“…For instance, Zucker et al () found that removal of petal pigments by antisense suppression of the flavanone 3‐hydroxylase gene in the anthocyanin biosynthetic pathway led to higher emission of an aromatic volatile in Dianthus caryophyllus L. Generally, different flower color morphs in polymorphic plants show different floral scent profiles (Zucker et al, ; Majetic et al, ; Salzmann & Schiestl, ; Delle‐Vedove et al, ). Some researchers predict that flower color and scent association will be an interesting theme in pollination ecology because the understanding of relationships between floral colors and floral scents is still in its infancy (Majetic et al, ; Rausher, ; Schaefer & Ruxton, ; Dormont et al, ; Wang et al, ).…”

“…For instance, Zucker et al (2002) found that removal of petal pigments by antisense suppression of the flavanone 3hydroxylase gene in the anthocyanin biosynthetic pathway led to higher emission of an aromatic volatile in Dianthus caryophyllus L. Generally, different flower color morphs in polymorphic plants show different floral scent profiles (Zucker et al, 2002;Majetic et al, 2007;Salzmann & Schiestl, 2007;Delle-Vedove et al, 2011). Some researchers predict that flower color and scent association will be an interesting theme in pollination ecology because the understanding of relationships between floral colors and floral scents is still in its infancy (Majetic et al, 2008;Rausher, 2008;Schaefer & Ruxton, 2009;Dormont et al, 2010;Wang et al, 2013). Given that volatile benzenoid compounds and anthocyaninderived pigments originate from the same phenylpropanoid biosynthetic pathway (Zucker et al, 2002;Majetic et al, 2007), our results support the viewpoint that floral color and floral scent have associations because of their similarity in "biosynthetic pathways".…”

In this study, floral color, scent composition and emission rate, nectar property, pollinators, and breeding system of dimorphic Buddleja delavayi Gagnep. were investigated. Flower color of B. delavayi was determined using a standard color chart and spectrophotometer, and two distinct color polymorphisms were observed having purple or white flowers. Floral scents of B. delavayi were collected using dynamic headspace adsorption and identified with coupled gas chromatography and mass spectrometry. In total, 28 compounds were identified from the flowers of B. delavayi. The identified scents were divided into three chemical classes based on their biosynthetic origin: terpenes, fatty acid derivatives, and benzenoids. The scent profiles in all individuals were dominated by a few components, such as lilac aldehyde and alcohol, 4‐oxoisophorone, benaldehyde, and oxoisophorone oxide. Floral scent composition (benzenoids and terpenes) showed a significant difference between white and purple flower morphs. Flower color–flower scent associations in B. delavayi were identified with two distinct scent profiles in the two color phenotypes. The studies of other floral characteristics (nectar, floral visitors, breeding system, and fruit set) indicated that floral scent emission rate, nectar volume, visitor visitation frequency, and natural fruit set were not significantly different between the two flower color morphs. Bagging experiments revealed that seed production of B. delavayi is dependent mainly on honeybee Apis cerana. Lastly, this study implies that dimorphic floral color in B. delavayi may have been maintained by floral visitors and nectar guide color.

“…flowers. [10] Further, in this investigation, the methanolic extracts were used because Shalaby and Shanab [49] have shown that methanol extracts of Spirulina platensis possessed the higher ABTS antioxidant activity compared to the aqueous ones. Total antioxidant capacity of plant extracts, expressed as Trolox equivalent antioxidant capacity (TEAC), was ranged from 49.9 to 184.4 μmol Trolox/g of dry weight ( Table 3).…”

This study was aimed at investigating the phytochemical composition and antioxidant capacity of rhizomes, above‐ground vegetative parts and flowers of three Iris species: Iris humilis Georgi, Iris pumila L. and Iris variegata L. UHPLC‐Orbitrap MS analysis was used for determination of phytochemical profile. Total pigments, phenolics, flavonoids, soluble sugars and starch content as well as ABTS antioxidant capacity were also determined. In total, 52 phenolics compounds were identified with 9 compounds (derivatives of iriflophenone, apigenin C‐glycosides, luteolin O‐glycoside, isoflavones derivatives of iristectorigenin, dichotomitin, nigracin and irilone) never reported before in Iris spp. Differences in phenolic composition profile, pigments, soluble sugar, starch, total phenolics and flavonoids content and total antioxidant capacity were found among Iris species and different part of plants. Significant correlation between total phenolic content and antioxidant capacity was determined. The obtained results are comparable with those obtained for medical plants. These findings could be useful for fingerprinting characterization of Iris species and estimation of possible use in pharmaceutical industries.

“…However, recently it was suggested that intraspecific variation in floral traits may also reflect multiple and conflicting selection pressures. Herbivores or local abiotic conditions may also act directly or indirectly, through pleiotropic effects, as selective agents (Warren and MacKenzie 2001;Schemske and Bierzychudek 2007;Coberly and Rausher 2008;Wang et al 2013). The relative role of these factors on floral polymorphism maintenance is still being debated as their importance as selective agents seems to vary among plant species.…”

How floral polymorphism of flowering plants can be maintained in evolutionary time has long intrigued ecologists and is still debated. In particular, how floral colour polymorphism influences reproductive success is still poorly understood. Here, we investigated the case of Orchis mascula, a deceptive orchid species in which the presence of rare white-flowered individuals is known to increase the percentage pollination of co-occurring coloured morphs. In a brief review, we report all the orchid species for which rare colour morphs are recorded and show that colour polymorphism occurs in most orchid genera occurring in France. In this study, more than 20,000 individuals of O. mascula were surveyed and some rare clear pink morphs were recorded. The frequencies of white-flowered and clear pink-flowered individuals were 0.59% and 0.28%, respectively. These two rare-colour flowered individuals were not randomly distributed and restricted to a few populations. In addition, the presence of pink-flowered individuals and the use of experimental pink lures resulted in an increase in the percentage pollination of surrounding purple-flowered individuals, as previously shown for white-flowered individuals and white lures. These new observations favour kin selection as the means by which floral colour polymorphism is maintained in this species. We suggest conducting comparative studies of other species in order to evaluate the importance of this mechanism in orchid pollination and that of other plant families.
