“…A high-water content favors seed deterioration. The variation in the occurrence of moisture deterioration is mainly due to variations in the characteristic pluviometric indexes of each month (Bornhofen et al, 2015). In this work, the environmental conditions which prevailing at the harvest time were favorable to the maintenance of a low grain water content in all treatments, which eliminates the possibility of deterioration and favors the maintenance of seed quality.…”

“…In a paper on the physiological quality of soybean seeds of Silva, Lazarini and Sá (2007), both anticipation and delay in the sowing date were detrimental to obtaining seeds with higher physiological quality because the seeds did not tolerate temperature stress and high relative humidity demonstrated by the aging test. For the western region of Santa Catarina Stage, Brazil, sowing in the middle of December (15/12) is recommended for the production of soybean seeds with high vigor (Bornhofen et al, 2015).…”

Variations in the sowing date of chia (Salvia hispanica L.) reflect directly on the physiological potential of the produced seeds. This study aimed to analyze the yield and the physical and physiological quality of seeds from the main stem and branches of Salvia hispanica plants grown at different sowing dates. A field experiment was conducted in the crop year of 2016/2017 in five sowing dates (16/09/22, 16/10/28, 17/01/03, 17/02/08 and 17/03/24) in a randomized complete block design with four replicates. Harvest at each sowing date was done when 80% of the leaves of each plant exhibited a darker color, indicating that they were dry. Seed yield was determined in each plant compartment (main stem and branches) and final ear length (cm) and diameter (cm) were also measured at all sowing dates. The following physical and physiological tests were performed to determine seed quality: water content, mass of one thousand seeds, germination test, first count germination, length (root and hypocotyl) and dry matter of the seedlings. Chia can be sown from September to February providing seed yield with high physical and physiological quality. The physical and physiological quality of the chia seeds does not differ between main stem and branches. In late sowing, there is the risk of frost occurrence what may impair the physiological quality and the yield of chia seeds. The best sowing month for obtaining higher yield of chia seeds in a south subtropical region is January.

Aryl removal methods and passion fruit seed positions: Germination and emergence

et al. 2015

-Yellow passion fruit has conquered a significant position in the agribusiness of tropical fruits; therefore, farmers have been interested in expanding their groves, and technical information that guarantees the high yield of the farmings is needed. Aiming to observe factors related to the propagative material targeted at quality and maximization of the genetic potential, the objective of the study consisted in assessing germination and emergence of passion fruit seeds collected in three positions in the fruits and submitted to different methods of mucilage removal (aryl). The passion fruits were split in three parts: distal, medial and proximal and the contents of each part was divided in two. The content of each part of the fruit was submitted to mechanical and by fermentation methods for removal of aryl. It is concluded that the seed position in the fruit does not interferes with the germination. The aryl removal method by mechanical extraction affects the germination and seedling emergence.Index terms: Passiflora edulis, mechanical extraction, fermentation, propagation, mucilage. Métodos de remoção do arilo e posições das sementes no fruto de maracujá:Germinação e emergência RESUMO -O maracujá-amarelo conquistou significativa posição no agronegócio de frutas tropicais, com isso, produtores despertaram interesse para expandir seus pomares, sendo necessárias informações técnicas que garantam a alta produtividade das lavouras. No intuito de observar fatores relacionados ao material propagativo visando a qualidade e a maximização do potencial genético objetivou-se avaliar a germinação e a emergência de sementes de maracujá coletadas em três posições nos frutos e submetidas a métodos de retirada da mucilagem (arilo). Os frutos de maracujá foram seccionados em três partes: distal, mediana e proximal. Cada um destes conteúdos foi submetido aos métodos mecânico e de fermentação para remoção do arilo. Podendo concluir que a posição da semente no fruto do maracujazeiro não interfere na germinação e o método de remoção do arilo por extração mecânica prejudica a germinação e a emergência de plântulas.Termos para indexação: Passiflora edulis, extração mecânica, fermentação, propagação, mucilagem.

“…For production of high quality seeds, the effects of genotype are a determinant factor. However, the effects caused by the cultivation environment and the interaction between genotype and environment are pronounced (Bornhofen et al, 2015). Thus, it is of great importance to study the interaction between the genotype and the cultivation environment, evidencing probable effects on the physiological quality of the seeds produced.…”

Plant growth and physiological quality of quinoa (Chenopodium quinoa Willd) seeds grown in Southern Rio Grande do Sul, Brazil

et al. 2019

Quinoa (Chenopodium quinoa Willd) an annual grain crop belonging to the Amaranthacea family is the only vegetable food that contains all essential amino acids, micronutrients and vitamins. The study aimed to evaluate the performance, growth and seed physiological quality of two genotypes of quinoa in Southern Rio Grande do Sul region. The cultivar BRS Piabiru and one breeding line were grown at green house. The design was completely randomized with four replications and five harvest times during the vegetative stage of the crop. The variables were shoot length, number of leaves, leaf area index, dry matter of aerial parts, dry matter of root and total dry matter of plant. It was concluded that the line and BRS Piabiru have slow initial growth in the first 30 days and strong growth up to 120 days. The breeding line and commercial cultivar showed the same potential for seed production in the temperate climate of this region.
