“…Inga edulis is in the Fabaceae within the subfamily Caesalpinioideae [17]. It is an early successional native tree species with high rates of photosynthesis and growth [18]. I. edulis is also a domesticated crop, and trees growing in and around agricultural settings may have slightly lower allelic diversity versus wild populations [19], which may make these individuals more prone to suffering outbreaks, though this has not been tested.…”

For decades, outbreaks of insect herbivores in tropical forests were considered unusual or rare events primarily because of high plant diversity and the top-down impact of enemies. An alternative explanation is that these outbreaks are common but occur on sparsely distributed hosts high in the canopy and at scales of one or a few individual trees. Here, we report an outbreak of a saturniid in the genus Citioica Travassos & Noronha near the Amazon Basin of Ecuador on a single tree of Inga edulis Mart. The outbreak caused near complete defoliation (>90% leaf loss) and did not occur on nearby conspecifics. This is only the twenty-third documented case of a saturniid outbreak, of which more than 60% occurred in tropical habitats. This is the first report of an outbreak on a single tree. Members of the local indigenous communities are well aware of these Citioica outbreaks and collect these caterpillars for food whenever outbreaks are detected, suggesting that these isolated outbreaks are fairly common. Further research is required to explore the possibility that insect outbreaks in tropical forests may be more common than previously suspected but occur over very small spatial scales undetected high in the forest canopy.

“…Nesse contexto, as espécies do gênero Inga Mill têm sido amplamente usadas em reflorestamentos, na produção de energia e na alimentação, por suas sementes apresentarem sarcotesta comestível (FERNAN-DES; COSTA; LOPES, 2016). Além disso, são utilizadas em programas de arborização e sistemas agroflorestais, especialmente em regiões tropicais ( JAQUETTI; GONÇALVES, 2017). As sementes constituem a principal via de propagação de espécies arbóreas tropicais, além de ser o método mais barato e acessível para produção de mudas (SILVA et al, 2016).…”

O ingazeiro (Inga ingoides (Rich.) Willd.) é uma frutífera utilizada na alimentação, reflorestamento e recuperação de áreas degradadas. Aliado a isso, as sementes do gênero Inga são recalcitrantes, que dificulta o armazenamento. Desse modo, objetivou-se avaliar a qualidade fisiológica de sementes de I. ingoides armazenadas em geladeira (5,0 ± 2 °C) e câmara fria nas temperaturas de 0,0 ± 2 e 15,0 ± 2 °C durante 28 dias, bem como a qualidade inicial das plântulas postas para germinar em casa de vegetação e laboratório. O experimento foi conduzido no Laboratório de Análise de Sementes, pertencente ao Departamento de Fitotecnia e Fitossanidade, da Universidade Estadual do Maranhão, São Luís (MA). Os frutos foram coletados no município de São Luís, sendo realizado o beneficiamento manual em laboratório e depois retiradas amostras de sementes das quais montou-se o teste de germinação e emergência (testemunha), o restante das sementes foi acondicionado em caixas do tipo gerbox e armazenado em geladeira (5 °C e 47% de umidade relativa - UR); câmara fria (0,0 °C e 49% UR) e câmara fria (15,0 °C e 55% UR). Posteriormente, foram feitos testes: teor de água, germinação, emergência, índice de velocidade de germinação e de emergência, comprimento plântulas da germinação e de emergência e massa seca de plântulas da germinação e da emergência. O armazenamento das sementes de ingá é viável por duas semanas em geladeira sem perda na sua qualidade fisiológica e postas para germinação em casa de vegetação.

“…Increased drought resistance after fertilization has been reported to be due to the enhanced quantum yield and photosynthesis (15,16). Studies on tropical environments have demonstrated the synergistic effects of multiple-nutrient fertilization on biomass growth during forest restoration with leguminous trees (17,18). However, only a few studies have evaluated the effects of combined drought and nutrient stresses on growth and photosynthetic perforance.…”

The ability of species to adjust their light energy uptake is determined during plant establishment and development. Changes in resource availability may impact energy fluxes and photosynthesis. General and specific variations in chlorophyll a fluorescence under high vs. low water and nutrient conditions have been studied. N2-fixing leguminous trees, which are commonly used in tropical forest restoration, seem to be very well adapted to degraded ecosystems. To understand the effects of biological nitrogen fixation on Chl a fluorescence variables, three of the six Fabaceae species selected for this study were N2-fixing species. Additionally, the correlation among Chl a fluorescence and growth, photosynthesis and nutrient levels was evaluated. A 24-month forest restoration experiment was established, and data on dark-adapted Chl a fluorescence, photosynthesis, diameter growth and foliar nutrients were collected. Multivariate analysis was performed to detect the effects of seasonality and fertilization. Under high water- and nutrient-availability conditions, plants exhibited enhanced performance index values that were correlated with electron transport fluxes. Under drought and nutrient-poor conditions, most species exhibited increased energy dissipation as a method of photoprotection. Great interspecific variation was found; therefore, species-specific responses to the test conditions should be considered in future studies. N2-fixing species showed increased performance index and maximum fluorescence values, indicating their ability to colonize high-light environments. Negative correlations were found between photosynthesis and trapped fluxes and between diameter growth and initial fluorescence. Electron transport fluxes were positively correlated with growth. Given the different responses identified among species, Chl a fluorescence is considered a cost-effective technique to screen for seasonality, nutrient and N2-fixing species effects and should be considered for use during forest restoration. Finally, including N2-fixing species and multiple fertilization treatments in related studies may greatly facilitate the restoration of biogeochemical cycles in the tropics.
