Plants that are most susceptible to frost damage include tender annuals such as tomatoes, peppers, and basil. Delicate perennials, young seedlings, and tropical plants like hibiscus and citrus ...
Plants likely to be damaged even by a light frost include vines—such as beans, grapes, squashes, melons—along with nightshades such as tomatoes, eggplants, and peppers. Plants that may tolerate (or even benefit from) frosts include: [11] root vegetables (e.g. beets, carrots, parsnips, onions)
Non-acclimatized individuals can survive −5 °C, while an acclimatized individual in the same species can survive −30 °C. Plants that originated in the tropics, like tomato or maize, don't go through cold hardening and are unable to survive freezing temperatures. [3]
The loss of frost resistance occurs after warming. Rapid temperature fluctuations during winter deharden trees and increase the risk of spring damage. [5] Species that bloom first even before the leaves develop like apricots or peaches, are particularly vulnerable to damage. The reproductive organs, due to their abundant hydration, are easily ...
These numbers then get higher, with damage being more likely the further along the buds are. Full bloom on apples (their final bud stage) will have a 10% fruit loss at 28 degrees and a 90% fruit ...
Within the apoplast, antifreeze proteins localize the growth of ice crystals by ice nucleators in order to prevent physical damage to tissues and to promote supercooling within freezing-sensitive tissues and cells. Osmotic stress, including dehydration, high salinity, as well as treatment with abscisic acid, can also enhance freezing tolerance.
The magic of a perfectly ripe tomato is a fleeting moment in the heat of summer. Whether you’re a green-thumbed grower or you just frequent your farmers’ market on the weekend to stock up on ...
Tender plants are those killed by freezing temperatures, while hardy plants survive freezing—at least down to certain temperatures, depending on the plant. "Half-hardy" is a term used sometimes in horticulture to describe bedding plants which are sown in heat in winter or early spring, and planted outside after all danger of frost has passed.
