13. IN VITRO AND EX VITRO PROPAGATION OF MATE (Ilex paraguariensis Saint Hilaire Aquifoliaceae). / PROPAGAÇÃO IN VITRO E EX VITRO de erva-mate (Ilex paraguariensis Saint Hilaire Aquifoliaceae).
Mate (Ilex paraguariensis) is an important species in Southern Brazil for its economical and cultural values. The present work had the objectives of analyzing the propagation of mate by cuttings, disinfection and in vitro establishment of nodal segments from adult plants and micropropagation of plants originated from immature embryos. Mate cutting were submi

14. Stressful factors in seed germination and in vitro propagation of Passiflora edulis Sims f. flavicarpa Degener / Fatores de estresse na germinação de sementes e na propagação in vitro de Passiflora edulis Sims f. flavicarpa Degener
The oxidative stress results into reaction series of the reactive oxygen species (ROS) that are considered as detrimental to biological membranes. In addition, the tissues can produce and liberate gases such as the ethylene and CO2, as being the first one responsible for the chlorosis, senescence and leaf abscission. High irradiance on the photosynthesizing

15. Light and sucrose in micropropagation of Cattleya walkeriana: Anatomic and Physiologic changes / Luz e sacarose na microporapgação de Cattleya walkeriana: alteraçõies anatômicas e fisiológicas
Cattleya walkeriana ia a orchid of great decorative value. The use of micropropagation techniques are important issues in the reproduction of that specie. The use of conventional techniques of micropropagation causes plantlet losses during the acclimatization process and also promotes a high energy consumption in growth rooms which finishes by increasing the

16. Effects of Cryogenic Treatment on Plantlet Production from Frozen and Unfrozen Date Palm Callus
Embryogenic date palm (Phoenix dactylifera L. var. Medjool) callus cultures were treated with a cryoprotective mixture of polyethylene glycol (Carbowax 6000), glucose, and dimethylsulfoxide (10%/8%/10%, w/v); treated with the mixture, frozen to −196°C, and then thawed; or left untreated. Growth subsequent to treatment was measured as fresh weight increase
