E-mail: [email protected] Científico do CNPq   1 RESUMO  Determinou-se à demanda hídrica e o coeficiente de cultivo (Kc) do maracujá amarelo (Passiflora edulis Sims f. flavicarpa Deg.), seleção Sul-Brasil, cultivado sob irrigação localizada, no município de Botucatu-SP (22o 51’ S,  48o 26’ W). A evapotranspiração máxima da cultura (ETc) e a evapotranspiração de referência (ETo) foram medidas em lisímetros de nível de lençol freático constante, durante o período de 29 de setembro de 2000 a 20 de julho de 2001. Os valores da ETc e ETo foram de 954,98 mm e  1.069,21 mm, respectivamente, durante todo o período medido. Os valores de Kc variaram de 0,42 a 1,12, com os valores máximos registrados entre 150 e 210 dias após o transplantio das mudas no campo (DAT), período correspondente aos estádios fenológicos de florescimento e formação dos frutos.  UNITERMOS: Passiflora edulis, evapotranspiração, coeficiente de cultivo (Kc).   SILVA, A.A.G. da, KLAR, A.E.  YELLOW PASSION FRUIT (Passiflora edulis Sims f. flavicarpa Deg.)

The objective was to evaluate the percentage of emergency plantlets and lipid peroxidation in seeds of 29 half-sib progenies of yellow passion fruit (Passiflora edulis Sims.) after 24 months under storage. The experimental design was completely randomized, with four replications of 50 seeds each, from which the treatments were the progenies (1-29). The evaluation of the percent plantlet emergency was accomplished at 14 and 28 days after sowing. The lipid peroxidation of the seeds was expressed as malondialdehyde (MDA) content that was determined by the TBARS method. Approximately 21% of those half-sib progenies maintained the viability of their seeds for twenty-four months under storage. The results point out a remarkable genetic variability for vigor and emergency of the yellow passion fruit plantlets, with occurrence of individuals with high and other ones with low capacity to maintaining the physiologic quality of their seeds after storage.

A eficácia na produção de plântulas de maracujá-amarelo (Passiflora edulis Sims e F. flavicarpa Deg) pode ser afetada pela germinação irregular, devido, principalmente, a um curto período de dormência das sementes, bem como ao uso do substrato errado. Assim, o objetivo deste trabalho foi avaliar o efeito de três temperaturas de armazenamento e três substratos durante o desenvolvimento inicial de plântulas de maracujazeiro amarelo. O experimento foi conduzido em casa de vegetação agrícola na Universidade Federal de Pelotas, RS. Após a retirada da mucilagem e secagem, as sementes foram acondicionadas em embalagens de papel Kraft e armazenadas a 5 ºC, 10 ºC e temperatura ambiente (18 ± 0,6 ºC) por 15 dias. Em seguida, eles foram cultivados em fibra de coco Amafibra®, casca de arroz carbonizada e S-10Beifort®. Sementes mantidas a 18 ºC apresentaram menor comprimento da raiz sem diferença entre os armazenados a 5 ºC. Não houve efeito da temperatura na emergência, comprimento da parte aérea, número de folhas e biomassa seca da parte aérea e das raízes. A maior porcentagem de germinação foi encontrada no substrato da casca de arroz carbonizada; no entanto, com exceção do maior comprimento radicular e da biomassa seca da parte aérea e das raízes, o desenvolvimento das plantas foi superior com os demais substratos. Assim, a utilização de temperatura de 10 ºC durante o armazenamento, bem como fibra de coco e S-10 Beifort® como substratos são as melhores recomendações para melhorar a emergência e desenvolvimento inicial do maracujá-amarelo. com exceção do maior comprimento radicular e da biomassa seca da parte aérea e das raízes, o desenvolvimento da planta foi superior com os demais substratos.

Abstract 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.

Passiflora edulis, the passion fruit native from Brazil, has several common names (such as sour passion fruit, yellow passion fruit, black passion fruit, and purple passion fruit), and presents a wide variability with the different rind colors of its fruits, which are very easy to notice. However, in 1932, Otto Degener suggested that the yellow passion fruit had its origin in Australia through breeding, calling it P. edulis forma flavicarpa, and that it could be distinguished by the color of the fruit, the deeper shade of purple of the corona, and the presence of glands on the sepals. These distinctions do not support themselves, for the glands are common to the species (although they may be absent), and the corona has a wide range of colors, regardless of the color of the fruit. A more critical ingredient is the fact that the external coloration of the fruit is a character of complex inheritance and is not dominant, thus displaying a number of intermediate colors, making it difficult to identify the extreme colors. For the correct scientific naming of agricultural plants, the International Code of Botanical Nomenclature must be used in conjunction with the International Code of Nomenclature for Cultivated Plants, with the selections with significant agronomic characteristics recognized and named cultivars. In accordance with the international convention promoted by the UPOV, of which Brazil is a signatory, several colors (light yellow, yellow, orange yellow, pink red, red, red purple, green purple, purple, and dark purple) can be recognized in order to adequately characterize passion fruit cultivars within the species P. edulis. At taxonomic level, Passiflora edulis Sims must be used for any plant and color of sour passion fruits, in combination with a cultivar name for the selected materials.

In the present work, we analyzed the histochemical aspects of Passiflora edulis seeds reserve mobilization during the first ten days of germination. Our results showed that mainly lipids present in the endosperm are used as a reserve source, and their levels reduce at the same time the radicle protrudes, between the fourth and sixth day of sowing. Furthermore, protein bodies are present in the cotyledons, which are degraded as germination occurs and are almost depleted by the time of radicle protrusion. Starch grains also appear in the late germination period, and it is not clear if there is any reserve wall polysaccharide consumption in the endosperm.
