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.
Early Girl can tolerate temperatures as low as 40 °F (4 °C) [1] and is well-suited to hot, dry climates. [2] Early girl is reliable and prolific. The ripe fruit is extremely standard for a tomato, about the size and shape of a tennis ball and weighing 4 to 8 ounces (110 to 230 g). The tomatoes have a bright color and good flavor.
The process of freezing tolerance through cold acclimation is a two-stage mechanism: [4] The first stage occurs at relatively high subzero temperatures as the water present in plant tissues freezes outside the cell. The second stage occurs at lower temperatures as intercellular ice continues to form.
Eggplants tolerate zero cold, so plant after all danger of frost has passed. They love the heat and grow best when temperatures are between 70 to 85 degrees. You’ll find varieties that are dark ...
It has been adapted by and to other countries (such as Canada) in various forms. A plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 to 40 °F (−1.1 to 4.4 °C). Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale.
Also called ice pansies, winter pansies come in blues, purples, reds, pinks, and beyond.
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 plant starts the adaptation by exposure to cold yet still not freezing temperatures. The process can be divided into three steps.
A gene from rice (Osmyb4), which codes for a transcription factor, that was shown to increase cold and drought tolerance in transgenic Arabidopsis thaliana plants, was inserted into the tomato. This resulted in increased drought tolerance, but did not appear to have any effect on cold tolerance. [19]
