People and Nature, EarlyView.Abstract The decline in biodiversity, particularly in agricultural landscapes, is a pressing global challenge. Monitoring is vital to assess biodiversity trends and conservation effectiveness, yet farmland remains underinvestigated. Engaging farmers and encouraging naturalists to take on new roles could help expand monitoring efforts and strengthen ...

Germination and storage of pollen
Germination of pear pollen markedly improved when boric acid was added to the medium. The pollen was more sensitive to boron in water than in 10 % sugar solution. Supplying weak solutions of boron to pear branches before flowering resulted in a good germination of the pollen in sugar solution without boron.

Long-Term Storage of Raspberry Pollen
Journal of the American Pomological Society, 1983 Plant breeders are sometimes faced with the necessity of storing pollen for extended periods of time. When pollen is stored in such standard facilities as a refrigerator or home freezer, it remains viable for only a few weeks at best. The development of a reliable method to store pollen for extended periods would facilitate crosses among plant with ...

Aspects of Orchid Conservation: Seed and Pollen Storage and their Value in Re-introduction Projects
, 2015 Dry seeds of many orchid species, when stored at low temperatures, are capable of maintaining high levels of viability for many years, supporting orchid seed banking as a valuable part of emerging integrated conservation strategies.

PLANTS, PEOPLE, PLANET, EarlyView.Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

Factors Influencing Date Pollen Viability
Journal of Agricultural and Marine Sciences, 1997 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

Room-Temperature Storage of Coconut Pollen [PDF]
Nature, 1962 POLLEN introduction and exchange have been suggested as a means of broadening the scope of breeding programmes designed to produce disease-resistant and high-yielding coconuts1–3; and at a recent meeting of the Food and Agriculture Organization Technical Working Party on Coconut Production it was stressed4 that the most important material question to ...

Comparison of 5 Pollen Storage Protocols for Subtropical Pine Species
, 2005 Storage of pine pollen for breeding and conservation purposes is essential to conserve valuable genetic material over time. Customized storage protocols are often necessary to address differing strategies and program goals for specific pine species ...
