1. Adventitious rooting of cultivars and clonal selections of Prunus spp. rootstock under intermittent mist system
ABSTRACT To reduce peach tree losses due the Peach Tree Short Life (PTSL), the main research line in Brazil is to select tolerant rootstock and perpetuate it by cloning methods. The objective was to evaluate adventitious rooting capacity of softwood cuttings of three cultivars and several clonal rootstock selections of Prunus spp., under intermittent mist s

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. 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

4. VEGETATIVE PROPAGATION OF Cordia trichotoma (VELL.) ARRAB. EX STEUD. BY CUTTINGS FROM SHOOTS AND ROOTS
ABSTRACT Cordia (Cordia trichotoma (Vell.) Arrab. ex Steud.) is a native species that has high quality wood and potential for the establishment of commercial plantations. However, its propagation by seeds is difficult, and vegetative propagation is a good alternative. The aim of this study was to evaluate the vegetative propagation of cordia by cuttings from

5. GERMINATION POTENTIAL AND VEGETATIVE PROPAGATION OF Aegiphila brachiata VELL
ABSTRACT The objective of this study was to evaluate the germination potential of Aegiphila brachiata (peloteiro) and its propagation through stem-cuttings, as well as how the age of parental plants and the application indolebutyric acid (IBA) and inoculant of Azospirillum brasilense influence adventitious rooting of the species. Thus, the physical character

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. MINI-CUTTING TECHNIQUE FOR VEGETATIVE PROPAGATION OF Paratecoma peroba
ABSTRACT Paratecoma peroba is a native Brazilian forest species of great economic and ecological interest, which is currently at risk of extinction owing to excessive wood exploration. The use of the mini-cutting technique could facilitate the vegetatively propagation of this species. The objective of the present study was to establish a vegetative propagati

9. Propagação de jamboleiro [Syzygium cumini (L.) Skeels] por alporquia
Resumo O jamboleiro propaga-se geralmente por sementes, sendo este método inviável, devido aos problemas de segregação genética e pelo longo período que as plantas levam para alcançar a idade reprodutiva. Desta forma, o desenvolvimento de protocolo para propagação vegetativa desta espécie por meio da alporquia se torna alternativa importante a ser

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. Advances observed in papaya tree propagation
Resumo O mamoeiro (Carica papaya L.) é uma fruteira de bastante interesse econômico e alimentar em todo o mundo. Sua propagação pode ocorrer tanto por via sexuada como assexuada. Tradicionalmente é propagado por sementes, entretanto, a propagação vegetativa vem sendo frequentemente utilizada com o uso de técnicas de cultura in vitro e ex vitro. Na p

12. Growth and Development of Sourgrass Plants from Vegetative Parts of Clumps
RESUMO: O capim-amargoso (Digitaria insularis) é uma planta perene com elevado potencial de infestação, possui desenvolvimento rápido e agressivo e se reproduz tanto por sementes quanto por rizomas. A infestação de D. insularis tem aumentado nas áreas agrícolas onde não há culturas de cobertura estabelecidas na entressafra. Nessas áreas, vem se to
