“…High CR mass in spring in both LOM and HOM soils suggest relation between E. coccineum growth season with cluster root development. This finding could be related with phytohormone induction of CR because auxin, a principal inductor of CR studied (Gilbert et al, 2000;Skene and James, 2000;Casimiro et al, 2001;Ljung et al, 2001;López-Bucio et al, 2005), is synthesized and transported in a period of growth of the plants (Schrader et al, 2003;Yörük et al, 2005;Nagar and Sood, 2006). Nevertheless, further studies are needed to reveal possible changes in auxin levels and transport during the growing season and its effect in the induction of CR in E. coccineum.…”

Embothrium coccineum J.R. Forst. & G. Forst. (Proteaceae) is a tree that grows successfully in nutrient poor soils of southern Chile at full sunlight. Under these conditions it develops cluster roots (CR). However, the induction of CR on this species has not been studied completely. The aim of this work was to study the effect of seasonality, soil and weeds in the development of CR in E. coccineum. The present study was performed in Los Lagos Region (41º72' S lat), Chile. Plants of E. coccineum were grown in sandy soils in presence or absence of weeds, using two concentrations of organic matter. The number of CR per plant, CR mass and P concentration in leaves was measured during the four seasons in E. coccineum plants. The CR development in the soil with high organic matter concentration and without weeds was observed in autumn, spring and summer, and in the soil with low organic matter concentration was observed in autumn, winter and spring. Not found related of this result with the foliar P concentration in E. coccineum. The results suggest a strong seasonal and weeds effect on CR development in E. coccineum under field conditions.

“…The use of Lp as a proxy for kH is another limitation that could be addressed to refine the model, as well as more localized measurements like fine rooting. The lack of hormone measurements was partially overcome by the inclusion of an empirical equation fitting seasonal patterns of GAs previously studied in woody species and grapevines ( Kopcewicz, 1968 ; Yörük et al., 2004 ; Acheampong et al., 2015 ). This methodology is widely accepted in modelling, since many parameters that are difficult to assess in situ , are often adopted from bibliography, especially in biological/molecular subjects ( Magni and Saparcino, 2014 ; Cobelli and Carson, 2019 ).…”

“…An empirical fit of the purported concentrations of bioactive GAs was calculated, based on the seasonal dynamics of some species ( Kopcewicz, 1968 ; Yörük et al., 2004 ) and the measured values of leaves and buds of grapevines ( Acheampong et al., 2015 ). The equation fit is:

where a: 22.27; b: 27.44; c: -1901; and time is days of a growing season.…”

Mechanistic modeling constitutes a powerful tool to unravel complex biological phenomena. This study describes the construction of a mechanistic, dynamic model for grapevine plant growth and canopy biomass (vigor). To parametrize and validate the model, the progeny from a cross of Ramsey ( Vitis champinii ) × Riparia Gloire ( V. riparia ) was evaluated. Plants with different vigor were grown in a greenhouse during the summer of 2014 and 2015. One set of plants was grafted with Cabernet Sauvignon. Shoot growth rate (b), leaf area (LA), dry biomass, whole plant and root specific hydraulic conductance (k H and L pr ), stomatal conductance (g s ), and water potential (Ψ) were measured. Partitioning indices and specific leaf area (SLA) were calculated. The model includes an empirical fit of a purported seasonal pattern of bioactive GAs based on published seasonal evolutionary levels and reference values. The model provided a good fit of the experimental data, with R = 0.85. Simulation of single trait variations defined the individual effect of each variable on vigor determination. The model predicts, with acceptable accuracy, the vigor of a young plant through the measurement of L pr and SLA. The model also permits further understanding of the functional traits that govern vigor, and, ultimately, could be considered useful for growers, breeders and those studying climate change.

“…Although previous studies report lower values of vitamin C content in R. canina, this aspect might be due to variations in the analytic techniques, fruit development stage under examination, environmental factors, geographic origin, and genetic variability (Ercisli, 2007;Nojavan et al, 2008;Demir et al, 2014;Nađpal et al, 2016). The geographic origin is another important factor in (Yoruk et al, 2008). The present section highlighted the significant variation in vitamin C content among different species of rosehips, with R. rugosa and R. canina fruits showing the highest concentration, strongly dependent on geographic origin and harvesting period.…”

Rosa spp., commonly known as rosehips, are wild plants that have traditionally been employed as herbal remedies for the treatment of a wide range of disorders. Rosehip is a storehouse of vitamins, including A, B complex, C, and E. Among phytonutrients, vitamin C is found in the highest amount. As rosehips contain significant levels of vitamin C, they are perfect candidates for the development of skincare formulations that can be effectively used in the treatment of different skin disorders (i.e., scarring, anti-aging, hyperpigmentation, wrinkles, melasma, and atopic dermatitis). This research focuses on the vitamin C content of several Rosa sp. by their botanical and geographic origins, which according to research studies are in the following order: R. rugosa > R. montana > R. canina > R. dumalis, with lower levels in R. villosa and R. arvensis, respectively. Among rosehip species, R. canina is the most extensively studied species which also displays significant amounts of bioactive compounds, but also antioxidant, and antimicrobial activities (e.g., against Propionibacterium acnes, Staphylococcus aureus, S, epidermis, and S. haemolyticus). The investigation also highlights the use of rosehip extracts and oils to minimise the harmful effects of acne, which primarily affects teenagers in terms of their physical appearance (e.g., scarring, hyperpigmentation, imperfections), as well as their moral character (e.g., low self-confidence, bullying). Additionally, for higher vitamin C content from various rosehip species, the traditional (i.e., infusion, maceration, Soxhlet extraction) and contemporary extraction methods (i.e., supercritical fluid extraction, microwave-assisted, ultrasonic-assisted, and enzyme-assisted extractions) are highlighted, finally choosing the best extraction method for increased bioactive compounds, with emphasis on vitamin C content. Consequently, the current research focuses on assessing the potential of rosehip extracts as medicinal agents against various skin conditions, and the use of rosehip concentrations in skincare formulations (such as toner, serum, lotion, and sunscreen). Up-to-date studies have revealed that rosehip extracts are perfect candidates as topical application products in the form of nanoemulsions. Extensive in vivo studies have revealed that rosehip extracts also exhibit specific activities against multiple skin disorders (i.e., wound healing, collagen synthesis, atopic dermatitis, melasma, and anti-aging effects). Overall, with multiple dermatological actions and efficacies, rosehip extracts and oils are promising agents that require a thorough investigation of their functioning processes to enable their safe use in the skincare industry.
