“…Leaves and the mixture of leaves/berries biomasses (profiles a and c) presented stomata which had elliptical form and remained open all the time. The stomatal type is cyclocytic, which also has been established for Cydonia oblonga Mill [ 31 ] and Amelanchier ovalis Medic [ 32 ], plants belonging to the family Rosaceae . However, the difference in the surface morphology after AF uptake by the three different biomasses is evident in Figure 6 (profiles d, e and f); the surface morphology of the biomaterial became rough, stomata remained closed (profiles d and f) and particle agglomeration occurred.…”

Mycotoxin adsorption onto biomaterials is considered as a promising alternative for decontamination without harmful chemicals. In this research, the adsorption of B-aflatoxins (AFB1 and AFB2) using Pyracantha koidzumii biomasses (leaves, berries and the mixture of leaves/berries) from aqueous solutions was explored. The biosorbent was used at 0.5% (w/v) in samples spiked with 100 ng/mL of B-aflatoxin standards and incubated at 40 °C for up to 24 h. A standard biosorption methodology was employed and aflatoxins were quantified by an immunoaffinity column and UPLC methodologies. The biosorbent-aflatoxin interaction mechanism was investigated from a combination of zeta potential (ζ), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The highest aflatoxin uptakes were 86% and 82% at 6 h using leaves and the mixture of leaves/berries biomasses, respectively. A moderate biosorption of 46% was attained when using berries biomass. From kinetic studies, the biosorption process is described using the first order adsorption model. Evidence from FTIR spectra suggests the participation of hydroxyl, amine, carboxyl, amide, phosphate and ketone groups in the biosorption and the mechanism was proposed to be dominated by the electrostatic interaction between the negatively charged functional groups and the positively charged aflatoxin molecules. Biosorption by P. koidzumii biomasses has been demonstrated to be an alternative to conventional systems for B-aflatoxins removal.

“…It seems clear that the wax amount is not constant within species but rather related to some ecological factors in their habitat. Crystalloid epicuticular waxes and papillae provide additional protection from moisture because of their water proof qualities (Ganeva and Uzunova ).…”

“…Characters of the leaf epidermis have proved useful for the classiﬁcation and identiﬁcation of difﬁcult taxa such as Pinus (Whang et al 2001), basal angiosperms (Carpenter ), Salix (Chen et al , Ghahremaninejad et al ) and Scorzonera hispanica (Chwil et al 2015). Regarding Rosaceae, studies have been conducted on some genera: Rosa (Wissemann ), Cydonia (Ganeva ), Crataegus (Ganeva et al ), Malus (Ganeva and Uzunova ), Amelanchier (Ganeva and Uzunova ), Sibbaldia (Tahir and Rajput ) and Pyrus (Zamani et al 2017). Also in these genera have some such characters, e.g.…”

In this study, micromorphological features of the leaf epidermal cells of 17 species of Iranian Cotoneaster were determined. The studied species were compared with each other and with phylogenetic relationships established by previous studies. Three populations of C. integerrimus and C. multiflorus were studied as representatives of C. subgen. Cotoneaster and Chaenopetalum, respectively. To evaluate quantitative and qualitative characters, multiple correspondence analysis (MCA) and factor analysis of mixed data (FAMD) were performed. Finally, relationships among the taxa were illustrated by hierarchical clustering analysis. Three stomatal types were identified, i.e. anomocytic, stephanocytic and actino‐stephanocytic. The wax and cuticle density was higher in species from semi‐moist habitats than in those from dry and semi‐dry habitats. The patterns formed by the anticlinal walls of the epidermal cells were sinuous, repand and straight‐curved. Interestingly, there was a significant relationship between the length of leaves, the density of the indumentum and the pattern formed by the anticlinal cell walls. The leaves of species with large leaves also have lower hair density and more curved anticlinal cell walls. It appears probable that climatic conditions affected the evolution of leaf micro‐morphological characters during the early diversification of the genus, but that these characters have subsequently been permanently fixed by phylogenetic constraints and thus appear diagnostic for extant species.

“…Natural tree heights can range from 1.5 to 3 m, and primary soft wood is covered with hair that turns brown as it develops. The leaves can be 2 to 7 cm long; they are ovate and serrate, with trichomes on the abaxial side when young [28]. A. ovalis in Greece is in flower from April through June depending on region, aspect, and altitude, showing impressive inflorescences of small hermaphrodite flowers with white petals.…”

The snowy Mespilus, or serviceberry (Amelanchier ovalis Medik., Rosaceae) represents a neglected and underutilized small fruit tree species with high nutritional value. In this work, we present the results of a long-term study facilitating the sustainable exploitation of A. ovalis as a new germplasm resource from the Greek flora. Ten wild-growing population samples of A. ovalis have been collected from natural habitats in northern Greece. Asexual propagation trials on these materials delivered successful propagation (83.3% rooting) on a selected genotype via leafy cuttings of young, primary, non-lignified soft wood with the application of the rooting hormone. The ex situ cultivation potential of the selected genotype has been evaluated under distinct fertilization regimes in a pilot field trial. Three-year results of this ongoing trial have shown that A. ovalis does not require external nutrient enhancement to be established during its early stages since plant growth rates between conventional fertilization and control plants were similar for the first two years and higher compared to organic fertilization. Conventional fertilization delivered higher fresh fruit production in the third year, with higher fruit number and fruit size compared to organic fertilization and control plants. The phytochemical potential of the cultivated genotype was assessed via the total phenolic content and radical scavenging activity of separate extracts from leaves, twigs, flowers, and young fruits, which revealed that individual plant organs have strong antioxidant activity despite their moderate total phenolic content. The multifaceted approach applied herein has provided novel data that may set the framework for further applied research toward the sustainable agronomic exploitation of Greek A. ovalis as a diversified superfood crop.
