Nectary structure of Cotoneaster roseus
Cotoneasters are widely planted as ornamentals, which at the same time can serve as a sources of nectar for honey bees and bumble bees. The present study gives a detailed description of the nectary anatomy of Cotoneaster roseus. The floral nectary is located within the receptacle, with well distinguishable regions of the epidermis, glandular tissue and nectary parenchyma. Modified nectary stomata are at level with or below the epidermis; the glandular cells are arranged in 3 to 4 subepidermal layers; and calcium oxalate crystals are typical in the nectary parenchyma. Data are provided on the size and thickness of the nectar gland, which can be significant factors determining the nectar producing ability of the flowers

Landscape Indicators in Rural Development
Landscape values and landscape potential are the base of rural development. Long-term and balanced utilization of these is possible through sustainable landscape management. The Hungarian rural regions have very diverse characteristics, that is why properly targeted and specified programs, strategies are needed to develop them in an appropriate way.
Several planners, researchers and authors emphasized that the first step of sustainable landscape management is landscape-function analysis (De Groot et al., 2010; Herman et al., 2014). Before clustering and typification of rural regions based on the levels of the different landscape functions, it is very important to explore the potential relationships, regularities among these functions

Green Infrastructure in Rural Development, Case Study in Hungary
Green infrastructure (GI) planning as a complex, multifunctional tool is appropriate to realize objectives related to nature conservation, rural development, and sustainable agriculture. In a rural region of Hungary, we carried out a project covering wide range of activities: elaboration of new reservoirs, habitat rehabilitation enhancing the ecological stability of the Koppány-creek and suggestions for the improvement of the sustainability and multifunctionality of agricultural production. The pilot area is situated in Koppány Valley that is a hilly landscape rich in natural values located south of the popular tourist destination Lake Balaton and is affected by extreme aging and emigration processes. A rural development association emerged in the region to establish the Koppány Valley Nature Park. The association aims to develop innovative, sustainable tourism services based on natural values, to develop active recreational facilities, to strengthen local economy, and particularly to promote the diversification of agriculture and to create the social, economic and environmental sustainability of agricultural production. We elaborated a complex revitalization program in the frames of green infrastructure projects. Our green infrastructure development plan aims to develop the Koppány Valley natural capital: to increase the biodiversity and enrich the landscape.
The green infrastructure project had the following objectives:
⎯ Elaboration of a complex analysis including economic, social and ecologic conditions,
⎯ Assessment of water management in the creek valley,
⎯ Assessment of functionality and connectivity of ecologic network,
⎯ Elaboration of a strategy for enhancing the ecologic value of the riparian vegetation and the surrounding landscape.
⎯ Elaboration of tourism development proposals based on the enhanced ecologic value of the region
