(Reproductive phenology of plant species of Mixed Ombrophilous Forest in Paraná, Brazil). The Mixed Ombrophilous Forest (FOM) or Araucaria Forest, vegetation that occupies regions with a highly seasonal climate subject to frost, used to cover 40% of Paraná State. Nowadays, however, there is less than 1% of advanced and well conserved FOM covering this State. This study presents the reproductive phenological patterns (flowering and fruiting) of the plant species found in FOM fragments located in three municipalities of Paraná State in order to subside restoration activities. Monthly phenological observations in 543 individuals of 145 species, representing several life forms (71 trees, 52 bushes, 18 vines and four epiphytes) were conducted between January 2004 and December 2005 employing the activity index. Flowering was recorded mainly between September and December, with a peak in October and November (68 species), followed by fruiting, which was concentrated between December and April, peaking in February (61 species). During the coldest months (June to August), the number of species with flowers or fruits was very low, with less than five species per phenophase. The availability of araucaria (Araucaria angustifolia (Bertol.) Kuntze) seeds varied between the years, but usually occurred between April and September. Significant correlations between phenophases and some abiotic factors, especially day length and temperature, were found. Therefore, plant species of the FOM proved to be highly seasonal, with periods of high and low flowering and fruiting activity, as consequence of the climatic seasonality, characteristic of the study region.

As castor bean (Ricinus communis L.) reveals immense adaptability to various ecological conditions and due to its socioeconomic significance, new studies have emerged primarily to develop more productive cultivars to suit different regions in Brazil. This study aimed to confirmthe correlations and direct and indirect effects of the morphoagronomic descriptors on castor bean productivity, employing correlation studies and track analysis. Between 2014 and 2015, experiments utilizing the randomized block design were performed, with four replications, which included 208 treatments involving pedigree and parental lines of castor bean, drawn from the germplasm bank of the Universidade Federal do Recôncavo da Bahia. Variables in the correlation analysis included primary racemic insertion, stem diameter, number of stem internodes, plant flowering, plant height, racemic length, number of fruits per raceme, fruit weight per raceme, seed yield per fruit and productivity. Correlations among the variables analyzed were imposed, via track analysis, on the direct and indirect influences of the morphoagronomic descriptors on productivity. The most direct and positively influential descriptors included fruit weight per raceme and number of seeds per raceme; the most direct albeit negatively influential descriptors are the number of internodes on the stem and flowering. Therefore, lines with less number of internodes and requiring fewer days to bloom are more highly productive. These descriptors can thus effectively identify the productive lines.
