“…The metal clip was inferior to the others in the protection of the grafted region due to the oxidation of the material, but the others provided 100% seedling survival at 60 DAG. High compatibility between P. edulis and P. mucronata was observed in the works of Alexandre et al (2013) and Oliari et al (2016). The same was observed by Morgado et al (2015), when grafting P. edulis on P. mucronata, with seedling height values of 74.13 cm at 75 days after grafting; at the moment of planting seedlings with at least 15 cm are recommended.…”

“…As the graft is composed of stem apexes, its cells are younger (absolute growth rate of 2.5 cm day -1 , in addition to being a tender and very hydrated tissue) and for being meristematic tissue, site of auxin synthesis, they show higher cell division rate. Oliari et al (2016) also observed, at 21 DAM, mitoses only of graft cells.…”

“…mucronata, in which the establishment was 80% was observed. Oliari et al (2016), in a study on the mini-grafting of P. edulis on P. mucronata obtained 89% of live seedlings at 21 days after grafting (DAG). Cavichioli et al (2011) verified the survival of 91% of P. edulis/Passiflora gibertti N. E. Brown seedlings grown in an area infected with Fusarium solani and nematode Rotylenchulus reniformis.…”

“…The explanation for this may be related to the morphological aspects of stems, such as the pentagonal shape in P. edulis and circular shape in P. mucronata and the time of contact between graft and rootstock of 60 days, requiring more than this time for complete filling. Oliari et al (2016) observed that the use of a circular V-shape clip, and Parafilm ® tape fastener aided the attachment of the graft (P. edulis) and the rootstock (P. mucronata) at 21 DAM, and that cell multiplication did not fully occur in the graft cleft, requiring longer time for the cell multiplication to complete the connection between bionts. Complete filling by calogenic cells in the P. edulis/P.…”

In Brazil, the main cultivated passion fruit species is Passiflora edulis, which is affected by Fusarium soil fungus. P. mucronata species stands out because it presents resistance to this fungus, being thus an alternative rootstock to yellow passion fruit. Therefore, the aim of this study was to evaluate the anatomy of mini-grafting by top cleft grafting and simple English type grafting, using shoot tips of adult P. edulis plants in clonal rootstocks of P. mucronata. When the rootstocks reached approximately 2.5 mm in diameter and 20 cm in height, grafting was carried out with Parafilm® tape fasteners and silicone clip. At the end of 60 days, histological analysis of the grafting region was performed to verify the formation of the scarring parenchyma tissue (callus). The filling of the mini-grafting cleft by callus was verified; however, there was no differentiation of the new vascular tissue at 60 days after grafting. During the performance of the simple English type grafting using Parafilm® tape, it was extremely difficult to encircle the tape and at the same time to join the bionts so that tissue junction is perfect. Mini-grafting by top cleft grafting using Parafilm® tape fastener is recommended.

“…A espécie P. mucronata também vem apresentando elevado interesse devido à resistência a algumas doenças e, portanto, torna-se alternativa como porta-enxerto sob P. edulis f. flavicarpa (OLIARI et al, 2016), além do potencial para uso ornamental, com flores brancas que se abrem à noite, e de se mostrar tolerante ao frio, com produção ininterrupta de folhas o ano todo .…”

Resumo: A espécie Passiflora mucronata apresenta bom potencial para uso como porta-enxerto do maracujá azedo, por ser resistente a algumas doenças, e como ornamental. Conhecendo-se, no entanto, pouco a respeito de sua fisiologia. A obtenção da área foliar é fundamental em vários estudos agronômicos, sendo um dos importantes instrumentos que avaliam o crescimento da planta. Objetivou-se com este trabalho estudar a modelagem estatística da área foliar de Passiflora mucronata, cultivada nos ambientes casa de vegetação e campo, a partir de dimensões lineares de comprimento e maior largura do limbo. A área foliar observada foi medida com o auxílio do software ImageJ ® por análise de imagens digitalizadas das folhas. Foram estimadas equações por meio de modelos de regressão linear, potência e exponencial para os dois tipos de ambiente, e verificada a possibilidade de uso de apenas uma equação que represente a área foliar em plantas dos dois ambientes. As equações foram validadas a partir de outras amostras. Conclui-se que a determinação da área foliar de Passiflora mucronata pode ser feita de forma não destrutiva com o uso da maior largura do limbo, e a equação AFE = 1,8963 L 1,7275 representa a área foliar tanto para casa de vegetação quanto para campo. Palavras-chave:Biometria. Método não-destrutivo. Modelagem da área foliar. Abstract:The species Passiflora mucronata shows good potential for use as rootstock with the sour passion fruit, as it is resistant to some diseases, and as an ornamental plant; little is known however about its physiology. Obtaining the leaf area is fundamental in several agronomic studies, being one of the important methods for evaluating growth in the plant. The aim of this work was to study statistical modelling of the leaf area in Passiflora mucronata, grown in a greenhouse and in the field, from linear dimensions of the length and greatest width of the blade. The leaf area being observed was measured with the aid of the ImageJ ® software by the analysis of scanned leaf images. Equations were estimated using linear, exponential and power regression models for both types of environment, and the possibility was checked of using only one equation, which would represent leaf area in plants from the two environments. The equations were validated from other samples. It was concluded that determining leaf area in Passiflora mucronata could be carried out in a non-destructive way using the largest width of the blade, and that the equation AFE = 1.8963 W 1.7275 represents leaf area both for in the greenhouse and in the field.
