Cold hardening is a process in which a plant undergoes physiological changes to avoid, or mitigate cellular injuries caused by sub-zero temperatures. [1] Non-acclimatized individuals can survive −5 °C, while an acclimatized individual in the same species can survive −30 °C.
The ability to control intercellular ice formation during freezing is critical to the survival of freeze-tolerant plants. [3] If intracellular ice forms, it could be lethal to the plant when adhesion between cellular membranes and walls occur. The process of freezing tolerance through cold acclimation is a two-stage mechanism: [4]
When freezing temperatures threaten, we can take steps to insulate plants against the cold. For brief freezes, you can simply cover plants with blankets, towels, burlap, or other insulating materials.
Cold, drying easterly winds can also severely inhibit spring growth even without an actual frost, thus adequate shelter or the use of windbreaks is important. Drought can cause plants to suffer from water stress and wilt. Adequate irrigation is required during prolonged hot, dry periods. Rather than shallow daily watering, during a drought ...
In addition to cold tolerance, plant hardiness has been observed to be linked to how much stress specific plants are undergoing into the winter, or even how fast the onset of cold weather is in a specific year. This means that often stressed plants will exhibit less cold tolerance than plants that have been well maintained.
These plants would be much better off if the weather would stay cold until it was ready to turn warm in earnest. Each warm spell makes the next cold spell feel that much more frigid to me and ...
In botany, perennation is the ability of organisms, particularly plants, to survive from one germinating season to another, especially under unfavourable conditions such as drought or winter cold. It typically involves development of a perennating organ , which stores enough nutrients to sustain the organism during the unfavourable season, and ...
