Silicon, which is widely used in different fields, has been used in plant production in vivo and in vitro studies in recent years. Especially in in vitro studies, it is seen that its effect on plant growth and development has been examined. In this study, the effect of three different silicon sources and their four concentrations on micro-propagation of 140 Ru grape rootstocks was investigated. In the study, as explants one-node micro cuttings of rootstock and MS (Murashige and Skoog) as the nutrient medium were used. 1 mg L -1 BA (Benzyl Adenine) at the stage of obtaining shoots from cuttings and in the rooting stage, 1 mg L -1 IBA (Indole Butyric Acid) were added to the nutrient medium. At both stages, 0 (Control), 0.5, 1.0 and 2.0 mg L -1 doses of potassium, sodium and calcium silicate were added to the nutrient medium. Explant viability and mortality rate, shooting rate, plant length, node number, shoot fresh and dry weight, chlorophyll content (SPAD), root number, root length, root fresh and dry weight were examined to determine the effect of the applications. The variance analysis of the study was carried out according to the Two-Way Completely Randomized Experimental Design. According to the results, among the silicon sources, the highest shooting rate (84.40%) was found in the medium containing sodium silicate. The highest shoot fresh and dry weight (0.178 g and 0.026 g, respectively) and root fresh and dry weight values (0.213 g and 0.023 g, respectively) were obtained from potassium silicate. While the number of roots was 2.98 in the medium containing potassium, it was determined as 2.91 in the medium containing calcium silicate. Media containing 1 mg L -1 silicate was found to be more successful than 0, 05, 2 mg L -1 concentrations. The highest values recorded at the concentration were 4.49 cm in plant length, 7.44 in node number, 0.183 g and 0.028 g in shoot fresh and dry weight, respectively, 28.37 in SPAD value and 3.27 in root number. As a result of the study, it is concluded that adding 1 mg L -1 concentration of potassium, calcium and sodium silicate to the nutrient medium can be used in future studies related with in micro propagation.

“…That's why, the most suitable micro-propagation protocol must be created for every genotype. Recently, it has been observed that studies have been carried out to be increased the success rate by adding different silicon (Si) sources to the nutrient medium in micro-propagation (Martins et al, 2019;Montovani et al, 2020).…”

RESUMO Tillandsia usneoides, conhecida como barba-de-velho, possui importância na medicina popular, com atividade antiviral, antioxidante, hipoglicêmica e antitumoral. Nesse contexto, o objetivo do trabalho foi realizar a caracterização anatômica foliar de T. usneoides, atrelado a testes histoquímicos visando auxiliar na identificação da espécie e subsidiar estudos taxonômicos e farmacológicos. O material vegetal foi coletado em uma área de restinga no norte do Espírito Santo. Para as análises anatômicas foram utilizadas técnicas usuais de anatomia vegetal. Para os testes histoquímicos, foram analisadas as seguintes substâncias: amido, lignina, lipídeos, compostos fenólicos e cristais. Em vista transversal, o limbo apresenta epiderme uniestratificada recoberta por cutícula e presença das células centrais das escamas epidérmicas. Subsequente, a hipoderme é caracterizada por células aclorofiladas, dispostas em uma única camada. O mesofilo é homogêneo, constituído por parênquima clorofiliano, cujas células possuem formato isodiamétrico. As fibras preenchem as extremidades dos feixes vasculares, os quais encontram-se dispersos na região central do mesofilo. Em vista frontal, as células da epiderme possuem parede celular ondulada, estômatos tetracíticos, geralmente recobertos pelas escamas, que são numerosas e distribuídas de forma aleatória ao longo da folha. Dentre os testes histoquímicos analisados, houve apenas reação positiva para lipídeos e os cristais do tipo ráfides possuem composição de oxalato de cálcio. Os caracteres distintivos de T. usneoides são folhas com formato circular, parede celular ondulada das células epidérmicas, estômatos tetracíticos e escamas com séries de quatro, oito e dezesseis células, sendo a ala assimétrica. PALAVRAS-CHAVE: Anatomia da folha, Testes Histoquímicos, Tillandsioideae. LEAF ANATOMY AND HISTOCHEMISTRY OF Tillandsia usneoides (L.) L.

In vitro cultivation is a technique with wide application for micropropagation. However, each species has specific mineral needs for this type of cultivation. The objective was to assess the impacts of the saline solution culture medium on the performance of the photosynthetic apparatus and growth of Bromelia antiacantha during in vitro cultivation, and thus to elucidate the mitigation of the nutritional imbalance that can interfere in the electron transport in the plants. Plants were cultivated in a salt concentration gradient of MS medium (0%, 25%, 50%, 75% or 100%). The growth traits and fluorescence a chlorophyll were analyzed. Intermediate concentrations of MS medium resulted in plants with a larger number of leaves and longer root length. The OJIP curves and results of the JIP test showed that the plants grown without MS salts presented less efficient photosystem II (PSII), as indicated by the performance index [Pi(total)]. In contrast, the intermediate concentrations (MS 25% and 50%) had a positive effect on the performance of the photosynthetic apparatus. The MS 25% medium can be used for in vitro cultivation of B. antiacantha, enabling the development of plants with suitable physiological qualities for planting in the field.
