摘要：

Order parameters of chloroplast membrane lipids of rye wheat seedlings differing in cold hardiness were compared before after hardening. Seedlings grown at 25° exhibited similar membrane microviscosities. When hardened, the cultivars most resistant to freezing temperatures possessed the most fluid membranes, while those sensitive to cold were unable to alter them. Changes in linolenic acid levels alone cannot be responsible for the observed phenomena. © 1979.
