Araucaria angustifolia (araucaria) is a remarkable species in the Mixed Ombrophilous Forest. The low germination of the stored seeds and its long reproductive cycle make grafting a good alternative for propagation, making possible to obtain genetically superior trees with early fruiting. However, araucaria grafting is still fraught with technical problems, culminating in low graft survival. With the objective to define and be able to explain the best methodology for the grafting of araucaria, we conducted studies based on five experiments evaluating the effects of: (I) environment and sex on graft survival; (II) methods of grafting and budding with shoots from stumps of stock plants; (III) techniques, indoor (nursery) and outdoor (directly in the field) grafting; (IV) budding with buds from different origins; and (V) chip budding with shoots from pruned apices of two ages stock plants. Graft survival was assessed throughout the experiments and the graft-union at the end. The use of controlled environments for grafting was favorable, especially in the glasshouse (64.1 % survival). Scions from female plants (55.5 % survival) showed higher suitability for grafting. Chip budding with shoots from pruned apices of 25 and 35-year-old stock plants showed survival of 87.5 % and 85.0 %, respectively. It is a technology that has unlimited potential for araucaria grafting, which may significantly contribute to its sustainable use. |

Many studies have been pointing to a high diversity of bacteria associated to legume root nodules. Even though most of these bacteria do not form nodules with legumes themselves, it was shown that they might enter infection threads when co-inoculated with rhizobial strains. The aim of this work was to describe the diversity of bacterial communities associated with cowpea (Vigna unguiculata L. Walp) root nodules using 16S rRNA gene amplicon sequencing, regarding the factors plant genotype and soil type. As expected, Bradyrhizobium was the most abundant genus of the detected genera. Furthermore, we found a high bacterial diversity associated to cowpea nodules; OTUs related to the genera Enterobacter, Chryseobacterium, Sphingobacterium, and unclassified Enterobacteriacea were the most abundant. The presence of these groups was significantly influenced by the soil type and, to a lesser extent, plant genotype. Interestingly, OTUs assigned to Chryseobacterium were highly abundant, particularly in samples obtained from an Ultisol soil. We confirmed their presence in root nodules and assessed their diversity using a target isolation approach. Though their functional role still needs to be addressed, we postulate that Chryseobacterium strains might help cowpea plant to cope with salt stress in semi-arid regions. |
