Background: The açaí palm (Euterpe oleracea Mart.) is a species native to the Amazon region, where the largest stock of these palms is located in the state of Pará, Brazil. This species occurs predominantly spontaneously in the plateau and plains areas of the Amazonian estuary. Water deficit is the main limiting factor of plants, negatively regulating the growth, metabolism and productivity of crops. Aim: This study aimed to deepen the ecophysiological and biochemical responses of Euterpe oleracea Mart. to a water deficiency condition in agroforestry systems. Methods: The study was carried out in a defined period of lowest rainfall in the region, which runs from July to October, averaging 58.6 mm for those months, such as location, age, uniformity, health, development, height and diameter of the stipe, in order to determine the biochemical variables. Responses to biochemical components under water deficit such as starch, sucrose and carbohydrates increased for rachis and fruits. Results: The concentrations of ammonia and proteins increased in stems and fruits. For amino acids, the structures that accumulated these organic compounds were fruits and arrow. One of the most representative amino acids against water deficiency is proline, and its increase in plant tissues is due to osmoprotein function, especially for structures such as rachis, fruit and petioles + rachis. Conclusions: Therefore, Euterpe oleracea Mart. presents excellent physiological plasticity to deal with stressful conditions as well as adaptive behavior to overcome this deficiency.

“…Wang et al (2019) reported that DS (125 g L −1 PEG‐6000) decreased thylakoid protein components and photosynthetic performance in rice ( Oryza sativa L.) (C3) (LYP9), decreasing trimeric LHCII, PSII core, F1‐ATPase Cytb6/f complex, and PSI core binding LHCI by up to 35.25%, 58.77%, 37.8%, 63.8%, 62.9%, and 17.4%, respectively. In another study, de Oliveira et al (2019) observed the regulation of proteins related to photochemical reaction centers in Euterpe oleracea (assai palm) (C3) under DS (30% FC for 21 days), reporting lower abundance of PSI reaction center N, chlorophyll a / b binding protein 8 (at LHC1), and PSII protein D2, and higher abundance of ATP synthase CF1 ε subunit, PSI reaction center III and IV subunits, and chlorophyll a / b binding protein CP29.2 than control plants, suggesting that PSII is more prone to DS than PSI. Furthermore, severe DS (34 days) decreased the abundance of ATP synthase subunit ß and ε, ferredoxin‐NADP reductase, PSII CP43, and chlorophyll a / b binding protein CP29.2 and increased the abundance of PSI reaction center.…”

Balanced photosynthesis is essential for improved plant survival and agricultural benefits in terms of biomass and yield. Photosynthesis is the hub of energy metabolism in plants; however, drought stress (DS) strongly perturbs photosynthetic efficiency due to biochemical and diffusive limitations that reduce key photosynthetic components and close stomata. This review describes photosynthetic responses, chloroplast retrograde signalling, and genetic imprints that curtail DS damage to photosynthetic machinery. While stomatal closure, disrupted photosynthetic systems, over‐reduced electron transport rates (ETR), partial hindrance of the Calvin cycle, and reduced pigment contents strongly affect the repertoire of photosynthetic processes under DS, chloroplast retrograde signalling also has a plausible role in preserving photosynthetic capacity. Progress in agronomic, genetic engineering approaches and isoprene regulation would help to rescue photosynthetic apparatus under DS.

O açaizeiro (Euterpe oleracea Mart.) é uma espécie natural das áreas de várzea da região amazônica, sendo o estado do Pará como o maior centro de dispersão natural dessa palmeira. Grande parte de sua produção provém do extrativismo e possui potencial de incremento da produção de frutos ao projetar o cenário para o avanço do cultivo da espécie para a terra firme, mas necessita estar enquadrado nos padrões de mercado, portanto, deve-se ocorrer o aperfeiçoamento das técnicas de produção de mudas. Assim, o trabalho teve como objetivo avaliar o desenvolvimento inicial em plantas de açaizeiro, produzidas em recipientes com diferentes volumes e substratos, durante 360 dias em campo. O ensaio foi realizado no campo experimental da Embrapa Amazônia Oriental, em Belém, PA. Foram utilizadas mudas de açaizeiro da cultivar BRS Pará, produzidas em dois tipos de substratos (comercial e o convencional). Para a produção de mudas foram usados os seguintes tipos de recipientes: saco de plástico com as dimensões de 18 x 24 cm (1900 cm³), a qual é recomendada para a produção de mudas de açaizeiro e outras fruteiras e tubetes com volumes de 280, 175 e 95 cm³. O experimento foi instalado no delineamento experimental em blocos inteiramente casualizados, utilizando-se quatro repetições e cinco plantas por parcela. As avaliações em campo ocorreram a cada 60 dias após o plantio. As variáveis mensuradas foram: altura da planta, diâmetro do coleto e número de folhas. Observou-se que os tratamentos em saco de polietileno houve maior desenvolvimento nas variáveis analisadas, independente do substrato usado. Verificou-se que não houve diferença significativa entre os tratamentos resultantes de mudas produzidas em tubete. Portanto, conclui-se que as plantas de E. oleracea Mart, da cultivar BRS Pará, apresentaram maior desenvolvimento inicial quando oriundas de mudas produzidas em sacos de polietileno em relação aos demais recipientes.
