| ABSTRACT: The establishment of olive (Olea europaea) orchards in Brazil is increasing due to their economic potential and benefits to human health. However, a number of limiting factors need to be overcome, such as Olive Leaf Spot (OLS) occurrence, for olives to reach their full potential. OLS, which is caused by Fusicladium oleaginum, results in defoliation and a reduction in fruit production. This study aimed to develop a standard area diagram set (SAD) for the assessment of OLS severity under humid subtropical climate conditions. The SAD was developed with six levels of severity (1, 3, 6, 9, 12 and 15%) and OLS severity was validated by eight inexperienced raters. Using the SAD provided an increase in accuracy, precision and concordance, while also... |

| RESUMO: A predição de valores de área foliar (AF) sem a destruição de plantas é de grande interesse nas pesquisas agronômicas. Neste trabalho, foram desenvolvidos e testados três modelos de predição de AF, utilizando-se a largura (L), o comprimento (C) ou em ambas as dimensões da folha de pessegueiro 'BRS Kampai'. Testou-se também um modelo genérico de DEMIRSOY et al. (2004), proposto para determinar AF em pessegueiro e desenvolvido nas condições de cultivo da Turquia. O uso de apenas uma dimensão, visando a reduzir a onerosidade nas avaliações, não permite predições adequadas e podem levar a erros estatísticos por alterar a variabilidade dos dados em relação às AF reais. O modelo não destrutivo proposto neste trabalho foi... |

| Abstract Early-ripening peach cultivars present difficulties in the process of natural germination of seeds. In order to solve this problem, the culture of embryos in vitro can be considered an alternative, in which seeds find conditions to complete germination and development in a satisfactory way. Different protocols and culture media have been tested to meet the nutritional needs of the embryo, but they still have problems and need to be optimized. The objective of this work was to test culture media and BAP concentrations in order to increase the germination percentage of embryos and viable ‘BRS Kampai’ peach seedlings, avoiding possible anomalies in the process. The experiment was carried out at the Laboratory of Tissue Culture – “Universidade... |
