1. Growth of pitaya seedlings according to the type of substrate and the frequency of irrigation
ABSTRACT The objective of this study was to evaluate the development of pitaya cuttings in different substrates under different frequencies of irrigation. The experiment was conducted from January to May 2017 in a greenhouse at Universidade Federal Rural da Amazônia, Capitao Poço, Pará, Brazil. A completely randomized 3 × 7 factorial design with four rep

2. MINI-CUTTINGS TECHNIQUE FOR VEGETATIVE PROPAGATION OF Dalbergia nigra
ABSTRACT The usual propagation method for Dalbergia nigra is via seedings; however, the seasonal supply has a variable quantity of seeds which limits the continuous production of seedlings. Therefore, the objective of this study was to establish a vegetative propagation protocol via mini-cuttings technique for D. nigra from juvenile shoots obtained from seed

3. Exogenous gibberellin and cytokinin in a novel system for in vitro germination and development of African iris (Dietes bicolor)
ABSTRACT The availability of reliable and reproducible micropropagation systems is a decisive step to successfully propagate plant species with slow growth and low germination rate. The effect was investigated of gibberellin (GA) and cytokinin (CK) in the in vitro germination and development of Dietes bicolor (Steud.) Sweet ex Klatt. Seeds were inoculated in

4. GROWTH AND PHYSIOLOGICAL RESPONSES OF YERBA MATE SEEDLINGS AND MINI-CUTTINGS UNDER DROUGHT STRESS
ABSTRACT Yerba mate is a tree species whose natural distribution occurs in the countries of Argentina, Paraguay, and Brazil, where most of the plantations are concentrated. For the establishment of plantations seedlings are commonly used. But alternatively, there are ex vitro vegetative propagation techniques like mini-cuttings technology, which has the pote

5. Determination of the grapevine virome by high-throughput sequencing and grapevine viruses detection in Serra Gaúcha, Brazil
ABSTRACT Among grapevine (Vitis spp.) pathogens, viruses stand out, considering that this fruit plant is broadly susceptible to them and that they cause several diseases, reducing quality and yield of grape production. However, detecting and identifying viral infections in grapevines can be challenging. The objectives of this study were to detect grapevine v

6. Evaluation yield and genetically factors in different cultivars of gladiolus
Abstract In order to suggest the best cultivars of gladiolus to grow in moderate regions of Iran, an experiment was carried out in a complete randomized block design in three replications with five cultivars of Gladiolus grandiflorus (‘Oscar’, ‘Red Advance’, ‘White Prosperity’, ‘Rose Supreme’ and ‘Lemon Drop’) at the ornamental plants res

7. Scientific novel: Araucaria angustifolia branch may be converted into orthotropic trunk by grafting
ABSTRACT Grafting technique has been presented as an alternative for Araucaria angustifolia propagation. However, vegetative rescuing mature trees and obtaining large numbers of propagules is difficult, because the use of branch grafts has not been indicated due to its plagiotropic and morphogenic characteristic, generally resulting in undesired growth of th

8. Physalis angulata L. propagation in vitro
ABSTRACT Physalis angulata L. is a plant with great fruit production potential, mainly in family farms, due to its versatility and valuable products such as jellies and juice concentrates. The aim of the present study is to evaluate the effect of two cytokines - i.e., plant growth regulators 6- benzylaminopurine (BAP) and kinetin (KIN) -, in association, or

9. Interference of aqueous and ethanolic solutions of Adiantum latifolium Lam. (Pteridaceae) leaves on in vitro Ceratocystis cacaofunesta mycelial growth
RESUMO A espécie Ceratocystis cacaofunesta é o agente etiológico do mal-do-facão, patogenia caracterizada por danos irreversíveis no sistema vascular da planta. O controle da doença é difícil e a busca por soluções alternativas e econômicas é necessária. Sabe-se que os compostos das plantas medicinais possuem atividade microbiana e podem ser uma

10. Exigência nutricional e produtividade em minijardim clonal de Toona ciliata var. australis
Resumo O estado nutricional da planta-matriz é imprescindível para a manutenção do seu vigor vegetativo, fundamental para a produção de miniestacas. Portanto, o fornecimento de nutrientes em quantidades ideais durante o manejo das minicepas influencia o sucesso da propagação. Objetivou-se com este estudo avaliar e comparar a produtividade do minijard

11. A Rapid and Reliable Method for Molecular Detection of Fusarium guttiforme, the Etiological Agent of Pineapple Fusariosis
Abstract Pineapple (Ananas comosus var. comosus) fusariosis is an economically important fungal disease affecting the plant and its fruit. A rapid and reliable diagnosis is the base of integrated disease management practices. Fusariosis has resulted in quarantines for pineapple products in Central America, Africa and Asia. Difficulties diagnosing and correc

12. Morphological characterization and selection of castor bean accessions for mechanized production1
RESUMO A mamoneira (Ricinus communis L.) é uma oleaginosa encontrada em várias regiões do mundo, devido à sua fácil propagação e adaptação. O cultivo de genótipos mais produtivos, resistentes a doenças e que permitem o uso de mecanização traz maior retorno econômico para os produtores. Objetivou-se realizar a caracterização morfológica e sel
