13. Morpho-physiological changes in Billbergia zebrina due to the use of silicates in vitro
Abstract The use of silicon in Billbergia zebrina cultivation in vitro is an alternative for optimizing micropropagation of this important ornamental plant species. The objective of the present study was to evaluate the growth and anatomical and physiological alterations in Billbergia zebrina (Herbert) Lindley plants as a function of different sources and co

14. Impact of Nitrate and Ammonium ratio on Nutrition and Growth of two Epiphytic Orchids
Abstract Phalaenopsis and Dendrobium do not grow and flower well with 100% ammonium (NH4-N); and there are detailed studies on the effects of nitrate (NO3-N) and ammonium ratios on the flowering, but no information about accumulation of other nutrients and the effects of ammonium toxicity on orchids. For this reason, two experiments were carried out with orc

15. Propagación del banano: técnicas tradicionales, nuevas tecnologías e innovaciones
Abstract The different propagation systems for the banana: conventional or by tissue culture are reviewed. Conventional propagation, mainly using suckers, whole rhizomes or bits are still in use for familiar plantings or in farms for local markets in many tropical countries, while vitroplants are the rule in modern commercial banana cultivation. After exami

16. Bioprospecting and selection of growth-promoting bacteria for Cymbidium sp. orchids
ABSTRACT: Inoculants containing bacteria which promote growth in plants can increase productivity and both the economic and the environmental cost in plant crop systems. Similarly, in the flower and ornamental plant sector, the use of diazotrophic bacteria is a promising approach for improving orchid propagation from tissue culture to the ex vitro environmen

17. Slow-grown in vitro conservation of Heliconia champneiana cv. Splash under different light spectra
ABSTRACT: In vitro techniques, with the purpose of conserving the genetic resources of plants, are fundamental to the feasibility of establishing germplasm banks and enabling the commercial production of micropropagated plants. The aim of this study was to evaluate the use of different spectra of light in in vitro germplasm conservation by slow grown storage

18. Differential survivorship of congeneric ornamental fishes under forecasted climate changes are related to anaerobic potential
Abstract Two Amazonian closely related tetras – cardinal Paracheirodon axelrodi and green neon P. simulans – were artificially acclimatized to environmental chambers mimicking future climate change scenarios (mild, moderate and extreme), using a microcosm facility. P. simulans survived (100%) to all scenarios after 30 days exposure, while P. axelrodi pre

19. TECHNICAL FEASIBILITY OF THE ACCLIMATIZATION SYSTEM IN AVIARY OF POSTURE: A CASE STUDY
ABSTRACT: The objective of this study was to compare the performance of laying hens between automated aviaries, one with and another without acclimatized system. On a daily basis it was registered in each aviary the mortality, the egg production, and the feed consumption. The variables of the dry bulb temperature, relative humidity and black globe temperatur

20. Micropropagation of Cyrtopodium paludicolum (Orchidaceae) from root tip explants
Abstract An efficient protocol for in vitro plant propagation of Cyrtopodium paludicolum has been developed using root tips dissected from well-developed seedlings. Root tips were cultured on Knudson medium supplemented with α-naphthaleneacetic acid (NAA), and/or thidiazuron (TDZ). TDZ did not induce protocorm-like bodies (PLBs) in the NAA absence, indicati

21. In Vitro Mid-Term Conservation of Acorus calamus L. via Cold Storage of Encapsulated Microrhizome
ABSTRACT In vitro rhizome production, encapsulation and cold storage of Acorus calamus were attempted for its propagation and ‘true-to-type’ conservation. Shoot cultures were initiated using underground rhizome buds, on 6-benzyladenine (BA) containing Murashige and Skoog (MS) medium. Maximum microrhizome production was observed in presence of 33.3 µM BA

22. Efficient and new method for Tectona grandis in vitro regeneration
Abstract The aim of this study was to develop a shoot regeneration protocol for Tectona grandis by examining the effects of pretreatments, regeneration culture medium, adventitious rooting, and acclimatization. The best organogenic potential was achieved when hypocotyls and cotyledonary segments from seedlings germinated on a medium containing TDZ, were cult

23. Effect of phosphorus on arsenic uptake and metabolism in rice cultivars differing in phosphorus use efficiency and response
ABSTRACT A hydroponic experiment was carried out to investigate the effect of phosphorus (P) nutrition on arsenic (As) uptake and translocation within the seedlings of rice cultivars. The experiment occurred in three stages: I 5 days of acclimatization (nutritive solution); II 10 days under P (0.0 and 0.09 mM) and As (0.0 and 100 mM) treatments; III 5 days u

24. INFLUENCE OF THE APPLIED ORGANIC LOAD (OLR) ON TEXTILE WASTEWATER TREATMENT USING SUBMERGED ANAEROBIC MEMBRANE BIOREACTORS (SAMBR) IN THE PRESENCE OF REDOX MEDIATOR AND POWDERED ACTIVATED CARBON (PAC)
Abstract This paper evaluated the treatment of textile wastewater in submerged anaerobic membrane bioreactors (SAMBR) operated on a bench scale. Particularly, the influence of operational conditions, such as the applied organic rate (OLR) and the dilution factor (for toxicity attenuation) of the textile wastewater, was evaluated on color and organic matter r
