Com base nesses aspectos, foram realizados três experimentos que serão apresentados em capítulos. No primeiro, o objetivo foi verificar a propagação de miniestacas de oliveira ‘Arbequina’ coletadas em diferentes posições do ramo e submetidas a concentrações de ácido indolbutírico (AIB) e substâncias húmicas (SoloHumics®). O delineamento experimental foi o inteiramente casualizado, em esquema bifatorial 3x4 (posições de coleta no ramo (basal, mediana e apical) e concentrações de AIB com SoloHumics® (0 mg L-1 AIB + 10 mL SoloHumics®; 1.000 mg L-1 AIB + 10 mL SoloHumics®; 2.000 mg L-1 AIB + 10 mL SoloHumics®; e 3.000 mg L -1 AIB + 10 mL SoloHumics®)). Conclui-se que a oliveira ‘Arbequina’ pode ser propagada por miniestacas basais e apicais submetidas ao uso de 1.000 mg L-1 de AIB + SoloHumics®, e por miniestacas medianas tratadas com 2.000 mg L-1 de AIB + SoloHumics®, em função do maior potencial de enraizamento. No segundo capítulo, o objetivo foi avaliar a presença e ausência de lesão na base de miniestacas de oliveira ‘Arbequina’ submetidas a concentrações de AIB e SoloHumics®. O delineamento experimental foi o inteiramente casualizado, em esquema bifatorial 2x4 (presença e ausência de lesão na base e concentrações de AIB + SoloHumics® (0 mg L-1 AIB + 10 mL SoloHumics®; 1.000 mg L-1 AIB + 10 mL SoloHumics®; 2.000 mg L-1 AIB + 10 mL SoloHumics®; e 3.000 mg L-1 AIB + 10 mL SoloHumics®). Constatou-se que a oliveira ‘Arbequina’ pode ser propagada por miniestacas com lesão na base submetidas ao uso de 1.000 mg L-1 de AIB + SoloHumics® e por miniestacas sem lesão na base tratadas com 3.000 mg L -1 de AIB + SoloHumics®, em função do maior potencial de enraizamento. No terceiro capítulo, objetivou-se avaliar a utilização de diferentes volumes de recipientes, substratos e tempo de cultivo no desenvolvimento da oliveira ‘Arbequina’. Para isto, o delineamento experimental foi o inteiramente casualizado, em esquema trifatorial para as variáveis altura de planta, número e comprimento médio de brotações, sendo os fatores de tratamento: volumes de recipientes (20 L e 30 L), substratos (casca de arroz carbonizada, Beifort S-10B® e casca de arroz carbonizada + Beifort S-10B®), e tempo de cultivo (30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360 dias). Além disso, para o comprimento de maior raiz e massa de matéria seca de parte aérea e raízes adotou-se o esquema bifatorial, sendo os fatores de tratamento: volumes de recipientes (20 L e 30 L) e substratos (casca de arroz carbonizada, Beifort S-10B®, e casca de arroz carbonizada + Beifort S-10B®). Concluiu-se que o recipiente de 30 L contendo Beifort S-10B® pode ser usado no cultivo da oliveira ‘Arbequina’ durante 360 dias. Olive cultivation is expanding in Brazil; however, in order to meet the different market niches, it is necessary to establish efficient propagation protocols to obtain quality seedlings, as well as to determine the appropriate conditions for their growth and development in containers, aiming at their use in ornamentation. Based on these aspects, three experiments were carried out, which will be presented in chapters. In the first, the objective was to verify the propagation of 'Arbequina' olive minicuttings collected in different positions of the branch and subjected to concentrations of indolebutyric acid (IBA) and humic substances (SoloHumics®). The experimental design was completely randomized, in a 3x4 bifactorial scheme (collection positions in the branch (basal, median and apical) and IBA concentrations with SoloHumics® (0 mg L -1 IBA + 10 mL SoloHumics®; 1,000 mg L-1 IBA + 10 mL SoloHumics®; 2,000 mg L-1 IBA + 10 mL SoloHumics®; and 3,000 mg L-1 IBA + 10 mL SoloHumics®)). It is concluded that the 'Arbequina' olive tree can be propagated by basal and apical minicuttings submitted to the use of 1,000 mg L-1 of IBA + SoloHumics®, and by medium minicuttings treated with 2,000 mg L-1 of IBA + SoloHumics®, in due to the greater rooting potential. In the second chapter, the objective was to evaluate the presence and absence of lesion at the base of 'Arbequina' olive minicuttings subjected to concentrations of IBA and SoloHumics®. The experimental design was completely randomized, in a 2x4 bifactorial scheme (presence and absence of lesion at the base and IBA concentrations with SoloHumics® (0 mg L-1 IBA + 10 mL SoloHumics®; 1,000 mg L-1 IBA + 10 mL SoloHumics®; 2,000 mg L-1 IBA + 10 mL SoloHumics®; and 3,000 mg L-1 IBA + 10 mL SoloHumics®)). It was found that the 'Arbequina' olive tree can be propagated by minicuttings with basal lesion submitted to the use of 1,000 mg L-1 of IBA + SoloHumics® and by minicuttings without base injury treated with 3,000 mg L-1 of IBA + SoloHumics®, due to the greater rooting potential. In the third chapter, the objective was to evaluate the use of different volumes of containers, substrates and cultivation time in the development of the 'Arbequina' olive tree. For this, the experimental design was completely randomized, in a trifactorial scheme for the variables plant height, number and average length of shoots, being the treatment factors: container volumes (20 L and 30 L), substrates (carbonized rice husk, Beifort S-10B® and carbonized rice husk + Beifort S-10B®), and cultivation time (30, 60, 90, 120, 150 , 180, 210, 240, 270, 300, 330, 360 days). In addition, for the longest root length and shoot and root dry matter mass, the bifactorial scheme was adopted, with the treatment factors being: container volumes (20 L and 30 L) and substrates (carbonized rice husk, Beifort S-10B®, and carbonized rice husk + Beifort S-10B®). It was concluded that the 30 L container containing Beifort S-10B® can be used in the cultivation of the 'Arbequina' olive tree for 360 days.
