The treatment of seeds using growth regulators can overcome seed dormancy and increase the emergence and development of seedlings. The objective of this research was to evaluate the effect of different concentrations of GA4+7 + N-(phenyl methyl)-aminopurine on the dormancy breaking of Passiflora cincinnata Mast. seeds recently harvested and stored for six years. The study was conducted in a greenhouse at Embrapa Cassava and Tropical Fruits, in completely randomized design, in a 2 x 4 factorial scheme, with the following factors: year of seed harvest (2010 and 2016) and the emergence promoter GA4+7 + N-(phenyl methyl)-aminopurine at four concentrations (0%; 0.03%; 0.45% and 0.90%), with 4 replicates of 25 seeds. Emergence percentage, first count, emergence speed index, number of leaves, root length, stem diameter, dry matter of shoots, roots and total, and root/shoot ratio were evaluated. The results showed that GA4+7 + N-(phenyl methyl)-aminopurine is recommended to overcome dormancy of Passiflora cincinnata in recently harvested seeds (2016) and increase the emergence of seedlings from seeds stored for six years in cold chamber (2010). The emergence promoter concentration of 0.03% can be used to overcome dormancy in recently harvested seeds and maintains the vigor of seeds stored for six years. Passiflora cincinnata seeds remain physiologically viable for six years and their emergence is potentiated by the use of GA4+7 + N-(phenyl methyl)-aminopurine. |

Plant functional traits can predict community assembly and ecosystem functioning and are thus widely used in global models of vegetation dynamics and land?climate feedbacks. Still, we lack a global understanding of how land and climate affect plant traits. A previous global analysis of six traits observed two main axes of variation: (1) size variation at the organ and plant level and (2) leaf economics balancing leaf persistence against plant growth potential. The orthogonality of these two axes suggests they are differently influenced by environmental drivers. We find that these axes persist in a global dataset of 17 traits across more than 20,000 species. We find a dominant joint effect of climate and soil on trait variation. Additional independent climate effects are also observed across most traits, whereas independent soil effects are almost exclusively observed for economics traits. Variation in size traits correlates well with a latitudinal gradient related to water or energy limitation. In contrast, variation in economics traits is better explained by interactions of climate with soil fertility. These findings have the potential to improve our understanding of biodiversity patterns and our predictions of climate change impacts on biogeochemical cycles. |
