To counter the technical difficulty arising in separation of slag and antimony during low temperature smelting of antimony concentrate, a rational technical scheme has been proposed and proved theoretically through practice.

The effects of cold acclimation on leaf physiological traits in rice seedlings;

Protein expression of two Spiraea species under effects of cold acclimation and de-acclimation

Whether or not cucumber seedling accepted cold acclimation had intimate connection with chilling tolerance of cucumber seedling before cold acclimation.

Increment of Chilling Tolerance and Its Physiological Basis in Chilling-sensitive Corn Sprouts and Tomato Seedlings after Cold-hardening at Optimum Temperatures;

Seedling freezing tolerance increased after 15 d of cold-hardening.

Low temperature signal in woody plants,Populus davidiensis cuttings after being treated with CaCl_2,Ca~(2+) chelator EGTA,Ca~(2+) channel inhibitor LaCl_3 or CaM antagonist CPZ were used for freezing acclimation.

49) in the enhancement of freezing resistance induced by freezing acclimation, G6PDH was purified from the leaves of 8-week-old Populus suaveolens cuttings.

To explore the role of calcium-calmodulinmessenger system in the transduction of low tempera-ture signal in woody plants, Populus tomentosa cut-tings after being treated with CaCl2 (10 mmol/L), Ca2+chelator EGTA (3 mmol/L), Ca2+ channel inhibitorLaCl3 (100 mmol/L) or CaM antagonist CPZ (50 mmol/L) were used for freezing acclimation at -3℃.
