| ABSTRACT Poincianella pyramidalis (Tul.) L.P. Queiroz, is an arboreal species endemic to Brazil’s Caatinga biome and an important source of lumber and also of medicinal substances. This study aimed to evaluate the effect of the osmotic agents sucrose, sorbitol and mannitol and the growth retardant paclobutrazol (PBZ) on the induction of slow growth in vitro of P. pyramidalis, seeking to establish alternative techniques for ex situ conservation of the species. In the first experiment, plantlets with seven days of age were inoculated on Woody Plant Medium (WPM) supplemented with four concentrations of sucrose (87.64, 131.46, 175.28 or 219.10 mM) combined with 0.0 or 87.64 mM sorbitol or mannitol. In the second experiment, these plantlets were inoculated on... |

| 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... |

| Abstract: The objective of this work was to evaluate the effects of temperature and osmotic agents on the in vitro conservation of Cape gooseberry (Physalis peruviana). Temperatures at 18 and 25°C, as well as the osmotic agents sucrose, mannitol, and sorbitol were tested. A short-term in vitro conservation of Cape gooseberry can be achieved at 18°C, using 30 g L-1 sucrose. |
