Conteúdo:  AbstractResin tapping is an activity that aims to extract resin from trees, and thususe this product industrially. The species most used for resin tapping in Brazil is Pinus elliottiivar, elliottii. The extracted resin is basically composed of rosin and turpentine, which are used by thechemical industry. Although the main resin processes currently used are well known, new systems must be tested, such as the closed system and new compositions of stimulating pastes. These new processes and the new compositions of stimulatingpastes can make the resintappingeven more efficient and profitable. Therefore, our goal was to evaluate the effect on resin production withdifferentcompositions of stimulant pastes in resin extraction, in a closed "borehole" resin system,at differentcollection times, intrees from a population of 10-year-old Pinus elliottiivar. elliottiiplanted in Itapetininga, São Paulo. According to results, the effect of stimulating paste 4 (30% jasmonate, 4% naturoil and water) and paste 6 (30% jasmonate, 4% adhesive spreader and water) was evident in the highest production average resin per tree. Resin tappingin a closed process can be a good alternative for producers to better control the resin production system. The development of the chemical industry thatuses products derivedfrom resin and the growth of different markets, with considerable social, economic and environmental impacts, depends on future research and generation of technology for the production of resin ... Mostrar Tudo

Título:  Sewage sludge compared with other substrates in the inoculation, growth, and tolerance to water stress of Samanea saman.
Ano de publicação:  2021
Fonte/Imprenta:  Water, v. 13, 1306, 2021.

Conteúdo:  This study evaluated the initial growth and tolerance to water stress after planting Samanea saman seedlings produced with different substrates and inoculation patterns. The experiment used a factorial design (3 × 3), with three substrates: standard (67% subsoil + 33% cattle manure), a commercial substrate (composed mainly of peat), and treated sewage sludge; and three inoculation patterns: control (no inoculation), fertilized (no inoculation + chemical fertilization), and inoculation with nitrogen-fixing bacteria and arbuscular mycorrhizal fungi. The seedlings were planted in plastic pots inside a greenhouse. They received irrigation after planting and were submitted to water deficit for 35 days, followed by rehydration for 31 days. The inoculation promoted higher height and biomass for seedlings produced in the standard substrate. In the sludge, the roots biomass decreased when fertilized or inoculated. Seedlings grown in sludge showed higher height and biomass before planting and at the end of the experiment. Although, after rehydration, the height increment was similar for the sludge and the standard substrate. Seedlings grown with the commercial substrate are not recommended for planting sites subjected to water deficit. The standard substrate with inoculation and the sludge without inoculation or fertilization produced seedlings that showed better recovery and growth after water deficit.
