Avanços na propagação de fruteiras no Brasil e no mundo-macieira

A produção de maçãs é uma atividade de grande importância econômica em nível mundial. A ampla disseminação e cultivo da macieira em várias regiões do mundo deve-se ao desenvolvimento de técnicas propagativas desde sua domesticação até a atualidade. A macieira pode ser propagada por sementes, com restrita a utilização em programas de melhoramento genético, e multiplicada por vários métodos de propagação vegetativa, tanto para portaenxertos como para cultivares copa. Levando-se em consideração o elevado nível tecnológico atualmente empregado na cultura da macieira, a propagação de plantas tem papel de grande relevância, no sentido de viabilizar a produção de mudas de elevado padrão morfofisiológico e fitossanitário, demando novos avanços e aprimoramentos a medida que novas cultivares copa e portaenxertos são desenvolvidos.
