These, in turn, affect transcription, translation, intermediate metabolism, and photosynthesis, leading to an energy imbalance. This energy imbalance is thought to be one of the ways the plant detects low temperature. Experiments on arabidopsis show that the plant detects the change in temperature, rather than the absolute temperature. [2]
Chemical treatment on dormant plants has been proven to be an effective method to break dormancy, particularly in woody plants such as grapes, berries, apples, peaches, and kiwis. Specifically, hydrogen cyanamide stimulates cell division and growth in dormant plants, causing buds to break when the plant is on the edge of breaking dormancy.
Perennial and biennial herbaceous plants lose their frost-sensitive, above-ground parts before the winter, and regrow in the spring. Herbaceous plants that are annual, producing seeds before the winter, can also be considered to have winter rest in some form, because their seeds may stay inactive over the winter before germinating. Annual ...

Cryobiology of plants explores the cellular and molecular adaptations plants develop to survive subzero temperatures, such as antifreeze proteins (AFP) and changes in membrane composition. Cryopreservation is a critical technique in plant cryobiology, used for the long-term storage of genetic material and the preservation of endangered species ...
The following is a breakdown of the energetics of the photosynthesis process from Photosynthesis by Hall and Rao: [6]. Starting with the solar spectrum falling on a leaf, 47% lost due to photons outside the 400–700 nm active range (chlorophyll uses photons between 400 and 700 nm, extracting the energy of one 700 nm photon from each one)
An early light frost can wipe out your garden harvest for the season. When a light frost is expected, water your garden to wet the plants. So, a light water layer on your plants will help protect ...
