Physical quality of seeds of Moquiniastrum polymorphum

Braz. j. biol; 79 (1), 2019
Abstract This study aimed to analyze the physical properties of the seeds of Moquiniastrum polymorphum when processed by mini-SAS, X-ray and seed blower systems. The seeds were purchased from Seeds Caiçara, located in Penápolis-SP. After purchase, the seed lot was characterized by standard tests. In th...

Effects of methanolic extract of Brassica juncea seeds on biochemical parameters and histological integrity of the heart and liver of albino rats

Int. j. morphol; 37 (1), 2019
SUMMARY: Brassica juncea (Indian mustard) seeds are consumed in treatment of high blood pressure, headache and prevention of heart disease. The aim of the present study was to investigate the effects of methanol extract of Brassica juncea seeds [BJME] on the heart and liver of adult Albino Wistar rats. A...

Influence of Silver Nitrate on Somatic Embryogenesis Induction in Arabica Coffee (Coffea arabica L)

Abstract The influence of silver nitrate (AgNO3), benzyladenine (BAP), and indole-3-acetic acid (IAA) on low frequency somatic embryogenesis (LFSE) induction in Caturra and Catuaí arabica coffee was evaluated. For the Caturra cultivar, the production of somatic embryos was significantly increased by add...

Evaluation of the biological quality of defatted pequi (Caryocar brasiliense Cambess) seed flour protein supplemented with lysine to rats (Rattus norvegicus)

Rev. Nutr. (Online); 32 (), 2019
ABSTRACT Objective In the biome of the Brazilian Cerrado, there are a lot of fruit tree species that stand out for their sensory quality and for presenting potentialities in the market of pulp and almond. Among these species, the pequi deserves attention because it has an almond rich in proteins and tha...

Effect of seed treatment with insecticides on the control of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in soybean

Arq. Inst. Biol; 86 (), 2019
Fall armyworm is one of the main insect pests in Brazil. Thus, the present work aimed to evaluate the seed treatment effect on the control of Spodoptera frugiperda in initial infestations of soybean crops. The experimental design was completely randomized with four replicates of six insecticide treatment...

Sanitary and physiological quality of ‘purple’ corn (Zea mays L. ) seeds submitted to thermotherapy

Arq. Inst. Biol; 86 (), 2019
The use of seeds with good sanitary and physiological potential ensures the establishment of the crop, with a uniform, vigorous and disease-free seedling stand, which will result in good productivity levels. Seen that, the objective was to evaluate the sanitary and physiological quality of purple corn se...

Influence of physiological and health quality on the vigor of cucumber seeds

Arq. Inst. Biol; 86 (), 2019
The physiological performance of seeds is related to their physiological quality and seed vigor, while their health quality may interfere with germination and early seedling establishment in the field due to the interaction of microorganisms associated with seeds. The study aimed to evaluate the physiolo...

Potential of natural repellents methylanthranilate and anthraquinone applied on maize seeds and seedlings against house sparrow (Passer domesticus) in captivity
