“…The accumulation of dry matter in the berries increased as the maturation progressed, attaining the highest values in the nal weeks of maturation process: 45-47 WAF for Beira Rio 8, A1, Pirata Bamburral and Clementino, (early/medium and medium maturation cycle genotypes), and 49 WAF for late maturation P1 genotype. The DM accumulation was initially the highest for berry and bean DM per berry (33)(34)(35)(36)(37)(38)(39)(40)(41), while the highest increases in husk DM accumulations happened latterly (41)(42)(43)(44)(45)(46)(47)(48)(49). High late husk DM investments can be related to necessity of the embryo protection, as one theme for eventual future research.…”

Knowledge about the dynamics of dry matter (DM) accumulation in the berry components (bean and husk) throughout maturation process could help in the definition of the most adequate moment for the harvest of each genotype. For that, were studied the berry, bean, and husk DM accumulation dynamics during the fruit maturation process of six Coffea canephora genotypes, to identify the best berry harvesting stage. Berry samples were collected every two weeks at nine maturation moments/stages. The DM accumulation was initially the highest for berry and bean, while the highest increases in husk DM happened latter. Second order polynomial regressions were fitted for berry, bean, and husk DM accumulation over time. The berry, bean and husk DM accumulation increased as fruit maturation progressed, attaining the highest values in the final stages of red berries. Beira Rio 8 genotype presented the highest DM accumulation in berries, beans, and husk. Bamburral and P1 showed the lowest berry fresh mass (FM) to bean DM ratios, while A1 showed the greatest berry FM to bean DM ratio. Not only the absolute berry and bean yield must be considered for high productive genotype selection, but also bean DM performance must account in the characterization of commercial coffee yields.

Kaolin particle film mitigates supra-optimal temperature stress effects at leaf scale and increases bean size and productivity of Coffea canephora

et al. 2023

Summary In young plants of Coffea canephora, fine particle film based on calcined kaolin (KF) causes a decrease in leaf temperature (Tleaf), minimizing the damages to the photochemical apparatus, especially in summer season, but no report about the ecophysiological responses to KF over phenology is available on this species. We hypothesized that greater ecophysiological effects of KF would occur during the summer phenophase of leaf area and berry expansion (BE) compared with autumn berry maturation phase (BR), and that those benefits will have impact on bean productivity and physical quality. In this sense, the present study aimed to analyze the effects of KF on some ecophysiological parameters in the last phenophases of C. canephora biennial cycle, bean productivity, and bean size classification. During the complete phenological cycle, eight applications of KF were performed, totaling 80 kg of KF ha−1 in two years. KF applications and ecophysiological measurements occurred during the BE and BR phenophases. Firstly, we documented temporal dynamics in responses of field-grown C. canephora adult plants to KF application. KF reduced Tleaf and crop water stress index and increased the thermal index of relative stomatal conductance and relative chlorophyll content (SPAD index) observed in the autumn BR (opposite to young plants). The positive impact of KF on chlorophyll a fluorescence was proportionally similar among the observed phenophases. Secondly, KF increased bean size 16 by 50% and increased total productivity. The plants treated with KF increased productivity by 1.7 t ha− commercially useful bean mass compared to the control. The kaolin dose of 40 kg ha−1 distributed four times per year was highly effective as a protection strategy against high-light and elevated Tair.

Environmental vulnerability refers to the susceptibility of a region to damage when it is subjected to natural or anthropogenic actions. The assessment of environmental vulnerability in lakes is an important tool to assist managers in planning and intervening for sustainable production and environmental preservation. The combination of geotechnologies, fuzzy logic and the analytic hierarchy process (AHP) has been applied by professionals and researchers to improve the work and research conducted in various areas and environments. In this context, the objective of this work was to map the environmental vulnerability of a lake and its surroundings through fuzzy logic and the AHP method. The study area comprises the Juparanã Lagoon Drainage Surface (JLDS), Espírito Santo state, Brazil. A survey of the physical characteristics of the watershed (drainage surface) that feeds the Juparanã Lagoon was carried out and also of the land use of this surface. To achieve the proposed objectives, the following methodological steps were implemented: (a) delimitation of watersheds, (b) spatialization of Permanent Preservation Areas (APP) based on the Brazilian Forestry Code (Law nº 12,651/2012), (c) application of logic fuzzy and AHP to spatialize the environmental vulnerability and (d) application of an evaluation of environmental vulnerability to the Preservation Areas (APP). Environmental vulnerability was modeled using Euclidean distance analysis, fuzzy logic and the AHP method, as proposed by Saaty (1977). For the development of this work, geotechnologies were used, with special emphasis on the use of the free software QGIS. The analysis revealed that 31.20%, 32.86% and 20.93% of the JLDS have very high, high and medium vulnerability, respectively. The evaluation of the environmental vulnerability of the APP showed that there is protection in the APP of the JLDS at rates of 47.35%, 34.05% and 14.5% for very high, high and medium vulnerability classes, respectively. The difficulties encountered were related to the lack of studies in the area of environmental vulnerability with a particular focus on lagoons. Here, for the first time, we perform a photointerpretation of the surroundings of Juparanã Lagoon. An important improvement measure would be the application of a temporal analysis to assess the dynamics of environmental vulnerability over time, considering socioeconomic, climatic and environmental changes. This would provide a more complete understanding of the distribution of environmental vulnerability in the study area. The methodology can be adapted to consider different scales of analysis, from local to regional, national and global scales, to assess environmental vulnerability at various scopes and levels of complexity. It can also be adapted to include local communities and governments.
