The influence of ultra-high diluted compounds on the growth and the metabolites of Oryza sativa L

Int. j. high dilution res; 19 (1/2), 2020
The ultra-high dilutions (UHDs) have been widely used in the field of human, animal and plant treatment. In the present research, the effects of the potentized ultra-high dilutions (UHDs) on physiological and biochemical variations in Oryza sativaL. (rice) were investigated. Methods: To study the effect ...

Soybean (Glycine max L) seed quality treated with timbó (Magonia pubescens A. St.-Hil) seed coat

Arq. Inst. Biol; 87 (), 2020
The objective of this study was to evaluate the effect of timbó seed coat on the physiological and sanitary quality of soybean seeds. Timbó seeds were collected from mature fruits in the Cerrado. The external layer of the seed coat was removed and crushed in a mill and used in the treatment of soybean ...

Germination constraints of dicarpic cypselae of Bidens pilosa L

Braz. j. biol; 79 (3), 2019
Abstract Bidens pilosa L. is a heterocarpic weed species with two cypselae types that present morpho-physiological differences, being the peripheral type smaller and slower to germinate than the central one. We aimed to verify how the germination mechanism varied between types. We focused on two mechanis...

β-Glucanase Addition in Brewing Malt Produced by Reduced Time of Germination

Abstract The β-Glucans content has straight influence on the quality of malt and beer, mainly during the filtration step. Barley presenting high β-Glucan content demands longer germination time at malting. The application of commercial β-Glucanase is an alternative to accelerate the proces...

Somatic embryogenesis in Carica papaya as affected by auxins and explants, and morphoanatomical-related aspects

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT The aim of this study was to evaluate somatic embryogenesis in juvenile explants of the THB papaya cultivar. Apical shoots and cotyledonary leaves were inoculated in an induction medium composed of different concentrations of 2,4-D (6, 9, 12, 15 and 18 µM) or 4-CPA (19, 22, 25, 28 and 31 µM). ...

Aislados de Bacillus provenientes de la rizósfera de cactus incrementan la germinación y la floración en Mammillaria spp. (Cactaceae)
Bacillus isolates from rhizosphere of cacti improve germination and bloom in Mammillaria spp. (Cactaceae)

Rev. argent. microbiol; 48 (4), 2016
Las cactáceas son la vegetación característica de las zonas áridas en México, donde las lluvias son escasas, la evapotranspiración es elevada y la fertilidad de los suelos es baja. Las plantas han desarrollado estrategias fisiológicas como la asociación con microorganismos en la zona de la rizós...

Phytotoxic potential of young leaves from Blepharocalyx salicifolius (Kunth) O. Berg (Myrtaceae)

Braz. j. biol; 76 (2), 2016
Abstract The loss of leaves by plant species found in the Cerrado (Brazilian savanna) is an energetically expensive process due to adverse environmental conditions and predation by herbivory. The mature leaves have adaptations which minimize these events. However, the young individuals lack these structu...

Extratos de Brunfelsia uniflora na germinação de sementes de Crotalaria spectabilis

As sementes do gênero Crotalaria L., de um modo geral, apresentam dificuldades no processo germinativo. O objetivo da pesquisa foi avaliar a eficiência do extrato bruto de Brunfelsia uniflora na germinação de Crotalaria spectabilis. O delineamento foi inteiramente casualizado, com quatro tratamentos ...
