“…Within this subgenus, there is a group of species with floral tubes ranging from a few to 14 cm long (figure 1). These passionflowers are grouped into supersection Tacsonia, which comprises 62-64 species, all restricted to the high Andes at 1700 to approximately 4000 m ( [8][9][10][11]; figure 2b). Passiflora supersection Tacsonia is characterized by several morphological traits, suggesting that the group might be monophyletic [9], although this has not really been tested.…”

Escape from extreme specialization: passionflowers, bats and the sword-billed hummingbird

A striking example of plant/pollinator trait matching is found between Andean species of Passiflora with 6–14-cm-long nectar tubes and the sword-billed hummingbird, Ensifera ensifera , with up to 11-cm-long bills. Because of the position of their anthers and stigmas, and self-incompatibility, these passionflower species depend on E. ensifera for pollination. Field observations show that the bird and plant distribution match completely and that scarcity of Ensifera results in reduced passionflower seed set. We here use nuclear and plastid DNA sequences to investigate how often and when these mutualisms evolved and under which conditions, if ever, they were lost. The phylogeny includes 26 (70%) of the 37 extremely long-tubed species, 13 (68%) of the 19 species with tubes too short for Ensifera and four of the seven bat-pollinated species for a total of 43 (69%) of all species in Passiflora supersection Tacsonia (plus 11 outgroups). We time-calibrated the phylogeny to infer the speed of any pollinator switching. Results show that Tacsonia is monophyletic and that its stem group dates to 10.7 Ma, matching the divergence at 11.6 Ma of E. ensifera from its short-billed sister species. Whether pollination by short-billed hummingbirds or by Ensifera is the ancestral condition cannot be securely inferred, but extremely long-tubed flowers exclusively pollinated by Ensifera evolved early during the radiation of the Tacsonia clade. There is also evidence of several losses of Ensifera dependence, involving shifts to bat pollination and shorter billed birds. Besides being extremely asymmetric—a single bird species coevolving with a speciose plant clade—the Ensifera / Passiflora system is a prime example of a specialized pollinator not driving plant speciation, but instead being the precondition for the maintenance of isolated populations (through reliable seed set) that then underwent allopatric speciation.

“…Bats pollinate another seven species that have greenish or white flowers [11,14]. Like most Passiflora, Tacsonia species are self-incompatible and depend on cross-pollination to set seed [10].…”

“…Passiflora laurifolia L. is cultivated in the Caribbean, however it is not commercially cultivated in French Guiana. Another species in this series, P. popenovii Killip, is highly prized in the Andes of Southern Colombia and Southern Ecuador (Yockteng et al 2011).…”

“…They appear to occupy similar forest habitats, often close to small streams and temporarily flooded areas. This capacity to withstand excessive soil water is an interesting rare trait in Passiflora, with potential interest for the main commercial species, which are sensitive to root diseases (Yockteng et al 2011).…”

Passiflora kapiriensis is a new Guianese species in the series Laurifoliae of subgenus Passiflora, found near Saint-Georges-de-l'Oyapock. The filaments of the fourth corona row are 1 cm long and oriented to the androgynophore, which is reminiscent of P. acuminata, P. cerasina, P. fissurosa, P. killipiana and P. nitida. It differs from these close relatives by the combination of subequal first and second rows of filaments, a very short hypanthium, very long petioles, with medial nectary glands, and much larger leaves.

ABSTRACT. This study analyzed the genotype x environment interaction (GE) for the juice productivity (JuProd) of 12 yellow passion fruit varieties (Passiflora edulis Sims. f. flavicarpa Deg.) using additive main effects and multiplicative interaction (AMMI) model and auxiliary parameters. The experiments were conducted in eight environments of Bahia State, Brazil, using a randomized block design with three replications. Analysis of variance showed significant effects (P ≤ 0.01) for environments, genotypes, and GE interaction. The first two interaction principal component axes (IPCAs) explained 81.00% of the sum of squares of the GE interaction. The AMMI1 and AMMI2 models showed that varieties 09 and 11 were the most stable. Other parameters, namely, the AMMI stability value (ASV), yield stability (YSI), sustainability, and stability index (StI), indicated that other varieties were more stable. These varying results were certainly a consequence of methodological differences. In contrast, the ranking of varieties for each of the stability parameters showed significant positive correlations (P ≤ 0.05) between IPCA1 x (ASV, YSI), JuProd x (StI, YSI), YSI x ASV, and StI x YSI. Cluster analysis based on the genotypic profile of the effects of the GE interaction identified three AMMI analysis of passion fruit groups that correlated with the distribution of varieties in the AMMI1 biplot. However, the classification of stable genotypes was limited because the association with the productivity was not included in the analysis. Variety 08 showed the most stable and productive behavior, ranking above average in half of the environments, and it should be recommended for use.
