“…In this context, plant markers such as brassinosteroids, polyamines, salicic acid and jasmonic acid have been mentioned as a new class of plant growth regulators related to several morphological and physiological effects on plant development. Among those effects are defense, cell division, reproduction, growth and development (FRANCISCO et al, 2008;BORCIONI;NEGRELLE, 2012;TAIZ et al, 2017). Jasmonic acid (JA) and its jasmonate derivatives are endogenous regulators of plant growth originating from linolenic acid, which occur in several plant species (FRANK;ROSS, 1991;KERBAUY, 2012).…”

Este trabalho objetivou investigar as respostas fotossintéticas em mudas de híbrido 1528 de Eucalyptus urophylla x Eucalyptus grandis submetidas à aplicação de ácido jasmônico (JA) e ﬂexões caulinares. O experimento foi conduzido em casa de sombra utilizando delineamento inteiramente ao acaso com cinco repetições de 20 mudas, com os seguintes tratamentos: T1: controle, T2: 8,0 μmol de JA e T3: 40 ﬂexões caulinares. A taxa de assimilação líquida de CO2 (A), condutância estomática (gs), concentração interna de CO 2 (Ci), taxa de transpiração da folha (E), efciência do uso de água (WUE), efciência intrínseca do usode água (iWUE) e efciência de carboxilação (Fc) foram mensuradas com o auxílio do IRGA. A dose de JA aplicada nas mudas foi insufciente para alterar as respostas fotossintéticas em relação ao tratamentocontrole. Estímulos mecânicos induzidos através de ﬂexões caulinares em mudas do híbrido 1528 de eucalipto promoveram incremento da capacidade fotossintética máxima e máxima assimilação de CO2. Porém, as mudas apresentaram redução na efciência do uso da água, ou seja, menor efciência fotossintética quando comparado com as mudas submetidas aos demais tratamentos. Mudas do híbrido 1528 de eucalipto submetidas aos estímulos mecânico e ácido jasmônico apresentaram maior respiração sob níveis baixos de ﬂuxo de fótons fotossinteticamente ativos.

Macaúba is a tropical palm native in South and Central America, and its fruits present a high-quality oil for biodiesel production. Notwithstanding, macaúba's wastes and by-products are not usually repurposed as energy sources. This study shows a bibliometric analysis to assess macaúba's current applications and to investigate other energy recovery routes for its by-products. All the investigations focused on information about the main research fields related to macaúba. The study showed that only 397 articles and reviews were published from 1900 until 2021, and Brazil is the leading publisher. Although oleic and protein macaúba's by-products are applied as animal feed, some conversion routes related to the lignocellulosic contents, present in non-edible parts, were identified thermal conversion, combustion, gasification, pyrolysis, biochemical conversion, fermentation, esterification, and anaerobic digestion.From the agricultural perspective, plant characterization, germination, embryogenesis, and seed development were also found. From the bibliometric study, the different potential applications of macaúba for energy, pharmaceutical, and food purposes were listed to support the identification of a knowledge gap on its by-products revaluation.
