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.

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 Tube Growth in vivo as a Measure of Pollen Viability

Science, 1962
Observation 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.

Papaya pollen viability and storage

Scientia Horticulturae, 1989
Abstract 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.

Viability and storage of bromeliad pollen

Euphytica, 2002
Several bromeliad species from two different subfamilies, were used to develop a reliable method to evaluate pollen viability. Pollen germination on a medium containing 20% sucrose, 0.001%H3BO3 and 0.5% agar was comparable to germination on a compatible stigma. Maximum germination was reached within 2 to 10 hours depending on the species. Based on this

Pollen production and pollen viability in male jojoba plants

Industrial Crops and Products, 2003
Jojoba (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

The viability and storage of strawberry pollen

Plant Breeding, 1995
AbstractInvestigations were carried out in 1990 and 1991 to estimate the pollen viability of five strawberry genotypes and their suitability for storage. Pollen viability was assessed by acetocarmine staining, in vitro germination, and in vivo assays. Pollen was stored in darkness at −18°C for 1 year, and pollen viability was estimated every 4 months ...

Germination and viability of the pollen of Crocus sativus L

Giornale botanico italiano, 1982
Abstract Viability and germinability tests were carried out on the pollen of Crocus sativus L., a sterile triploid commonly known as saffron. Pollen taken from dehiscent anthers was examined by means of vital staining and cytochemical techniques in order to detect its viability; germination in vitro was evaluated.

Hybrid Tea-rose pollen. II. Inheritance of pollen viability

Euphytica, 1977
Pollen 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.
