“…We observed both palisade and spongy parenchyma have three layers, while upper and lower epidermis have only one layer. Pinto et al (2011) were investigated the Castanea sativa leaves and they had observed the upper epidermis as two layers and lower epidermis as a single layer. We observed upper and lower epidermis has only one layer [21] Pehlivan (1995) and Paldat (2015) confirmed that the pollen morphologies of Castanea sativa are essentially the same [22,23].…”

B u çalışma ile Türkiye propolisi için bitkisel bir köken olan Castanea sativa'nın anatomik ve palinolojik karakterlerinin araştırılması amaçlanmıştır. Bu kapsamda, Castanea sativa bitkisinin yaprak ve gövde enine kesitleri incelenmiştir. Mikroskobik inceleme ile yaprak enine kesitinde palizat ve sünger parenkiması, üst ve alt epidermis, sklerenkima ve iletim demetleri gözlenmiştir. Gövde enine kesitinde ise periderm, sklerenkimatik doku, sekonder ksilem, sekonder floem, vaskular kambiyum ve parenkimatik öz gözlenmiştir. Palinolojik analiz ile polenin radyal simetrik, izopolar ve trikolporat olduğu belirtilmiştir. Mikroskobik analizlerin yanında, Castanea sativa propolisinin kimyasal içeriği gaz kromatografisi ve kütle spektrometresi (GC-MS) cihazı ile analiz edilmiştir. Propolisin etanol özütünün kimyasal analizi ile alkoller, aldehidler, alifatik asit ve esterleri, karboksilik asit ve esterleri, sinamik asit ve esterleri, flavonoidler, hidrokarbonlar ve ketonlar grubuna ait bileşikler tespit edilmiştir. "Benzoik asit" bileşiği %7.88'lik oranla özütte en yüksek miktarda bulunan bileşiktir. Bu çalışmanın anatomik, palinolojik ve kimyasal analiz sonuçları Türkiye arıcılığı ve arı ürünleri ile ilgili ileriki çalışmalara ışık tutacaktır.

“…This trait helps to decrease water loss caused by transpiration because a small surface area allows leaves to avoid overheating by remaining close to ambient air temperature [4]. Differences in leaf size have been described in plants under contrasting light conditions, such as sun and shade environments or even in leaves occupying different regions in the canopy [28][29][30]. Thus, given the high luminosity condition in both environments, it was expected to find leaves with similar size or even bigger size in plants from TU (once they coexist with trees around).…”

This study aimed to investigate the leaf anatomy of Jacquinia armillaris plants in two different Venezuelan xeric shrublands to evaluate possible variations caused by the environments, which differ in rainfall and soil salinity. Leaf samples were collected in two sites: La Tortuga Island, a dryer and salty environment than the other collecting site, Turpialito, a coastal location in the mainland. The epidermis and the mesophylls were observed with a light microscope and measured with an ocular micrometer inserted in one of the eyepieces. The results show that J. armillaris has many characteristic anatomical traits of xerophytes, among them: thick cuticles and thick epidermis in both leaf surfaces, stomata only in the abaxial side and epidermal depressions lodging a glandular trichome. Leaves are bifacial and present multistratified palisade parenchyma facing the adaxial epidermis and abaxial spongy parenchyma with abundant intercellular spaces. Furthermore, the hypodermis is composed of one or two cell layers below the upper epidermis. Leaf lamina dimension, petiole, cuticles, epidermis and hypodermis cells, as well as the stomatal occlusive cells and number of trichomes, had differences in size and number when the plants of both sites were compared, being higher in plants from La Tortuga. On the other hand, palisade parenchyma and stomatal density were higher in Turpialito plants. Plants collected in La Tortuga Island showed characteristics that suggest adaptation to the island's saline and more arid conditions in comparison to plants from Turpialito, which presented more leaf traits related to adaptations to water deficit. These results demonstrate the phenotypic plasticity of J. armillaris plants that grow in two different xeric shrublands.

“…It is surrounded by an outer protective tissue, the epidermis, with stomata fundamentally present in the lower epidermis surface. The mesophyll is heterogeneous and asymmetric due to the presence of a palisade parenchyma in the upper surface, characterized by rod-shaped cells with a lot of chloroplasts and a few intercellular air spaces, and a spongy parenchyma in the lower surface, characterized by isodiametric cells with an irregular contour and wide lacunas [68]. In the mesophyll, it is still possible to find a vascular system, composed of xylem (where water and minerals are transported) and phloem (where organic substances formed during photosynthesis are transported), and mechanical support tissues [62].…”

Traditionally, tea, a beverage made from the processed leaves of the tea plant, Camellia sinensis, and herbal infusions have been primarily consumed for their pleasant taste. Nowadays, they are also consumed because they contain nutraceutical compounds, such as polyphenols. Grapes and grape/wine sub-products such as non-fermented/semi-fermented or fermented grapes, skins, and seeds are a rich source of health-promoting compounds, presenting a great potential for the development of new beverages. Therefore, these grape/wine sub-products are used in the beverage sector for the preparation of infusions, tisanes, and decoctions. Besides polyphenols, fermented grapes, skins, and seeds, usually discarded as waste, are enriched with other health-promoting/nutraceutical compounds, such as melatonin, glutathione, and trehalose, among others, which are produced by yeasts during alcoholic fermentation. In this review, we summarize the benefits of drinking herbal infusions and discuss the potential application of some grapevine fermentation waste products in the production of healthy beverages that we can call grape infusions.
