Botanical gardens are collections of plants cultivated in a closed space to be utilized for scientific inquiry, recreation, conservation, botanical and horticultural education and also for public landscape aesthetics. Due to their richness in plant diversity and also their facilities, botanical gardens can have remarkable roles in agricultural studies and plant sciences. In addition, botanical gardens are very important regarding to their roles in creating green space in urban spaces, tourist attractions, economical objects and well-being aspects of peoples. Accordingly, in this study, the roles of botanical gardens were reviewed regarding to biodiversity and genetic studies, seed science, plant protection, soil and water researches, ecological evaluation, climate change, research and educations. These topics were also discussed regarding to their usage in agriculture and plant science studies. Furthermore, some scientific potentials of botanical gardens for future studies have been also taken into account.

植物园是在封闭空间内种植的植物集合，用于科学探究、娱乐、保护、植物和园艺教育以及公共景观美学。由于植物多样性及其设施的丰富性，植物园可以在农业研究和植物科学中发挥重要作用。此外，植物园在创造城市空间、旅游景点、经济物品和人民福祉方面的绿色空间方面发挥着非常重要的作用。因此，本研究回顾了植物园在生物多样性和遗传研究、种子科学、植物保护、水土研究、生态评价、气候变化、研究和教育等方面的作用。这些主题还讨论了它们在农业和植物科学研究中的用途。此外，还考虑了植物园未来研究的一些科学潜力。
