1. PATH ANALYSIS OF PHYSICAL ATTRIBUTES OF CHAYOTE FRUIT
ABSTRACT Chayote is originally from southern Mexico and Guatemala and has been a staple food highly appreciated in Brazil and worldwide. This study was carried out on a Red Yellow Latosol in 2020 to investigate the relationship between the physical properties of chayote fruit of the variety Cambray and their mass, aiming to indicate criteria for direct selec

2. Hymenaea parvifolia Huber: dormancy breaking, morphology of fruit, seed and seedling
ABSTRACT The successful use of native species in conservation actions depends on basic knowledge of their biology, beginning with the identification of regenerating individuals in the field, up to the behavior and development of the species from the early stages of germination. Moreover, seed propagation and germination may be limited by the occurrence of do

3. CONTRIBUTION OF SOIL ATTRIBUTES AND MORPHOLOGICAL VARIABLES TO YIELD OF IRRIGATED GARLIC
ABSTRACT This study aimed to investigate relationships between the soil attributes that most affect garlic yield, which can be useful to choose a new area for the growing of this vegetable. We also aimed to study the effects of irrigation deficit at bulb formation stage (cloves) on final garlic quality and yield. The variables evaluated were garlic yield, ir

4. Applicability of computer vision in seed identification: deep learning, random forest, and support vector machine classification algorithms
ABSTRACT The use of computer image analysis can assist the extraction of morphological information from seeds, potentially serving as a resource for solving taxonomic problems that require extensive training by specialists whose primary method of examination is visual identification. We propose to test the ability of deep learning, SVM and random forest algo

5. ARTIFICIAL NEURAL NETWORK-BASED METHOD TO IDENTIFY FIVE VARIETIES OF EGYPTIAN FABA BEAN ACCORDING TO SEED MORPHOLOGICAL FEATURES
ABSTRACT One of the new crop varieties that have been adopted for high yield is the Egyptian faba bean. However, poor-quality faba bean has reduced economic value. Quality evaluation is thus important and can be performed using computational intelligence. We developed a robust method based on morphological features and artificial neural network for quality g

6. Isolation, identification and characterization of endophytic fungi of Bambusa oldhamii munro applied as antagonists to Pyricularia oryzae
ABSTRACT Endophytic fungi, in addition to improving plant development, may produce antimicrobial substances that can inhibit pathogens. The objective of this study was to isolate and characterize endophytic fungi of Bambusa oldhamii and evaluate in vitro antagonism to Pyricularia oryzae. Fungal isolates of B. oldhamii shoots were purified and identified by n

7. Scolytinae species damaging Carya illinoinensis trees in southern Brazil
ABSTRACT This study aims to report two species of Scolytinae that have been damaging Carya illinoinensis trees in southern Brazil. In two Brazilian municipalities, Guarapuava in Paraná State and Pantano Grande in the Rio Grande do Sul State, insects of the Scolytinae family were found damaging pecan trees. Infested tree samples were kept in the laboratory i

8. Áreas restauradas revelam nova ocorrência de Neofavolus subpurpurascens (Murrill) Palacio & Robledo (Basidiomycota, Polyporaceae) para o Estado de São Paulo, Brasil
RESUMO A diversidade de Agaricomycetes lignícolas (Basidiomycota) foi estudada no Parque Florestal São Marcelo, localizado no município de Mogi-Guaçu, SP, Brasil, em processo de restauração desde 2002 por meio de um plantio com mais de 100 espécies arbóreas nativas. As coletas foram realizadas bimestralmente durante o período de outubro de 2015 a ou

9. Caracteres importantes na identificação de espécies de Ludwigia (Onagraceae) ocorrentes no Recôncavo da Bahia, Brasil
Resumo Na flora aquática do Brasil, o gênero Ludwigia apresenta ca. 48 espécies. A maioria das espécies de Ludwigia é anfíbia, apresentando uma grande plasticidade fenotípica, o que torna sua identificação complexa. O objetivo deste trabalho foi realizar um levantamento taxonômico e analisar caracteres diagnósticos na delimitação das espécies d

11. Range distribution and contributions to taxonomy of Elops smithi (ELOPIFORMES: ELOPIDAE)
Abstract: This study presents the first record of Elops smithi for northern Brazil. The evidence suggests this species is being misidentified incorrectly as Elops saurus in estuaries of the Western Atlantic Ocean. Here, morphological, molecular, and cytogenetic evidence identified all ladyfish specimens from one estuary in the region as E. smithi. Thus, at l

12. Increasing the digital repository of DNA barcoding sequences of sand flies (Psychodidae: Phlebotominae)
Sand fly identification is complex because it depends on the expertise of the taxonomist. The females show subtle morphological differences and the occurrence of the species complexes are usual in this taxon. Therefore, a fragment of the cytochrome c oxidase subunit I (COI) gene is used for taxon barcoding to resolve this kind of problem. This study incorpor
