| Tecidos de rizoma e pseudocaule de bananeira (Musa spp.), de plântulas micropropagadas, dos cultivares Maçã, Nanicão e GN-60 foram utilizados para indução de estruturas embriogênicas. Explantes obtidos desses tecidos foram cultivados em meio de cultura, segundo Schenk & Hildebrandt, com vitaminas de Staba em concentrações modificadas por Novak et al., acrescido do regulador de crescimento Dicamba, nas concentrações de 0; 2,0; 3,5 e 6,63 mg/L. A formação de tecidos com capacidade embriogênica (calos e estruturas globulares) foi observada em tecidos localizados próximo ao ápice meristemático, para os três cultivares testados. A partir dessas estruturas, foram obtidas suspensões celulares que deram origem a estruturas semelhantes a embriões somáticos,... |

| ABSTRACT The aim of this study was to induce and analyze embryogenic calli from two types of explants (leaves and meristems) of the hybrid Eucalyptus grandis x Eucalyptus urophylla. Leaves and meristems of plants kept in a nursery were disinfected and inoculated in Petri dishes containing MS culture medium supplemented with different concentrations of the growth regulator dicamba (1.13, 4.52, and 9.04 µM) and without it. At 60 days of culturing, the calli were analyzed by scanning electron microscopy and at 90 days were evaluated by light microscopy in regard to the embryogenic characteristics of the cells. Different type of calli were induced in leaf explants, designated as Type I with light yellow coloring, Type II with dark yellow coloring, and Type III... |

| ABSTRACT: Sugarcane industries are faced with the challenges of reduced cane yield due to inability to ascertain an appropriate sugarcane planting density. Field trials were conducted at Bacita, southern Guinea savanna of Nigeria to examine appropriate planting density and weed control method that can minimize weed infestation in sugarcane field and give an optimum cane yield to improve the economic status of the sugarcane farming community. The experiment was established as a randomized complete block design in a split-plot arrangement with three replications. The main plot constituted four planting populations (43,200, 64,800, 86,400 and 108,800) plants ha-1 while the sub-plot consisted of six weed control practices (weedy check, pre-emergence... |

| The present work analyzes the behavior of banana explants, cv. Nanicão (Musa spp. Group AAA) regarding somatic embryogenesis induction treatments with several auxins. Longitudinal segments of shoot meristematic apices of micropropagated banana plantlets cultivated and rooted in vitro were introduced in culture medium containing dicamba, picloram, 2,4-D or NAA in different concentrations. Explant samples were collected at 0, 7 and 10 days and prepared for light microscopy. Histological sections were used for comparison of the histological changes occurring after induction treatment with different auxins. Embryogenic response was observed only in treatments with picloram or dicamba, with distinct embryogenic regions observed at 14 and 21 days in culture,... |
