ABSTRACT - The objective of this work was to evaluate the resistance of chickpea (Cicer arietinum) genotypes to the root-knot (Meloidogyne javanica) and root-lesion (Pratylenchus brachyurus) nematodes, as well as to verify how these species affect this crop in field conditions. The experiment was carried out in the Cerrado biome in the state of Goiás, Brazil, in a naturally infested area. The BRS Aleppo, Cícero, BRS Cristalino, BRS Toro, and BRS Kalifa cultivars and the Jamu 96 genotype were evaluated. The assessed variables were: nematode reproduction factor, fresh mass of the aerial part of the plant and of the root system, dry matter of the aerial part of the plant, total dry matter of the plants, chlorophyll index, height of the plants, and grain yield. Pratylenchus brachyurus multiplies more than M. javanica, decreasing root fresh matter, plant height, and grain yield. All genotypes are resistant to M. javanica, especially Jamu 96 and cultivar BRS Kalifa. Jamu 96 and
cultivar Cícero are susceptible to P. brachyurus. BRS Kalifa is the cultivar most resistant to both nematodes and shows the highest grain yield.
RESUMO - O objetivo deste trabalho foi avaliar a resistência de genótipos de grão-de-bico (Cicer arietinum) aos nematoides da galha (Meloidogyne javanica) e das lesões (Pratylenchus brachyurus), bem como verificar como estas espécies afetam essa cultura em condições de campo. O experimento foi realizado no bioma Cerrado, no estado de Goiás, Brasil, em área naturalmente infestada. Foram avaliados as cultivares BRS Aleppo, Cícero, BRS Cristalino, BRS Toro e BRS Kalifa e o genótipo Jamu 96. As variáveis avaliadas foram: fator de reprodução dos nematoides, massa fresca da parte aérea e do sistema radicular, matéria seca da parte aérea, matéria seca total das plantas, índice de clorofila, altura das plantas e rendimento de grãos. Pratylenchus brachyurus se multiplica mais do que M. javanica e diminui massa fresca da raiz, altura da planta e rendimento de grãos. Todos os genótipos são resistentes a M. javanica, principalmente Jamu 96 e a cultivar BRS Kalifa. Jamu 96 e a cultivar Cícero são suscetíveis a P. brachyurus. BRS Kalifa é a cultivar mais resistente a ambos os nematoides e apresenta maior rendimento de grãos.

Information regarding the spatial distribution of palm trees in tropical forests is crucial for commercial exploitation and management. However, spatially continuous knowledge of palms occurrence is scarce and difficult to obtain with conventional approaches such as field inventories. Here, we developed a new method to map Amazonian palm species at the individual tree crown (ITC) level using RGB images acquired by a low-cost unmanned aerial vehicle (UAV). Our approach is based on morphological operations performed in the score maps of palm species derived from a fully convolutional neural network model. We first constructed a labeled dataset by dividing the study area (135 ha within an old-growth Amazon forest) into 28 plots of 250 m×150 m. Then, we manually outlined all palm trees seen in RGB images with 4 cm pixels. We identified three palm species: Attalea butyracea, Euterpe precatoria and Iriartea deltoidea. We randomly selected 22 plots (80%) for training and six plots (20%) for testing. We changed the plots for training and testing to evaluate the variabilityn, in the classification accuracy and assess model generalization. Our method outperformed the average producer?s accuracy of conventional patch-wise semantic segmentation (CSS) in 4.7%. Moreover, our method correctly identified, on average, 34.7 percentage points more ITCs than CSS, which tended to merge trees that are close to each other. The producer's accuracy of A. butyracea, E. precatoria and I. deltoidea was 78.6 ± 5.5%, 8.6 ± 1.4% and 96.6 ± 3.4%, respectively. Fortunately, one of the most exploited and commercialized palm species in the Amazon (E. precatoria, a.k.a, Açaí) was mapped with the highest classification accuracy. Maps of E. precatoria derived from low-cost UAV systems can support management projects and community-based forest monitoring programs in the Amazon.
