Determination of Pollen Fertility of Some Cut Rose Varieties in Different Periods
In rose breeding by hybridization, the viable pollen and germination rate of the male parent increases the rate of successful pollination. Therefore, a good variety of pollinators is always needed in hybridization studies.

Ants contribute to raspberry pollination in protected cropping systems
Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Factors Influencing Date Pollen Viability
Pollen of seven date cultivars was stored at 4.5 -5.0'C using desiccator with or without silica gel and in vials outside the desicator as a control. Germination percentage was determined microscopically with a hemacytometer after harvest and at three and

Abstract This article explores the ways in which ‘forest school’, an educational approach where children engage in creative and play based activities in a ‘natural’ environment, can contribute towards Sustainable Development Goal 15 (SDG 15) by promoting sustainable use of terrestrial ecosystems and by helping address biodiversity loss. Drawing on data
