Euphytica, 1986
To develop the technology for long-term pollen preservation, sugarbeet pollen was collected from plants grown in the greenhouse and in the field, and was stored 1 day to 1 year at 5, -18, and -196°C. Pollen containing about 12% moisture was successfully stored in liquid nitrogen (LN2) up to 1 year; this pollen effected fertilization of male-sterile ...

THE RELATIONSHIP OF STORAGE AND VIABILITY OF LILY POLLEN
Acta Horticulturae, 2003The study was conducted to estimate the pollen viability of eight lily genotypes and optimum storage conditions. Pollen viability was assessed by in vitro germination, FCR (Fluorochromatic raction) test and fruit set test. Pollen grains were stored in the dark chamber where the temperature was maintained at 4 °C, -20 °C, and ?70 °C and ambient room ...

Pollen collection and storage.
2018Abstract Shed pollen of oil palm is binucleate, it has two cells (one vegetative and one generative), and can live for about a week in situ. However, fresh pollen can be collected from flowering male inflorescences, purified and stored for over 20 years in cold, desiccated and vacuumed conditions. The processes involved are described.

Short-term storage of cotton pollen
Plant Cell Reports, 1986Several methods of storing cotton pollen (Gossypium hirsutum L.) were evaluated. A successful pollen storage method that maintains fertility would enhance the crossing of breeding materials. Storing pollen at ultra-low temperatures in liquid nitrogen or at 5°C was not successful. No storage method maintained pollen fertility for more than 72 h.

Pollen storage of Fragaria and Potentilla
Euphytica, 1989Low temperature and humidity were used for the storage of pollen of four species of Fragaria (2n=14, 42 and 56) and two species of Potentilla (2n=14). The stainability of Fragaria pollen was assessed over a number of years by use of aceto-carmine stain and its viability by cross-pollinations; stainability of Potentilla pollen was assessed by ...

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.

American Potato Journal, 1958
The pollen of four varieties of potatoes has been stored successfully at −20° C. (−4° F.) for eleven months. The viability of this stored pollen was tested by using it to make crosses. The stored pollen produced when used in hybridizations, as many seeds per berry as fresh pollen.

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

Vitality and storage condition ofSyringa pollen
Journal of Forestry Research, 2003The fresh pollen vitality, the effect of different storage conditions on the pollen vitality, and the difference of vitality among the species of seven species ofSyringa were determined in Shenyang, China. The results indicated that the pollen vitality (81.5%) ofSyringa villosa was the highest among the seven tested species, followed byS.
