Data_Sheet_1_Systematic Investigation of the Effects of Seven Plant Extracts on the Physiological Parameters, Yield, and Nutritional Quality of Radish (Raphanus sativus var. sativus).ZIP

The modern agricultural sector faces the challenge of addressing the needs of the fast-growing global population. This process should be both high-yielding and sustainable, without creating risks for the environment and human health. Therefore, natural products are gaining attention in the production of safe and nutritious food. In a systematic effort to develop affordable and effective biostimulants, we examined the impact of botanical extracts on the growth and physiological parameters of radish plants under field conditions. Ultrasound-assisted extraction, mechanical homogenization, and water were used for the production of potential plant-based biostimulants. Foliar applications of the bio-products, developed and used in our study, have led to an increase in the examined parameters (total yield, dry weight, photosynthetic pigments, vitamin C, nitrates, and micro- and macroelements). A decrease in the total phenolic compounds content was also noted, as well as a varied impact on the steam volatile compounds, fatty acids, sterol, and glucosinolates composition. The most beneficial effects on radish, in terms of physiological and biochemical properties, were found in groups treated with extracts based on the common dandelion, valerian, and giant goldenrod. This innovative approach presented in our study could provide a valuable tool for sustainable horticultural production.

现代农业产业在满足快速增长的全球人口需求方面面临着挑战。这一过程应当既高产又可持续，同时避免对环境和人类健康造成风险。因此，天然产品在安全营养食品的生产中受到了越来越多的关注。为了系统地开发经济实惠且有效的生物刺激剂，我们研究了在田间条件下，植物提取物对萝卜植株生长和生理参数的影响。本研究中，我们使用了超声波辅助提取、机械均质化和水来生产潜在的植物基生物刺激剂。在叶片上应用本研究中开发并使用的生物产品，导致所考察的参数（总产量、干重、光合色素、维生素C、硝酸盐以及微量和宏量元素）有所增加。同时，总酚类化合物含量也出现下降，对蒸汽挥发性化合物、脂肪酸、甾醇和硫代葡萄糖苷的组成产生了不同的影响。在生理和生化特性方面，以常见蒲公英、缬草和巨金杆提取物为基础处理的组别对萝卜的影响最为显著。本研究中提出的创新方法，可以为可持续园艺生产提供一项宝贵的工具。
