Storage of sugarbeet pollen

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 ...

Short-term storage of cotton pollen

Plant Cell Reports, 1986
Several 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.

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.

Pollen collection and storage.

2018
Abstract 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.

Storage of avocado pollen

Euphytica, 1981
Avocado pollen was stored at a range of temperatures and relative humidities (RH) for up to one year and the pollen was tested for viability in vivo.
