Detailed knowledge on the factors influencing the production of minicuttings, especially focusing on management and environmental optimization is important. Therefore, this study aimed at evaluating the influence of temperature, relative humidity and PAR (photosynthetically active radiation) and their oscillations in mini-clonal hedges of three E. benthamii x E. dunnii hybrid clones regarding survival, vigor and productive capacity of ministumps. A mini-clonal hedge with a semi-hydroponic system was formed, with five replicates of five ministumps per clone, submitted to 41 successive collections of minicuttings during one year. A multiple linear regression model for minicutting production was adjusted according to maximum, average and minimum climatic variables, considering a period from 0 until 16 weeks before collection. Ministumps from three clones showed 100 % survival throughout the year. Clone 1 showed higher production (8,000 minicuttings m-2 month-1) and clone 3 showed the lowest values for this variable (less than 5,000 minicuttings m-2 month-1). The adjusted multiple linear regression model was formed by the maximum PAR, maximum humidity and temperature range of different weeks before collection. Maximum PAR (1,440-1,600 µmol m-² s-1) was the most influential variable in the adjusted model and positively related to minicutting productivity. Based on ideal climatic values found by the regression model, it is possible to suggest that climatic oscillations do not favor ministump development.

A especie Mycosphaerella musicola Leach (forma anamorfica Pseudocercospora musae (Zimm) Deighton) e o mais importante patogeno da bananeira no Brasil, causador da doenca mal-de-sigatoka, Sigatoka amarela ou cercosporiose. Apesar da importancia do patogeno em estudo, nada se conhece sobre a sua variabilidade patogenica e pouco se conhece sobre a interacao patogeno-hospedeiro no que diz respeito a resistencia. Com base nestas observacoes, elaborou-se o presente trabalho com objetivos de avaliar a presenca de variabilidade patogenica entre isolados de M. musicola, avaliar e caracterizar a resistencia induzida em variedades de banana, suscetiveis ao mal-de-sigatoka, quando inoculadas com racas incompativeis de M. musicola e.ou quando inoculadas com racas compativeis, mas mantidas em ambiente improprio ao desenvolvimento da doenca; avaliar a resistencia genetica a Sigatoka amarela apresentada por diferentes genotipos de bananeira e chegar a uma metodologia de avaliacao da resistencia, capaz de substituir a tradicional avaliacao de campo. |
