While this cryopreservation conservation strategy can be used on all plants, it is often only used under certain circumstances: 1) crops with recalcitrant seeds e.g. avocado, [2] coconut [3] 2) seedless crops such as cultivated banana and plantains [4] or 3) crops that are clonally propagated such as cassava, potato, garlic and sweet potato.

When chilled by dry ice, liquid carbon dioxide or liquid nitrogen, the thermoplastics can be finely ground to powders suitable for electrostatic spraying and other powder processes. [1] Cryogenic grinding of plant and animal tissue is a technique used by microbiologists .
A tank of liquid nitrogen, used to supply a cryogenic freezer (for storing laboratory samples at a temperature of about −150 °C or −238 °F) Controlled-rate and slow freezing, also known as slow programmable freezing (SPF), [18] is a technique where cells are cooled to around -196 °C over the course of several hours.
When you see the potatoes flowering, that means there are new, tender potatoes that can be dug up. You can harvest a few from each plant, then re-cover the plants with soil to let the rest of the ...
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]
4 interferes with Ca 2+ uptake and can be toxic to plants if used as a major nitrogen source. A 3:1 ratio of NO − 3-N to NH + 4-N (wt%) is sometimes recommended to balance pH during nitrogen absorption. [71] Plants respond differently depending on the form of nitrogen, e.g., ammonium has a positive charge, and thus, the plant expels one ...
