[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.

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.

A SIMPLE POLLEN VIABILITY TEST

Australian Forestry, 1958
SUMMARY 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

POLLEN VIABILITY AND GERMINATION RATES OF 45 WATERMELON GENOTYPES

Acta Horticulturae, 2007
This study was conducted at the Department of Horticulture, Faculty of Agricultureof Cukurova University in 2002. Eighty three watermelon accessions,collected from different regions and provided by the Turkish genebank (MenemenAgricultural Research Institute), were used for this study. Watermelon plants weregrown in the research greenhouses of Cukurova

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).

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.
