| A expansão da cultura da seringueira no Estado de São Paulo foi analisada por meio de dados anuais da produção municipal disponibilizados pelo IBGE. Os dados de quatro anos (1988, 2003, 2008 e 2013) referentes à área colhida com seringueiras, quantidade produzida de látex coagulado e rendimento médio da produção de quatro anos foram visualizados em mapas coropléticos de municípios e regiões de governo do estado. Conclui-se que a produção paulista ocorre na porção oeste do estado, com grande concentração nas regiões tradicionais de cultivo: São José do Rio Preto, Barretos e Votuporanga, regiões que desde os anos 1990 dominam amplamente a produção. A quantidade produzida, a área colhida e o rendimento médio da produção no estado apresentaram crescimentos... |

| Rubber production is dependent on the availability of carbohydrates in the tissues engaged in latex synthesis. In this study three rubber tree clones were used to study the protein profile, the activities of invertase and sucrose synthase in the latex and anatomical characteristics of the bark, as well as to establish a possible relationship with latex production. The clones used in the study, RRIM 600, GT 1 and Fx2261, differed in latex productivity, from high to low in this order. Although present, few differences were observed in the latex protein profile obtained by denaturing electrophoresis. The activity of neutral invertase was higher than the acidic isoform, and both activities were higher in the most productive clones RRIM 600 and GT 1. The same... |

| In this study, proteins extracted from laticifer cells of three plants were examined by electrophoresis, mass spectrometry (MALDI-TOF) and characterized in respect of proteolytic, chitinolytic and anti-oxidative activities by means of zymography and colorimetric assays. Acidic proteins with molecular masses between 12.5 and 74.5 kDa predominated in laticifers of P. rubra. This profile was not found in laticifers of C. grandiflora and E. tirucalli. The later was poor in respect of proteins. Strong anti-oxidative activity of superoxide dismutase (E.C. 1.15.1.1) was detected in P. rubra and C. grandiflora latices, and to a lesser extent ascorbate peroxidase (E.C. 1.11.1.1) and isoforms of peroxidase were seen. Catalase (E.C. 1.11.1.6) was detected only in... |

| Eleven Hevea brasiliensis clones were evaluated for clonal stability of latex yield. A randomized complete block design was used with four replicates, two locations, seven years and three periods per year. Stability analysis was based on clone x year and clone x year x location interactions. Five stability parameters viz environmental variance, shukla's stability variance, regression of clonal latex yield on environmental index, variance due to regression and variance due to deviation from regression were applied. There was significant clone x environment effect at the two levels of interaction. Among the eleven clones, C 162 was outstanding for clonal stability and it can serve as donor parent for stability alleles. Three clones (C 76, C 150 and C 154)... |
