1. Agronomic trait selection and pre-germinative treatments in passion fruit hybrid
ABSTRACT Seed biometry and dormancy overcoming methods should be considered in the passion fruit production chain, in the seedling production stage, because of the different characteristics that condition the seedlings. The objective of this work was to identify and correlate the main biometric characteristics between seeds and seedlings and to select the be

2. Performance of wheat varieties grown from seeds with different vigor levels
ABSTRACT The objective of this study was to evaluate the performance of wheat plant grown from seeds with different vigor levels. The experimental design was randomized blocks in a 3 x 3 factorial design (cultivar x vigor level) with four replications. The wheat cultivars were Tbio Toruk, Tbio Mestre and Tbio Iguaçu. The classification of vigor levels was

3. Quality of sunflower seeds in function of thickness classification and sowing under speed variation of the seeder-fertilizer
ABSTRACT The objective was to evaluate the quality of sunflower seeds classified according to their thickness and passed through the seeder-fertilizer dosing system under variation of the travel speed. A lot of M734 was classified by thickness passing the seeds through a set of oblong-hole sieves and two thicknesses were selected. A portion of the seeds with

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. Physiological potential of soybean seeds and its relationshipto electrical conductivity
Resumo: O teste de condutividade elétrica (CE) é capaz de detectar a deterioração de sementes ainda em sua fase inicial, tendo em vista que está relacionado com a desorganização das membranas celulares. Deste modo, o presente trabalho teve por objetivo o estudo da utilização do teste de CE como alternativa para avaliação de vigor de sementes de so

8. MICROMORPHOLOGICAL OBSERVATION OF EUCALYPTUS SEEDS, MULTIVARIATE STATISTICAL ANALYSES AND MODELING OF THEIR GERMINATION UNDER SALT STRESS AND OSMOTIC CONSTRAINT
ABSTRACT Micromorphological characters including surface, length and width of seeds were recorded for 19 species of Eucalyptus (Myrtaceae) using stereomicroscope to determine the importance of seed morphological characters as an additional tool for identification.With the aim of selecting and valorizing abiotic-stress-tolerant species with landscape and indu

9. Physiological potential and health of soybean seeds obtained from organic and conventional systems
Resumo: A qualidade da semente produzida é o reflexo do manejo empregado e das condições ambientais durante o cultivo. Objetivou-se avaliar o potencial fisiológico e a sanidade de sementes de soja produzidas em sistema orgânico e convencional. Foram testados os genótipos UEL 110 e 122, BRS 257 e 284, nos manejos orgânico e convencional em delineamento

10. Scanning Electron Microscopy and Crystallinity of starches granules from cowpea, black and carioca beans in raw and cooked forms
Abstract Beans are a vital food for the population around the world because it contains a relatively high amount of protein, vitamins, fiber, and minerals, being an important vegetable source of iron, particularly when combined with ascorbic acid and cysteine. The starch content in the seed is between 45 and 60%. This paper evaluated the granular structure o

12. Seed size affects productive parameters in Sudan grass
RESUMO: O emprego de sementes maiores pode melhorar o desenvolvimento inicial, o estande de plantas e a produtividade de massa em cultivos forrageiros. Este trabalho visou avaliar o efeito do tamanho da semente de capim sudão (Sorghum sudanense L.), padronizada quanto à densidade, sobre parâmetros da qualidade fisiológica e de produtividade da cultura.
