RESUMO

O estudo teve como objetivo avaliar o estoque mensal e anual de serapilheira e sazonalidade em
duas fitofisionomias (Cerrado stricto sensu e Mata de Galeria) e em um povoamento de eucalipto,
localizados na Fazenda &#xC1;gua Limpa, DF. O estoque de serapilheira foi coletado mensalmente,
pelo per&#xED;odo de um ano, com aux&#xED;lio de um gabarito met&#xE1;lico de 0,25 m2. O material foi separado
manualmente nas fra&#xE7;&#xF5;es folhas, cascas, galhos, ra&#xED;zes, flores/frutos e material particulado.
O estoque de serapilheira na Mata de Galeria (9,36 t ha-1) foi estatisticamente igual ao observado
no povoamento de eucalipto (9,12 t ha-1), valores maiores que o verificado no Cerrado T&#xED;pico
(6,08 t ha-1). A fra&#xE7;&#xE3;o folha apresentou maior quantidade nas fitofisionomias e no povoamento
quando comparada &#xE0;s demais fra&#xE7;&#xF5;es. Verificaram-se dois padr&#xF5;es divergentes de sazonalidade
do estoque de serapilheira: maior estoque no Cerrado T&#xED;pico e no povoamento de eucalipto na
esta&#xE7;&#xE3;o seca e maior estoque na Mata de Galeria na esta&#xE7;&#xE3;o chuvosa.

Litter Stock in Three Forest Types in Cerrado at Distrito Federal

ABSTRACT

The aim of this study was to evaluate the monthly and annual litter stock, and the seasonality
in two phytophysiognomies (Cerrado stricto sensu and Gallery Forest) and one eucalyptus
plantation, located in Fazenda &#xC1;gua Limpa, DF. The litter stock was monthly collected by using
a metal jig of 0.25 m2, during one year. The material was manually sorted into leaves, bark, twigs,
roots, flowers/fruits and particulate matter. There were no significant differences in the litter
stock between the Gallery Forest (9.36 t ha-1) and the eucalyptus plantation (9.12 t ha-1), which
were both higher than the Cerrado stricto sensu (6.08 t ha-1). The leaf fraction presented a larger
amount in the three vegetation types when compared to the other fractions. There were two
different patterns of litter stock seasonality: higher litter stock in the Cerrado stricto sensu and
eucalyptus plantation in the dry season; and higher stock in Gallery Forest in the rainy season.
