Viability and storage of bromeliad pollen
Euphytica, 2002Several 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 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.

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

Germination and viability of the pollen of Crocus sativus L
Giornale botanico italiano, 1982Abstract 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.

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.

The viability and storage of strawberry pollen
Plant Breeding, 1995AbstractInvestigations 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 ...

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.

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

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).
