Comportamento vegetativo de seis cultivares de coqueiro-an?o (Cocos nucifera L.), em Santo Ant?nio de Leverger - MT

摘要

The use of cultivars of coconut palm suitable to the edaphoclimatic conditions of a region is of basic importance for the attainment of high productivity. With the objective to study the vegetative behavior of six cultivars of dwarf coconut palm was carried out an experiment in Santo Ant?nio de Leverger - Mato Grosso State. The cultivars studied were: An?o Vermelho da Malásia (AVM), An?o Verde de Jiqui (AVeJ), An?o Vermelho de Gramame (AVG), An?o Vermelho de Camar?es (AVC), An?o Amarelo de Gramame (AAG) and An?o Amarelo da Malásia (AAM), planted in May of 1998, in which were evaluated from April of 1999 till December of 2000 the following characteristics: girth circumference (CC), number of emitted leaves (NFE), number of alive leaves (NFV), number of dead leaves (NFM), number of leaflets in the leaf 3 (NFoF3), length leaflets in the leaf 3 (CFoF3), leaf 3 length (CF3) and petiole length in the leaf 3 (CPF3). It was utilized a randomized block design with four repetitions, having in each plot 16 plants. For the girth circumference (CC), number of leaflets in the leaf 3 (NFoF3) and leaf 3 length (CF3), the AMM presented the lessers values. The AVeJ and AVM were more vigorous when compared to AAM, AAG and AVC.
