Freezing suitability of petunia
Petunia Juss.
The concept of petunia freezing suitability does not exist due to the crop's lack of culinary value. In agronomy, the term is viewed solely as the destructive effect of sub-zero temperatures on plant tissues.
In the reference 29 varieties crop Petunia, where this is mentioned in the description.
Petunia is a thermophilic crop of tropical origin that lacks genetic hardening mechanisms, such as tissue dehydration or the synthesis of antifreeze proteins. At temperatures of 0°C and below, ice crystals form within the tissues, destroying cell membranes, which leads to the irreversible death of all vegetative organs.
Scientific research in the field of petunia cold tolerance is aimed exclusively at increasing plant survival in unheated greenhouses during the growing season. No work is being done to create varieties suitable for industrial or domestic freezing, as exposure to cold is a critical damaging factor for this crop.
