ESTIMATIVAS DO \ucdNDICE DE \uc1REA FOLIAR UTILIZANDO O LAI-2000 E FOTOGRAFIAS HEMISF\uc9RICAS EM PLANTIOS DE EUCALIPTO
No full textThe objective of this study was to estimate the Leaf Area Index (LAI)
by indirect methods in plantations of Eucalyptus clones in two distinct
physical-climatic sites, during the dry and rainy periods. The study
was performed in four young and adult Eucalyptus stands, located in Rio
Doce basin, eastern Minas Gerais state (Brazil) situated in areas of
lower and higher altitudes. Nine plots were allocated in each stand.
Experimental data were collected in months representing the driest and
the wettest periods. LAI indirect measurements were performed using the
LAI-2000 equipment and cameras with hemispherical lens. To verify the
accuracy of estimation, a destructive analysis was also performed. The
LAI measurements by the LAI-2000 was the one which best correlated with
the observed LAI (R =0.90), although the hemispherical photos had
presented good potential use. It is verified that the LAI of stands in
the higher altitudes region, surpassed those of lower altitudes, which
was also observed by the indirect methods. The destructive analysis
indicates lower values of LAI measured in the dry season although this
variation is only significant for higher altitudes. This behavior is
also observed for estimates with the LAI-2000, different from the
hemispherical photographs which did not identify seasonality of LAI.O objetivo deste estudo foi estimar o \ucdndice de \uc1rea Foliar
(IAF) por m\ue9todos indiretos em plantios clonais de eucalipto em
dois distintos s\uedtios f\uedsico-clim\ue1ticos, durante as
esta\ue7\uf5es seca e chuvosa. O estudo foi feito em quatro
talh\uf5es, dois jovens e dois adultos, localizado na bacia do Rio
Doce, leste de Minas Gerais, situados em \ue1reas de baixas e altas
altitudes. Nove parcelas foram alocadas em cada talh\ue3o. Dados
experimentais foram coletados em per\uedodos secos e chuvosos. As
medidas indiretas do IAF foram feitas usando o LAI-2000 e c\ue2meras
com lentes hemisf\ue9ricas. Para verificar a precis\ue3o da
estimativa foi realizada a an\ue1lise destrutiva. As medias do
LAI-2000 foram aquelas que melhores correlacionaram com os dados de IAF
observados (R=0,9), embora as fotos hemisf\ue9ricas apresentem bom
potencial de uso. Foi verificado que os valores de IAF dos talh\uf5es
de maiores altitudes foram maiores comparados \ue0s regi\uf5es
baixas, o que tamb\ue9m foi observado pelos m\ue9todos indiretos. A
an\ue1lise destrutiva indica baixos valores de IAF medidos na
\ue9poca seca, embora esta varia\ue7\ue3o seja significativamente
somente nos talh\uf5es das regi\uf5es mais altas. Este
comportamento \ue9 tamb\ue9m observado nas estimativas do LAI-2000,
diferente das fotografias hemisf\ue9ricas que n\ue3o identificaram
a sazonalidade do LAI
