“…Para Williams (1977), a produção de pólen das espécies silvestres é superior às cultivares comerciais, recomendando 2 a 4 polinizadoras para compensar as diferenças de coincidência da floração.…”

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 condições climáticas do Sul do Brasil, em Caçador-SC (latitude 26º42'32" sul, longitude 51º00'50" oeste e altitude de 960 metros). As macieiras silvestres estudadas foram M. atrosanguinea, M. baccata, M. eleyi, M. floribunda, M. hopa, M. platycarpa, M. robusta, 'John Downil', 'Prof. Spengler', 'Milalew imuni', 'Profusion', 'Winter gold' e 'Yellow Siberian'. As espécies silvestres apresentaram grande variabilidade na época de florescimento e na duração do mesmo ao longo dos anos. A maior coincidência do período de floração e com maior regularidade ao longo dos anos foi obtido entre às cultivares Gala e Fuji. 'Prof. Spengler', 'Profusion', 'Winter gold' e 'John Downil' são as espécies silvestres de macieira com maior potencial de utilização como polinizadoras, podendo ser utilizadas complementarmente para polinização das cultivares Gala e Fuji. As espécies M. hopa, M. eleyi e M. atrosanguinea, devido à alta densidade de floração, podem ser utilizadas como segunda opção para a polinização das cultivares Gala e Fuji.

PHENOLOGY OF WILD APPLE SPECIES LIKE POLLINATORS OF GALA AND FUJI CULTIVARSABSTRACT -The correct choice of pollinator cultivars is an important management factor for obtaining high productivity in apple trees. Many apple production regions in the world adopt wild apple species with the specific purpose of pollination. However, there is little information about the use of this species in the climatic conditions of South Brazil. The objective of this work was to evaluate the phenological behaviour of thirteen wild apple species in relation to the fowering compared to Gala and Fuji cultivars, during seven years (2001)(2002)(2003)(2004)(2005)(2006)(2007). All species and apple cultivars studied were conduced on M-9 rootstock. The wild apple species showed high variability at flowering and length throughout the years. The major overlap of the flowering period and major regularity throughout the years was obtained between Gala and Fuji cultivars. 'Prof. Spengler', 'Profusion', 'Winter gold' and 'John Downil' are the wild apple species with the greater potential of use like pollinators, which can be used like a pollination suplement of Gala and Fuji cultivars. The species Malus hopa, Malus eleyi and Malus atrosanguinea can be used like second option for pollination of Gala and Fuji cultivars because of the high blossom density.

“…Normal (EMLA) Cox is not completely self-incompatible and can give a reasonable set with its own pollen in some years. This is probably largely a temperature dependent effect (WILLIAMS • MAIER, 1977). Therefore there must be modifying factors affecting the genetic basis of the poly-allelic, homomorphic, gametophytic S allele incompatibility system thought to exist in Cox (DE NETTAN-COURT, 1977) and they, or the genetic system itself, could be subject to change by gamma radiation.…”

“…Normally the pollinated stigma is covered by a number of pollen grains far in excess (up to 100 fold) of the two grains needed to fertilize the two ovules per style, but remarkably enough only a limited number of tubes reach the style base, the rest apparently slows down and stagnates higher up (MODLIBOWSKA, 1945;MON-TALTI & FILIPI, 1983;VISSER & OOST, 1982;WILLIAMS & MAIER, 1977).

M&s, apple, Pyrus, pear, double pollination, pollination interval, temperature, pioneer pollen, seed set first pollen, seed set second pollen. SUMMAR'r Double pollinations of apple and pear may double the seed production, to which the second pollen can contribute 3 times as many seeds as the first (pioneer)pollen, when the interval between pollinations is long enough (48 h) at low (k?' 10°C) or short enough (7 h) at high ('2 20°C) temperatures. With shorter or longer intervals, the contribution of the second pollen to seed production diminishes. The dominance ofthe second pollen was attributed to promotion by the first one, the second pollen probably being optimally stimulated when the tubes of the first have passed about 1/3rd of the style. It is concluded that the effectiveness of the pioneer pollen method to overcome incompatibility, depends on whether the interval between pollinations can be usefully adjusted to both the environmentally (temperature) and inherently determined rate of pollen tube growth of the species.
