The objective of the study was to follow morphological, selected biochemical and transcriptional characteristics induced by various air humidity during desiccation of Norway spruce somatic embryos. The level of free polyamines lowered, higher forms of polyamines were favoured. Expression profiles of monitored genes were variously influenced by different relative air humidity. Our data proved, that desiccation of somatic embryos is metabolically active process highly affected by relative air humidity.

Somatic embryogenesis is a developmental process where a plant somatic cell dedifferentiate to a totipotent embryonic stem cell that has the ability to give rise to an embryo under appropriate conditions. Desiccation is the final phase of normal embryonic development in most angiosperms and appears to be important in the transition from embryogeny to the ability to germinate and form normal seedlings.
