O objetivo deste trabalho foi avaliar características pós-colheita da primeira haste floral de plantas de Heliconia psittacorum x H. spathocircinata Aristeguieta, cultivar Golden Torch, sob deficiência de macronutrientes. O experimento foi conduzido em casa de vegetação, mediante técnica do elemento faltante. As inflorescências produzidas do tratamento sob omissão de N apresentaram coloração laranja-pálido e deformação nas hastes florais. O comprimento e o diâmetro da haste floral e o comprimento da inflorescência foram reduzidos nos tratamentos com omissão de N, P ou K em até 31,23%, em relação ao tratamento completo. A massa de matéria seca e a durabilidade pós-colheita das hastes florais foram reduzidas em 67 e 38,46%, respectivamente, em ambos os... |

The objective of this study was to characterize nutritional deficiencies in Heliconia psittacorum x Heliconia spathocircinata 'Golden Torch', through growth indicators, symptomatology and macronutrients contents in leaves and underground plant part. The experiment was carried out in a greenhouse, with eight treatments comprising complete nutrition solution (N, P, K, Ca, Mg, S), solution with individual nutrient omission of N, P, K, Ca, Mg or S and solution lacking all nutrients. The symptoms of nutrients deficiency appeared in the following occurrence order: N, K, P, Mg and S. Deficiency symptoms were: general chlorosis to - N omission; slight chlorosis to - P and - S; dark green leaves and necrosis to - K; marginal chlorosis and necrosis to - Mg. Calcium... |

ABSTRACT: The objective of the present research was to develop a protocol for micropropagation of Anthurium bonplandii and Anthurium maricense by direct organogenesis. Nodal segments, with two or three nodes, were used as explants. The cultures were kept in a growth chamber at a temperature of 25±2ºC, under a photoperiod of 16 hours and a luminosity of 30μmol m-2 s-1. At 60 days, the number of regenerated buds per explant (NBE) was counted. The experiment was carried out in an entirely randomised design consisting of six treatments for six different concentrations of 6-benzylaminopurine (6-BA) added to the P2 (Pierik) medium (0.0, 1.11, 2.22, 3.33, 4.44, and 5.55µM). All the treatments were performed in four repetitions with 10 culture tubes containing one... |
