nogueira and Arruda, 2006;Pereira and Mayer, 2008). Soil characteristics such as pH, aeration, temperature and nutrient availability may also directly affect the plants reproductive success by influencing the production and viability of the fruits (Ferreira et al, 2003).…”

“…Kiill and Drummond (2001) in their study of Gliricidia sepium, Tavares et al (2002) with pears and Paiva et al (1999) with acerolas). This failure is probably due to the shortage or deficiency of pollinators (Manente-Balestieri and Machado, 1999;Nogueira and Arruda, 2006;Petri et al, 2008). One important possibility is the changing regional landscape.…”

“…The longer the flowering period the more difficult will be the carrying out of some cultural practices such as fruit thinning and diseases control due to the occurrence of different phenological stages in the same tree. Under warm winter conditions, where the chilling exigencies are not completely satisfied, cultivars with distinct chilling requirements showed immense variability in the flowering period from year to year (Petri et al 2008). The lack of synchrony of flowering between cultivars is clearly observed in the control treatment (Fig.…”

“…A seleção 140/279, embora tenha mostrado coincidência com o período de abertura das primeiras flores de 'Daiane', apresentou comportamento fenológico muito variável nos diferentes anos em que foi avaliada. Isso confere a ela um aspecto negativo, pois é extremamente importante que a polinizadora apresente estabilidade na coincidência de floração com a cultivar produtora ao longo dos anos (PETRI et al, 2008) e garanta sempre disponibilidade de pólen em todo o período de florescimento da cultivar produtora.…”
