Název v původním jazyce

Cryopreservation of hop pollen for hop breeding

Popis výsledku v původním jazyce

This work was focused on the evaluation of the thermal characteristics of pollen with respect to its hydration in samples of hops. The water content and the following characteristics related to the behaviour of water in the biological material under ultra-low temperatures were determined: the proportion of frozen water content, melting point and glass transition temperatures. We found that the resulting thermal properties were influenced mostly by water content and, conversely, the effect of variety and plant species was not significant; the dependence of the studied parameters was a function of the water content regardless of the tested genotype. When the water content falls below 0.27 g of water per gram of dry matter, water does not crystallize and at the same time, the presence of a glass transition has always been demonstrated.
