FARIA, WALDIR SEBASTIÃO DE; GAIVA, HILTON NEY  and  PEREIRA, WALTER E.. Behavior of five genotypes of coconut tree (Cocos nucifera L.) in the phase of germination and seedling growth, under different systems of production . Rev. Bras. Frutic. [online]. 2002, vol.24, n.2, pp.458-462. ISSN 0100-2945.

With the objective to evaluate the performance of five genotypes of dwarf and hybrids of coconut tree: dwarf green of Jiqui (AVeJ), red dwarf of Gramame (AVG), dwarf yellow of Malaysia (AAM), hybrid of red dwarf Gramame x giant Brazil of Forte beach (AVG x GBrPF) and the hybrid of dwarf yellow of Gramame x giant of the African west (AAG x GOA), in the germination and growth stage, in different production systems, an experiment was carried out in August of 1998, in the Experimental Station of the Faculdade de Agronomia e Medicina Veterinária of the Universidade Federal of Mato Grosso, located in Santo Antônio de Leverger. It was evaluated the performance of five genotypes of coconut tree in the germination and growth stage of seedlings originated from seeds placed in the horizontal and vertical positions, and kept at 50% of shade or full sun. Those factors were combined factorially, resulting in 20 treatments, which were arranged in the completely randomized design. The evaluated characteristics were: accumulated germination, percentage of germination, percentage of seedling capable of being transplanted for the field, seedling height, number of leaves, circumference of the girth, weight of the seedling and weight of the aerial part. The hybrid (AAG x GOA) and the AVG presented, respectively, larger and smaller values for the characteristics: germination percentage, percentage of seedling capable of being transplanted for the field, number of leaves, circumference of the girth and of the seedling heights to the 30, 60 and 90 days of nursery. The seedlings of larger weights corresponded to the hybrid (AVG x GBrPF), and the one of smaller weights, to the AAM. The hybrid AVG x GBrPF produced seedlings that presented heavier aerial part and AVG the lightest. The seedlings produced from the seeds under shade of 50% presented larger heights and weights. The seeds germinated in the horizontal position produced seedlings higher to the 30 and 60 days of nursery, and larger number of leaves.
