1. Ethephon as a potential tool to manage alternate bearing of ‘Fuji’ apple trees
ABSTRACT The objective of this study was to investigate the effect of different rates of ethephon on return bloom and yield, and fruit quality of ‘Fuji’ apple trees. The experiment was performed during the 2014/2015 and 2015/2016 growing seasons. Eighteen-year-old Fuji Standard apple trees grafted on M.9 were sprayed with different rates of ethephon (300

2. Mini-cutting rooting and plantlet growth in Erythrina crista-galli L.
ABSTRACT In this study, we evaluated the adventitious rooting competence of mini-cuttings and plantlet growth of two clones of swamp cork (Erythrina crista-galli L.). Experiments were carried out in a factorial of two clones to study the need of application of indolebutyric acid (IBA), substrate composition for mini-cutting rooting and plantlet growth, and r

3. 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

4. Early induction of orthotropic shoots in Coffea canephora
ABSTRACT In Coffea canephora, the number of orthotropic shoots is directly related to plant yield. The objective of this study was to evaluate the vegetative and yield performance of Coffea canephora, from the botanical variety Conilon, under different management systems for early emission of orthotropic shoots. The experiment was carried out in Ouro Preto d

5. 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

6. VITRO OF Melanoxylon brauna SCHOTT. MORPHOGENESIS: RESPONSIVENESS OF EXPLANTS TO PERMANENT AND TEMPORARY IMMERSION GROWTH REGULATORS
ABSTRACT Melanoxylon brauna is propagated by seeds, however, low yield, pest attack and short viability are problems in seedling production. In vitro cultivation is an alternative for large-scale seedling production, but studies with this species are scarce. The aim of the work was to analyze the in vitro morphogenesis of braúna. Explants after induction of

7. Sucrose concentration and volume of liquid medium on the in vitro growth and development of blackberry cv. Tupy in temporary immersion systems
RESUMO O uso de micropropagação de pequenos frutos como a amoreira-preta tem sido empregado devido à necessidade de obtenção de plantas com alta qualidade fitossanitária. A tecnologia de biorreatores tem sido usada para melhorar a eficiência na produção de mudas. Assim, o objetivo deste trabalho foi avaliar a melhor quantidade de meio de cultura e a

8. 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

9. A new cecidogenous species of many-plumed moth (Alucitidae) associated with Cordiera A. Rich. ex DC. (Rubiaceae) in the Brazilian Cerrado
ABSTRACT Larvae of many-plumed moths (Alucitidae), especially in the world-wide genus Alucita Linnaeus, 1758 are known as borers or gall-inducers on flowers, fruits and shoots of a few dicotyledonous families, including Bignoniaceae, Caprifoliaceae and Rubiaceae. However, there is no study available on the biology of the monotypic, Neotropical genus Prymnoto

10. Micropropagation of Guadua chacoensis (Rojas) Londoño & P. M. Peterson1
RESUMO A cadeia produtiva de bambu, no Brasil, ainda é incipiente, e tem baixa oferta de mudas devido aos métodos convencionais de propagação. Objetivou-se, aqui, estabelecer um protocolo de micropropagação para Guadua chacoensis. Explantes de matrizes cultivadas em ambiente controlado resultaram em menor contaminação, relativamente aos de plantas cu

11. In Vitro Organogenesis from Root Explants of Passiflora miniata Mast., an Amazonian Species with Ornamental Potential
ABSTRACT The present study reports a shoot organogenesis-based system for in vitro regeneration of Passiflora miniata, an Amazonia passion fruit species. Root segments were cultured in Murashige and Skoog (MS) medium supplemented with different concentrations (range 2-9 µM) of 6-benzyladenine (BA); thidiazuron (TDZ) or kinetin (KIN).
