Urban green areas can play a crucial role in establishing spaces that are valuable for pollinators. However, to help ‘pollinator-friendly’ management of urban areas, complete information on the quantity and quality of available floral reward is needed. In this paper, the nectar and pollen of six Cotoneaster species (Rosaceae) were investigated in a two-year experiment established in Lublin city, SE Poland. In temperate climate, Cotoneaster species can ensure nectar and pollen in the full spring period (May/early June) or in early summer (June). A single species can support pollinators on average for 22.9 days. Flowers of Cotoneaster species produce high quantities of nectar (2.27–9.48 mg per flower) and low amounts of pollen (0.11–0.33 mg per flower). On average, the total sugar yield in Cotoneaster species was 11.5 g/m² (2.3–22.2 g/m²), whereas the total pollen yield was 1.3 g/m² (0.8–2.8 g/m²). Due to the high potential for total sugar yield, C. macrophyllus, C. lucidus, and C. horizontalis should be recommended to optimize the management of food resources in urban areas. Honeybee was the main insect visitor (70.1 % of the total number of visitors); therefore, Cotoneaster species can be considered valuable for urban beekeepers. However, conservation schemes for bumblebees (21.3 % of the total number of visitors) might also benefit from arrangements with these shrubs. Nevertheless, considering Cotoneaster species in conservation protocols, good-yielding pollen plants should be introduced to compensate for insufficient nutrient intake from pollen in spring.

城市绿地可以在建立对传粉媒介有价值的空间方面发挥关键作用。然而，为了帮助城市地区的“传粉媒介友好型”管理，需要有关可用花卉奖励的数量和质量的完整信息。在本文中，在波兰东南部卢布林市开展的为期两年的实验中研究了六种枸子（蔷薇科）的花蜜和花粉。在温带气候下，栀子树种可以在整个春季（五月/六月初）或初夏（六月）确保花蜜和花粉。单个物种平均可以支持传粉媒介 22.9 天。栀子花_物种产生大量的花蜜（每朵花 2.27-9.48 毫克）和少量的花粉（每朵花 0.11-0.33 毫克）。平均而言，枸子的总糖产量为11.5 g/m ² (2.3–22.2 g/m ² )，而总花粉产量为 1.3 g/m ² (0.8–2.8 g/m ² )。由于总糖产量潜力巨大，应推荐大叶茯苓、灵芝和水平茯苓，以优化城市地区的粮食资源管理。蜜蜂是主要的昆虫游客（占游客总数的 70.1%）；因此，枸子对于城市养蜂人来说，物种可以被认为是有价值的。然而，大黄蜂保护计划（占游客总数的 21.3%）也可能受益于这些灌木的安排。尽管如此，考虑到保护协议中的枸子属植物，应引入高产花粉植物以弥补春季花粉营养摄入不足。
