Zusammenfassung: | The different propagation systems for litchis are reviewed. After examining the main morphological and developmental characteristics of the plant and the description of the structures and materials, including types of substrate required for the propagation of this species, the different methods for its propagation are discussed. Propagation by seeds is only used for breeding or research purposes or for raising rootstock for grafting. Although propagation by cuttings is done in many countries and stooling has been reported as highly successful in India, air layering is the most common commercial way of propagation for this species. Despite that the cambium activity varies from place to place around the stem with only 30% of the cambium being active at any one time grafting is of current use in China. Index terms: Air layering, Litchi chinensis Sonn, propagation. Foram estudados os diferentes tipos de propagacao da lichieira. Depois de examinar as principais caracteristicas morfologicas e de desenvolvimento da planta e de uma descricao das estruturas de propagacao, materiais e tipos de substrato necessarios para esta especie, descrevemse os diferentes metodos de propagacao desta frutifera. A propagacao por semente usa-se apenas para melhoramento, pesquisa ou obtencao de porta-enxertos. Embora a propagacao por estaquia seja usada em varios paises e que a propagacao seja por mergulhia e praticada na India com grande sucesso, a alporquia e o sistema de propagacao comercial mais usado no mundo para esta especie. Ainda que a atividade do meristema varie em torno do caule, e apenas 30% do mesmo esteja ativo, a enxertia e pratica comum na China. Termos para Indexacao: Alporquia, Litchi chinensis Sonn, propagacao. |
