Freezing injury

Freezing injury, which is an important abiotic stress in horticultural crops, influences the growth and development and the production area of kiwifruit (Actinidia Lind1). Among Actinidia species, Actinidia arguta has excellent cold resistance, but knowledge relevant to molecular mechanisms is still limited.

Glycerolipids are the principal constituent of cellular membranes; remodelling of glycerolipids plays important roles in temperature adaptation in plants. Temperate plants can endure freezing stress, but even chilling at above-zero temperatures can induce death in tropical species.

It was found that 0.1 mM SA had a greater alleviating effect, decreasing the freezing injury in both varieties for at least 10 days after the application. Moreover, 0.1 mM SA had a greater effect on alleviation in Tokak by increasing the ice nucleation activity of apoplastic proteins extracted from the leaves.

Frostbite with vesiculation, surrounded by edema and erythema.The two most common nonfreezing peripheral cold injuries are chilblain (pernio) and immersion (trench) foot. Chilblain results from neuronal and endothelial damage induced by repetitive exposure to dry cold. Young females, particularly those with a history of Raynaud's phenomenon, are at greatest risk. Persistent vasospasticity and vasculitis can cause erythema, mild edema, and pruritus. Eventually plaques, blue nodules, and ulcerations develop. These lesions typically involve the dorsa of the hands and feet.
