13. ENRAIZAMIENTO DE VITROPLANTAS DE MEMBRILLO (Cydonia oblonga) POR MEDIO DE INMERSIÓN TEMPORAL AUTOMATIZADA Y SU ACLIMATACIÓN
ABSTRACT Quince (Cydonia oblonga) is a non-traditional fruit tree found in Costa Rica that has therapeutic and nutritional properties; however its slow growth and root formation prevents the production of a homogeneous population when using conventional farming techniques. Hence, the aim of this research project was to generate uniform plant material in a re

14. Root growth and distribution in sugarcane cultivars fertigated by a subsurface drip system
Despite of the agronomic importance for water management, few studies of sugarcane roots have been performed under field conditions during the crop cycle. The aim of this study was to determine the cumulative root density (LA), root distribution on soil profile and the effective rooting depth (ERD) for three sugarcane cultivars using the minirhizotron method

15. An efficient system for in vitro propagation of Bouchea fluminensis (Vell.) Mold. (Verbenaceae)
This study aimed to establish and propagate in vitro plants of Bouchea fluminensis, a medicinal species known in Brazil as gervão-falso ("false verbena"), evaluating the influences of different growth regulators on in vitro multiplication and rooting stages, as well as examining ex vitro acclimatization of rooted plants. Explants were established on Murashi

16. Produção e desenvolvimento da nogueira macadâmia em clima Cwa / Macadamia production and development at the Cwa climate
The macadamia cultivation presents itself as an important alternative for fruit growers of the State of São Paulo, mainly because of its rusticity and the value reached by their fruits. However, studies related to their development and characteristics of production are essential for the correct choice of the variety to be cultivated. In order to characteriz

17. Desenvolvimento e produção de cana-de-açúcar em sistema sob palhada
Due to environmental constraints, lack of manpower and the search for better efficiency, the harvesting of sugar cane tends to be mechanized, causing large amount of straw is available in this new system. There are benefits to soil and culture provided by this residue. However, it was discussed what amount would be sufficient to promote these benefits and wh

18. Efficient Regeneration of Eucalyptus urophylla x Eucalyptus grandis from Stem Segment
The aim of the present study was to establish an efficient regeneration system for the hybrid E. urophylla x E. grandis by means of organogenesis. Stem segments from seedlings were used as explants and cultured in a modified Murashige and Skoog medium (MS), supplemented with 13.2 µM N-phenyl-N'-[6-(2-chlorobenzothiazol)-yl] urea (PBU) and 0.285 µM indole-3

20. Behaviour of pre-parturient sows housed in intensive outdoor or indoor systems.
This work compared the behaviour of pre-parturient sows housed in intensive confined and outdoor systems, during the morning and afternoon prior to delivery. Eight sows were kept individually in farrowing crates or in paddocks with access to fresh pasture from 8 to 10 days before expected parturition. All outdoor sows built a nest within 24 hours before farr

22. Efeito do aib sobre o enraizamento e desenvolvimento de estacas de quivi(actinidia deliciosa) / Effect of iba on the rooting and development of kiwi cuttings (Actinidia deliciosa)
O objetivo do trabalho foi estudar o efeito do ácido 3-indoibiitirico (A/B) no enraizamento e desenvolvimento de estacas semi-lenhosas de quivi, cv. Monte. O experimento foi conduzido na Estação Experimental Agronômica da UFRGS, em Eldorado do Sul, RS, e constou de cinco tratamentos, com cinco repetições, em blocos casualizados. Usou-se 19 sacos/parcel

23. Acúmulo de ricina em sementes de mamona e silenciamento do gene em plantas geneticamente modificadas
Castor bean (Ricinus communis L.) is an oilseed of great economic and social importance. The oil extracted from its seeds is used in biodiesel production and as raw material for chemicals, cosmetics and lubricants. Besides the oil extracted from the seeds, their production chain generates side-products, which can be used as organic fertilizer of good quality

24. Potencial de enraizamento de estacas lenhosas de espÃcies florestais da mata ciliar / Potential for rooting of wood cutting species from riparian forest
The bioengineering has been used for the containment of slopes and ravines on the banks of watercourses. One of its tools is the use of hardwood cuttings planted directly in the field, but this requires that species have local adaptation with large capacity for rooting. Thus, this study had the objective of study the propagation by cuttings of native woody f
