Pollination ecology and floral scent chemistry of Philodendron fragrantissimum (Araceae)

2021

View full text Add to dashboard Cite

In French Guiana, Philodendron fragrantissimum (Hook.) G.Don was specifically pollinated by a single species of night-active cyclocephaline scarab, Cyclocephala simulatrix Höhne. Its inflorescences exhibited short-lasting anthesis (~30h) and characteristic floral traits such as floral thermogenesis, edible/nutritious floral tissues, and profuse floral scent emission. Our insect exclusion experiments indicate that entomophilous cross-pollination is obligatory for P. fragrantissimum, with olfactory signalling playing a pivotal role in pollinator attraction.Three volatile organic compoundsmethyl benzoate, (Z)-jasmone, and dehydrojasmone -2 dominate the floral scent of pistillate phase inflorescences (84-99%), but their relative proportions were different according to the headspace sampling method used, dynamic or static.Local pollination services provided by both female and male C. simulatrix are effective, as evidenced by a high visitation rate (>70%) that resulted in 55% of the inflorescences maturing into infructescences. Moreover, pollination was highly efficient, since 2 -3 beetles sufficed to pollinate an average 94% of the pistillate flowers.

Tania or cocoyam (Xanthosoma sagittifolium (L.) Schott) is a member of Araceae; the cormels contain carbohydrate that is valuable in the food industry and to supports food security. However, information on the diversity in cocoyam accessions to support higher productivity and breeding program is still limited. The research aimed to characterize morpho-physiology and diversity of cocoyam accessions. The research was carried out from December 2018 to July 2019 at the Leuwikopo Experimental Farm, IPB Bogor. The research used seven accessions collected by the Agency for the Assessment and Application of Technology (BPPT) namely S8, S22, S27, S29, S31, S32, and S37. Accessions were maintained with a spacing of 50 cm x 50 cm under 50% shading net. Cluster analysis used the unweighted pair group method using the arithmetic average (UPGMA) method. The study showed that there was diversity in 31 of the 51 morphological and physiological characters. Of the 31 various variables, only 14 variables had a PIC value of more than 0.5. The color of the inner petiole and stomatal density were important characters in the characterization of cocoyam because it had the highest diversity. At the accession level, they were grouped into two groups, Group I had accession S29 members, and the rest were grouped into Group II. Group II had three subgroups, namely A (S8 and S32), B (S22, S27, and S31), and C (S37). Accessions S27 and S31 had a high degree of similarity.

“…The floral scent chemistries of non-Philodendron aroid taxa pollinated by cyclocephaline scarab beetles have also been studied. For instance, the floral scent of Taccarum ulei is dominated by two VOCs -2-hydroxy-5-methyl-3-hexanone (76%) and dihydro-β-ionone (20%) (Maia et Madison along a latitudinal gradient of about 2,000 km across the Brazilian states of Maranhão and São Paulo (Gottsberger et al 2020). A second possibility is that the two populations of P.…”

We provide a characterization of the floral scent chemistry of nine species of Philodendron present in French Guiana. The scent samples were obtained by dynamic headspace, in situ in French Guiana, or from plants in the living aroid collection at the Botanical Garden of the University of Brasilia. Overall, we identified 43 volatile organic compounds (VOCs) belonging to the compound classes of monoterpenes, sesquiterpenes, irregular terpenes, benzenoids, aliphatics, jasmone derivatives, and nitrogen-containing compounds. Five of these floral VOCS are new reports for Philodendron. Interestingly, the floral blends in the investigated species were comprised of 3 -22 VOCs; but when considering only major VOCs (≥ 5%), each fragrant blend could be summarized into one up to four constituents. Except for P. acutatum and P. billietiae, whose floral scents were largely dominated (≥ 93%) by 4-vinylanisole, fragrances of the investigated species were dominated (≥ 62%) each by a different VOC (i.e., dehydrojasmone, dihydro-β-ionone, (E)-4,8-dimethylnona-1,3,7-trien-5-yl acetate, methyl benzoate, 1,3,5-trimethoxybenzene, dihydrobovolide, or (Z)-jasmone). Consequently, all floral scent compositions significantly differed from one other. We compare our results to published data to provide an insight into the floral scent chemistry within the genus Philodendron. We further discuss the diversity of VOCs in cyclocephaline scarab-pollinated aroids.
