This study aimed to estimate the biomass of dry branches of Pinus plantations maestrensis Bisse inGranma province. To which 138 trees were felled types selected from the execution of a simple random sample of 40 stands; which were pruned and defoliated, carrying out weighing separately biomass branches of each of the same, determined from the moisture content of representative samples of the branches taken at random and dried in stove at 105 ° C until bring to constant weight, and then convert the values to dry weight. To estimate biomass of dry branches four regression models, where the model presented better goodness of fit was logarithmic, with coefficient of determination and adjusted coefficient of determination of 94.4 and 94.3%, highly significant parameters were evaluated (P 0.001) and lower index value Furnival. |
