Abiotic stress conditions, such as salinity, affect plant development and productivity and threaten the sustainability of agricultural production. Salt has been proven to accumulate in soil and water over time as a result of various anthropogenic activities and climatic changes. Species of the genus thrive in the most saline environments and have a wide climatic tolerance. They can be found in a variety of subtropical, oceanic, and continental environments. This study aims to establish as a novel source of plant-based compounds that can grow in areas unsuitable for other crops. The morphological and compositional changes in the tissues of in different consecutive developmental stages have not been investigated so far. Therefore, a comprehensive study of changes during the lifecycle of was carried out, following changes in the plant's composition, including biomass yield, and soluble and insoluble compounds. For this, plants were cultivated in hydroponics for 15 weeks and harvested weekly to analyze biomass production, to determine soluble and insoluble compounds, protein content, and polyphenols. According to the results, glucan, xylan, and lignin increase with plant age, while water extractives decrease. Protein content is higher in young plants, while flavonoid content depends on the phenological stage, decreasing in the early flowering stage and then increasing as plants enter early senescence. Our results can aid in finding the optimal harvesting stage of depending on the component of interest.
非生物胁迫条件，如盐度，会影响植物的发育和生产力，并威胁到农业生产的可持续性。由于各种人为活动和气候变化，盐已被证明会随着时间的推移在土壤和水中积累。该属的物种在盐度最高的环境中生长良好，并且具有广泛的气候耐受性。它们可以在各种亚热带、海洋和大陆环境中找到。本研究旨在将其确立为一种新型的植物源化合物来源，这种化合物能够在不适宜其他作物生长的地区生长。到目前为止，尚未对该植物在不同连续发育阶段的组织形态和成分变化进行研究。因此，对该植物生命周期中的变化进行了全面研究，跟踪了植物成分的变化，包括生物量产量以及可溶性和不溶性化合物。为此，将植物在水培条件下培养15周，并每周收获一次，以分析生物量产量，测定可溶性和不溶性化合物、蛋白质含量和多酚含量。根据结果，葡聚糖、木聚糖和木质素随植物年龄增长而增加，而水提取物则减少。幼嫩植物中的蛋白质含量较高，而黄酮类化合物的含量取决于物候阶段，在初花期减少，然后随着植物进入早期衰老阶段而增加。我们的结果有助于根据感兴趣的成分找到该植物的最佳收获阶段。
