“…There was no clear separation of both Pinus species and their provenances based on the n ‐alkane concentrations. A similar lack of ability of n ‐alkanes (five selected n ‐alkanes) to distinguish P. heldreichii and P. peuce from the Scardo‐Pindic Mountains was observed by Nikolić et al [24–25] . Nevertheless, chemotaxonomic usefulness of n ‐alkanes was found by Maffei et al [34] .…”

“…[17] According to Bush and McInerney [18] and Diefendorf et al, [19] the composition of this layer is highly variable and, for that reason, has high chemotaxonomic potential. Among these epicuticular compounds, n-alkanes are the most widely used ones, for example as markers to assess the grazing behavior of both domestic and wild herbivores, [20][21] but also in chemotaxonomy studies to differentiate conifers of different geographical locations and/or identification of intraspecific taxa of Pinus, [22][23][24][25][26] Picea [27] and Juniperus [28][29] species. Results obtained by Le Provost et al [30] showed a higher cuticular wax content in non-irrigated young saplings of P. pinaster compared to irrigated ones.…”

n‐Alkane and long‐chain alcohol (LCOH) profiles of needle cuticular waxes of nine provenances of three Pinus species (P. taeda. P. pinaster and P. pinea) were determined and their chemotaxonomic importance was studied. n‐Alkanes concentrations were very low in all Pinus spp. A lack of ability of these compounds to differentiate Pinus spp. and their provenances was observed. LCOH concentrations were much higher, being nonacosan‐10‐ol (10‐C29‐OH) the most abundant one in all Pinus spp. Total LCOH concentrations varied (P<0.001) between Pinus spp. with P. taeda presenting the highest (P<0.05) value and P. pinea the lowest one. Differences in LCOH profiles were large (P<0.001) and allowed separation of Pinus spp. in the Principal Component Analysis (PCA). Although a noticeable separation of individuals was not observed. cluster analysis on LCOH concentrations allowed a clear distinction between species, indicating their potential to be used as chemotaxonomic markers to differentiate provenances of different Pinus spp.

“…In addition to having high Young’s modulus and ultimate stress, adulose is also superhydrophobic, which enables its use as a packaging material in many different applications. The additives used in the formation of adulose are plant-derived wax [ 17 , 18 ], which when combined with cellulose makes this composite to be a completely biomaterial-based sustainable packaging material.…”

This article focuses on the study related to the estimation of packaging material properties of cellulose–wax nanocomposite using molecular dynamics simulation (MDS). Cellulose based packaging material is gaining lot of importance due to its good material properties and low cost. Cellulose with small amount of plant-derived wax (nonacosane-10-ol and nonacosane-5,10-diol) offers higher mechanical strength and modulus of elasticity compared to the conventional synthetic polymer materials. In this article, in addition to the estimation of mechanical properties, the thermal stability of the proposed ecofriendly cellulose–wax composite is evaluated by estimating the glass transition temperature which essentially provides critical information on the glassy state and rubbery state of this biopolymer. The glass transition temperature of this composite changes significantly compared to that of pure cellulose (which also suffers from poor mechanical strength). Transport properties such as diffusion volume and diffusion coefficient of oxygen, nitrogen, and water are estimated using the results obtained from MDS. The diffusion coefficients of these species within the cellulose–wax composite are analyzed using the diffusion volume and interaction energies of these constituents with the wax and cellulose.

The cuticle is important in the interaction between the plant and its environment, especially in the dry areas. Four species of junipers from the section Sabina wild growing in the Balkans were selected to study leaf wax composition using GC/MS and GC‐FID and its surface morphology under SEM to understand the correlation between the distribution and/or habitat of these species and their cuticles. SEM micrographs showed continuous, smooth epicuticular layers with crusts in all species but with a species‐specific distribution of different 3D crystalloid types and different cuticle thickness. n‐C33 alkane was the most abundant compound, followed by n‐C29, n‐C31, and n‐C35, depending on the species and the site. The average chain length (N) was the lowest in J. phoenicea, but with the greatest dispersion around it. At the same time, the two most continental species (J. foetidissima and J. excelsa) show the N with the lowest dispersion around it. The statistical analyses confirmed the significance of climate on the evolution of the specific epicuticular wax composition in studied junipers.
