Zoneamento climático para plantio experimental de Pinus maximinoi no Estado de São Paulo

The state of Sao Paulo has a wide climatic diversity which certainly influences productivity and species adaptation in forest plantations and places for plantation and experimentation must be carefully chosen. The objective of this study was to identify climatically homogeneous regions in the state of Sao Paulo, based on data collected at several experimental stations of Sao Paulo State Forest Institute to support deployment of Pinus maximinoi for experimental plantings. Thirty experimental areas and climatic data for each meteorological station were subjected to cluster analysis interpreted according to the resulting dendrograms. Climatic requirements for this species were verified in the scientific literature and assessed in experimental plantings. The most adequate experimental stations for P. maximinoi are in Angatuba, region that includes Buri, Piraju, Itapeva, Avare, Itapetininga, and Itarare Stations. The climate in the region is Cwa. The stations in the group including Bebedouro, Sao Jose do Rio Preto, and Ilha Solteira are not recommended for the species because of the warmer climate and water stress during the summer months. Campos do Jordao Station is also not recommended due to frequent frosts. For intermediate areas, could be identified specific genotypes that are adaptable to each specific climatic conditions. doi: 10.4336/2012.pfb.32.69.79
