1. CHEMICAL AND ENERGETIC CHARACTERISTICS OF AFRICAN SWEET SORGHUM AS A SOURCE OF BIOENERGY
ABSTRACT The aim of this study was to evaluate the energetic potential achieved by the application of phyto-regulators to sweet sorghum cultivars. A randomized complete block design was used. Experiments were conducted using two sweet sorghum cultivars (BRS 508 and BRS 509), fourphyto-regulators (ethephon, ethyl-trinexapac, glyphosate, and sulfometuron-methy

2. Arbuscular mycorrhizal fungi and auxin associated with microelements in the development of cuttings of Varronia leucocephala
RESUMO Varronia leucocephala é uma planta utilizada pela população para fins terapêuticos. Um dos maiores problemas para produção de mudas dessa espécie é o baixo percentual de enraizamento. Objetivou-se estabelecer um protocolo de enraizamento de estacas de V. leucocephala utilizando fitorreguladores e microelementos associados com fungos micorrízi

3. 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

4. INFLUENCIA DEL USO DE REGULADORES DE CRECIMIENTO SOBRE BROTES VEGETATIVOS Y NÚMERO DE ESTRÓBILOS MASCULINOS EN Pinus pinea L. EN CHILE
ABSTRACT The use of growth regulators or phytoregulators, is an alternative to increase flowering in the Pinaceae family. In this study, we examined the effects of the application of growth regulators (plant growth regulators) on vegetative shoots and male strobili of Pinus pinea L. Selected phytohormones were gibberellic acid (GA4/7), naphthalenacetic acid

5. Indução de brotação apical em mudas provenientes de sementes e do enraizamento de estacas de mangostãozeiro.
Com objetivo de induzir a brotação apical de mudas de mangostãozeiro, foi realizado um experimento que consistiu na aplicação de dois reguladores de crescimento: cinetina (0, 100 e 400 mg L-1) e giberelina (50 mg L-1), e outros dois experimentos para obtenção de estacas enraizadas: a) aplicação de ácido-indol-3-butírico nas concentrações de 0, 1

7. IN VITRO REGENERATION OF Parapiptadenia rigida (Bentham) Brenan / REGENERAÇÃO IN VITRO DE Parapiptadenia rigida (Bentham) Brenan
The Parapiptadenia rigida (Bentham) Brenan is a native forest specie that can be used in the restoration of gallery forests and degraded areas. This work has the objective to develop the regeneration in vitro of P. rigida using explants of aseptic seedlings. In experiment 1, seeds of P. rigida were disinfected in 0.0, 2.5 and 5.0% of sodium hypochlorite duri

8. 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

9. In vitro behaviour of explants from potassium treated carrot matrixes (daucus carota l.). / Comportamento in vitro de explantes de matrizes de cenoura (Daucus carota L.) tratadas com variáveis níveis de potássio.
The growth of plants, organs, tissues and cells in vitro culture depends on the development of optimized culture medium for the perfect interaction among essential components such as phytoregulators, carbon source and minerals nutrients. The factors limiting the growth of organs or tissues in vitro conditions are similar to those limiting growth in vivo cond
