Sistema e método de cultura de plantas in vitro para análise de metabolitos lib...
Castro, Mário Rui da Costa Basílio e; Ragonezi Gomes Lopes, Carla Aparecida; Oliveira, Paulo Guilherme de; Zavattieri, Maria AmelyO presente invento diz respeito ao desenvolvimento de um sistema e método de cultura in vitro (1,2) constituído por duas fases, uma sólida (3,4,5) e uma líquida (6), a primeira para suporte da planta (7,8) e a segunda para permitir a análise do meio circundante das raízes (9). Este sistema foi desenhado para permitir uma fácil extracção dos compostos metabólicos libertados/difundidos na fase líquida durante o c...
Micropropagation of Juniperus navicularis, an endemic and rare species from Por...
Castro, Mário Rui; Belo, Anabela; Afonso, Anabela; Zavattieri, Maria AmelyJuniperus navicularis Gand (= J. oxycedrus L. subsp. transtagana Franco) is an endemic dioecious shrub from the Plio-Plistocene transition sands of the west Portuguese coast line. It grows in sole or mixed stands along with Pinus pinea and P. pinaster and, more rarely, with Quercus lusitanica. In order to reduce fire incidence in these Mediterranean mixed stands, forest management practices of mechanical or che...
Finite Element Analysis (FEA) applied to heat transfer optimization process of ...
Silva, Francisco J. G.; Ferreira, F.; Costa, C.; Castro, Ana Cristina Meira; Meixedo, João Paulo; Castro, Mário Rui Alvim de; Santos, R. P. C.The aim of this study is to optimize the heat flow through the pultrusion die assembly system on the manufacturing process of a specific glass-fiber reinforced polymer (GFRP) pultrusion profile. The control of heat flow and its distribution through whole die assembly system is of vital importance in optimizing the actual GFRP pultrusion process. Through mathematical modeling of heating-die process, by means of ...
Adventitious rooting of conifers: influence of physical and chemical factors
Ragonezi, Carla; Klimaszewska, Krystyna; Castro, Mário Rui; Lima, Mónica; Oliveira, Paulo; Zavattieri, Maria AmelyIn conifers, vegetative propagation of superior genotypes is the most direct means for making large genetic gains, because it allows a large proportion of genetic diversity to be captured in a single cycle of selection. There are two aims of vegetative propagation, namely large-scale multiplication of select genotypes and production of large numbers of plants from scarce and costly seed that originates from con...
Influence of light quality and intensity on adventitious root formation in micr...
Ragonezi, Carla; Castro, Mário Rui Basílio; Klimaszewska, Krystyna; Lima, Mónica; Zavattieri, Maria AmelyIn the present study of Pinus pinea L., further improvement of microshoot rooting was achieved by applying Cool-white light at increased intensity from 60 to 90 µmol m-2 s-1. In contrast, light provided by Gro-lux lamps promoted rooting of the microshoots at the same frequency regardless of its intensity. Majority of microshoots (70.4%) grown under Cool-white lamps at the intensity of 90 µmol m-2 s-1 were also ...
Mycorrhiza-like structures in rooted microshoots of Pinus pinea L.
Castro, Mário Rui da Costa Basílio e; Ragonezi Gomes Lopes, Carla Aparecida; Klimaszewska, Krystyna; Lima, Mónica; Oliveira, Paulo Guilherme dePinus pinea L. (stone pine) is one of the major plantation species in Iberian Peninsula, being Portugal the largest edible seed producer in the world. The induction and improvement of in vitro rhizogenesis of microshoots of Pinus pinea was developed in our laboratory using a co-culture system with ECM fungi. In the acclimation phase in mixed substrates, or in rhizotrons, anatomical and morphological studies wer...
