Abstract This study aimed to evaluate the biocontrol potential of bacteria isolated from different plant species and soils. The production of compounds related to phytopathogen biocontrol and/or promotion of plant growth in bacterial isolates was evaluated by measuring the production of antimicrobial compounds (ammonia and antibiosis) and hydrolytic enzymes (amylases, lipases, proteases, and chitinases) and phosphate solubilization. Of the 1219 bacterial isolates, 92% produced one or more of the eight compounds evaluated, but only 1% of the isolates produced all the compounds. Proteolytic activity was most frequently observed among the bacterial isolates. Among the compounds which often determine the success of biocontrol, 43% produced compounds which... |

A shoot regeneration system for Plectranthus neochilus was studied from leaf explants. Leaves developed under in vitro conditions were cultured on Wood Plant Medium supplemented with 0.2mg dm-3 α-naphthaleneacetic acid (NAA) and different 6-benzilaminopurine (BAP) or thidiazuron (TDZ) concentrations (0, 1.5, 3.0, 4.5 and 6.0mg dm-3). An increase in percentage of responsive explants (85.3%) and in the number of shoots developed per explant (3.2) was observed when the explants were treated with 5.3 and 4.7mg dm-3 BAP, respectively. The leaf explants cultured on media supplemented with TDZ became vitreous and did not form buds. The regeneration system used is efficient for boldo bud induction and shoot development, showing high potential for advanced cellular... |

Pomares comerciais de ameixeira-japonesa devem conter pelo menos duas cultivares para obter boa fertilização, devido à presença do sistema de incompatibilidade gametofítica, que inibe a autofecundação da grande maioria das cultivares. No presente trabalho, buscou-se identificar e caracterizar molecularmente os alelos-S de 11 cultivares de ameixeira-japonesa (Prunus salicina Lindl.) e verificar a compatibilidade entre os genótipos avaliados. As cultivares Santa Rosa, Santa Rita, Reubennel, Pluma 7, América, Rosa Mineira, Amarelinha, The First, Gulfblaze (Clone São Paulo), Gulfblaze (Clone Guaiba) e Harry Pickstone foram analisadas por meio de Reação em Cadeia da Polimerase (PCR) com três pares de iniciadores específicos para alelos-S. As condições da PCR... |
