Effects of Boron on Pollen Viability in Wheat
Plant and Soil, 1993Grain set failure in wheat, caused by boron (B) deficiency, is associated with poorly developed pollen and anthers. This paper presents results of a study of the effect of B on pollen viability when it was supplied “internally” through the roots and externally in an agar medium for in vitro germination.

A SIMPLE POLLEN VIABILITY TEST
Australian Forestry, 1958SUMMARY A simple method of determining the germination of pine pollen is described. It consists of Ousting the pollen to be tested on a slide which is placed over water in a petri dish, which is kept at about 25°C for 72 hr. The use of cotton blue stain applied 'at the time of examination assists counting the germinated grains, especially when they are

Air quality biomonitoring through pollen viability of Fabaceae
Environmental Monitoring and Assessment, 2012In this study, pollen viability and germination of three plant species, Cercis siliquastrum L., Robinia pseudoacacia L., and Spartium junceum L., belonging to the Fabaceae family, was evaluated in sites with different intensity of road traffic, constantly monitored with continuous analysers for air pollutants (carbon monoxide (CO), sulphur dioxide (SO ...

POLLEN VIABILITY AND GERMINATION RATES OF 45 WATERMELON GENOTYPES
Acta Horticulturae, 2007This study was conducted at the Department of Horticulture, Faculty of Agricultureof Cukurova University in 2002. Eighty three watermelon accessions,collected from different regions and provided by the Turkish genebank (MenemenAgricultural Research Institute), were used for this study. Watermelon plants weregrown in the research greenhouses of Cukurova

Pollen Tube Growth in vivo as a Measure of Pollen Viability
Science, 1962Observation by fluorescence of tomato pollen tubes in fixed styles clearly showed that all pollen samples grew regardless of age and fruit or seed setting potential. Methods commonly used to evaluate pollen viability, such as staining and germination, may predict growth in the style but do not always predict seed setting ability.

Viability of Cururbita pepo pollen: biophysical and structural data
Planta, 1989During ageing of the short-lived pollen grains of Cucurbita pepo L., water loss was examined in relation to viability using biophysical ((1)H-nuclear magnetic resonance, NMR) and cytological methods (fluorochromatic reaction test, freezefracture and scanning electron microscopy).

STUDIES ON POLLEN VIABILITY AND POLLEN-STIGMA COMPATIBILITY OF HYBRID HAZELNUTS
Acta Horticulturae, 2014The studies are to select pollinated cultivars of hybrid hazelnut (Corylus heterophylla Fisch. A C. avellana L.) by testing the pollen viability and pollen-stigma compatibility. The pollen viability of 5 hybrid hazelnuts was tested with the agar culture method.

Storage and Viability Assessment of Date Palm Pollen
2017Pollen storage and viability are very important for pollination, breeding, biodiversity, biotechnology, conservation, and other biological and non-biological studies of the date palm. Optimizing procedures and duration of storage are important for effective and long-term date palm pollen storage and viability.

[Effect of cryopreservation on pollen viability].
Bollettino della Societa italiana di biologia sperimentale, 1991The viability of pollen at room temperature lowers and disappears in few days; on the contrary the cryopreservation lengthens the pollen viability. Pollen of Pinus brutia, P. canariensis, P. halepensis, P. pinaster has been stored at -20 degrees C for one year with the aim of checking the variation of viability.
