Cryobiology, 2020
Cryopreservation of pollen is a complementary conservation strategy and can be used for conserve the diversity in the genus Psidium. The present study aims to cryopreserve the pollen of Psidium species to overcome asynchronous flowering.

Sugarbeet Pollen Viability Indicators
Journal of Sugarbeet Research, 1989Ten 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, 2004Biological 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.

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

Membrane State and Pollen Viability
Annals of Botany, 1981The 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 ...

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.

Papaya pollen viability and storage
Scientia Horticulturae, 1989Abstract Papaya pollen viability, tube growth and storage were studied. Pollen germination on a drop of modified Brewbaker medium at 22–26°C closely reflected in vivo germination. Two vital stains gave pollen viability estimates that correlated closely with pollen germination percentage.

Hybrid Tea-rose pollen. II. Inheritance of pollen viability
Euphytica, 1977Pollen viability was evaluated in about 500 seedlings originating from 31 crosses between nine commercial Hybrid Tea-rose varieties. The data indicated that pollen viability was inherited additively.

Pollen production and pollen viability in male jojoba plants
Industrial Crops and Products, 2003Jojoba (Simmondsia chinensis (Link) Schneider) is a dioecious wind pollinated shrub native to the Sonora desert of the southwestern USA and Northern Mexico. A comprehensive program for the selection of female cultivars was conducted in Israel for many years. However, selection for male cultivars as pollen sources has largely been neglected. The current

Flower closure enhances pollen viability in Crocus discolor G. Reuss
Flora: Morphologie, Geobotanik, Oekophysiologie, 2019Repetitive flower closure (nyctinasty) is influenced by various regulatory mechanisms, but its ultimate function remains unclear. It is hypothesized that closed corolla may protect a plant's reproductive organs against various unfavourable environmental ...
