HONEY BEE CONTRIBUTION TO ‘BORDÔ’ GRAPEVINE FRUIT PRODUCTION IN SOUTHERN BRAZIL Rev. Bras. Frutic.
MARTIGNAGO,MIRELI; MARTINS,RAFAEL; HARTER-MARQUES,BIRGIT.
ABSTRACT The production of fruits and seeds of many crops is increased when bees visit their flowers pollinating them. The aim of this study was to evaluate the effect of different pollination treatments on ‘Bordô’ grapevine (Vitis labrusca L.) fruit quantity and quality. Quantitative and qualitative fruit production parameters of plants visited by Apis mellifera L., manually self- and cross-pollinated plants and plants without pollination were analyzed and compared. Fruit production was high for all treatments and all fruits presented four seeds per fruit, on average, confirming that this grape cultivar is autogamous. However, fruit set after spontaneous self-pollination was statistically lower than that of all other treatments, and pollination by A....

Reproductive phenology in a riparian rainforest in the south of Santa Catarina state, Brazil Anais da ABC (AABC)
CASCAES,MAINARA F.; CITADINI-ZANETTE,VANILDE; HARTER-MARQUES,BIRGIT.
Phenological studies assist in forest ecosystems comprehension and evaluation of resource availability for wildlife, as well as in improving the understanding of relationships between plants and their pollinators and dispersers. This study aims to describe the reproductive phenophases of riparian plant species and correlate them with climatic variables. The reproductive phenology was analyzed biweekly throughout one year, recording the absence or presence of flowers/fruits. The flowering phenophase occurred throughout the year, with an increase in number of species in blossom in October, November, and December. The flowering peak of the community was observed in November. The fruiting phenophase also occurred throughout the year and showed an increase of...
