Pollen viability and pollen vigor

Theoretical and Applied Genetics, 1991
Investigations were carried out to correlate pollen viability, assessed on the basis of a fluorochromatic reaction (FCR) test, with pollen vigor, assessed on the basis of the time taken for in vitro germination in pollen grains subjected to high humidity (>95% RH) and temperature (38 °C) or storage stress of Nicotiana tabacum, Agave sp., Tradescantia ...

Sugarbeet Pollen Viability Indicators

Journal of Sugarbeet Research, 1989
Ten fluorochromes and seven stains were evaluated as indicators of viability of sugarbeet (Beta vulgaris) pollen. The reactions of these materials were com­ pared with in vitro germination of pollen in a liquid medium. Among these 17 materials, fluorescein diacetate (FDA), 3-(4,S-Dimethylthiazol-2-yl)-2,S­ diphenyl-2H-tetrazolium bromide (MTT), and ...

Pollen Viability for Air Pollution Bio-Monitoring

Journal of Atmospheric Chemistry, 2004
Biological characterization of Corylus avellana L. and Pinus nigra L. pollen samples was carried out to determine the actual value of pollen as a bio-indicator of the effects of atmospheric pollution, using samples from plants naturally developed in sites controlled for air pollution.

Pollen viability testing.

2018
Abstract Pollen viability is essential for success in pollination. Fresh pollen shed from flowering male inflorescences has the highest viability, and it is this which is harvested and stored (Ekaratne and Senathirajah, 1983). Viability tests are carried out prior to processing pollen to ensure the harvested pollen has high viability, and again

A method to estimate pollen viability from pollen size variation

American Journal of Botany, 2002
The mean diameter of viable pollen grains is approximately 13 μm greater than the mean diameter of inviable grains in Mimulus guttatus. We show that this difference is large enough to be detected by particle counters and that these machines can be used to obtain a rapid estimate of pollen viability.

Membrane State and Pollen Viability

Annals of Botany, 1981
The relationship between germinability and fluorochromasia (FCR) has been studied in pollen of eight genera, Secale, Iris, Carex, Eleocharis, Cytisus, Digitalis, Plantago and Lonicera. The FCR tests two properties of the pollen, (a) the integrity of the plasmalemma of the vegetative cell and (b) the presence of an esterase capable of cleaving the ...

Tests for Pollen Viability

1992
Viability means ability to live; but pollen viability connotes the ability of pollen to complete post-pollination events and to effect fertilization. In the old literature the terms pollen viability and pollen sterility were often used interchangeably.
