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.

Viability of Cururbita pepo pollen: biophysical and structural data

Planta, 1989
During 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, 2014
The 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

2017
Pollen 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, 1991
The 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.

POLLEN VIABILITY AND POLLEN TUBE ATTRITION IN CRANBERRY (VACCINIUM MACROCARPON AITON)

Acta Horticulturae, 2009
The content of mature seed in a cranberry fruit increases with stigmatic pollen load. On average, however, only two seeds result for every tetrad of pollen deposited. What then is the fate of the two remaining pollen grains fused in each tetrad? Germination in vitro revealed that most of the grains in every tetrad were viable and could initiate a ...
