| ABSTRACT The technique of etiolation is widely used in the micropropagation of various plant species. The aim of this study was to evaluate growth and development in shoots of Cattleya labiata grown in vitro, as a function of growth regulators and the presence and absence of light. Stem segments, approximately ± 1.0 cm in height, were inoculated in test tubes containing 15.0 mL of MS culture medium supplemented with different concentrations of BAP (0.0, 2.0 and 4.0 mg L-1) and NAA (0.0, 1.0 and 2.0 mg L-1), and in different growth environments (growth room, darkness and a photoperiod of 16 hours) in a completely randomised design. At 150 days, the following were evaluated: a) number of etiolated shoots; b) number of nodes per etiolated shoot; c) length of... |

| ABSTRACT The aim of this study was to evaluate the development of Chinguensai (Brassica pekinensis L.) seedlings, under different formulations of substrates and sizes of containers, in Fortaleza, Ceará. For this, two studies were conducted in factorial design with randomized blocks and four replicates. The first study was conducted in a factorial (4 × 4) design. Four substrate formulations (powder-type coconut fiber; carbonized rice hull and earthworm casting) had the following proportions: S1 (1:1:1); S2 (0:1:1); S3 (1:0:1); and S4 (0:0:1) by volume basis (v/v) and four evaluation dates (22, 27, 34 and 41 days after sowing — DAS). The second study was conducted in a factorial (3 × 4) design with three types of containers with different cell volumes (31,... |

| Objetivou-se neste trabalho estudar a influência de diferentes concentrações de sacarose no crescimento in vitro de Caularthron bicornutum (Hook.) Raf. O experimento foi conduzido no Departamento de Tecnologia da Faculdade de Ciências Agrárias e Veterinárias, Universidade Estadual Paulista - Unesp/FCAV, em Jaboticabal, São Paulo (SP), no período de janeiro a outubro de 2009. O delineamento experimental foi inteiramente casualizado. Foram seis tratamentos (cinco concentrações de sacarose: 10; 20; 30; 40 e 50g L-1 e ausência de sacarose no meio de cultura) e cinco repetições, totalizando 30 parcelas e 12 plântulas/parcela. A semeadura foi feita em meio de cultura MS e, após 90 dias, estas foram selecionadas e transferidas para frascos contendo meio de... |
