Description: Deep-freezing of pine pollen offers a means of prolonging its storage life. Early work showed that pollen could be frozen without losing its viability. A study was started in 1958 at the Institute of Forest Genetics at Placerville to determine how long frozen pollen of several pines would remain viable. This paper reports in vitro germination and in vivo seed production by pollens stored at -20ºC. up to 5 years.
