The level of damage to the cell membranes is a sign of aging of the seeds and a decrease in their viability. Conductometric seed testing method indirectly utilizes uncontrolled leakage of ions from seeds with damaged cell membranes to assess their viability. This involves the use of an electrical conductivity of the aqueous solution, in which seeds are soaked. The research was conducted in the years...

Black alder, a major forest tree species in Europe, thrives in moist soils. During the seeds extraction (nutlets) from the cones, the heaviest seeds were observed to fall out first. Seed weight was not correlated to the ability of germination; no significant differences were observed between the heaviest and the lightest seeds. Seeds with a fresh mass moisture content of 8−9% after storage in –3°C...
Cryopreservation in liquid nitrogen (–196°C, LN) is the method of long−term conservation of plant tissues, which has been evolving for many of seed of woody plant species. During cryopreservation protocol to LN in plant cells take place the supercooling tissue water or vitrification, which allows the successful storage. Water content was a significant determining factor with survival of cryostored...
