Figure 3From: Cold tolerance in Osmotin transgenic tomato (Solanum lycopersicum L.) is associated with modulation in transcript abundance of stress responsive genes Effect of cold exposure on ascorbate content in transgenic and wild type tomato plants exposed to cold treatment. Plants at 90 days after transplanting were exposed to cold treatment for 2 and 24 h and ascorbate content was analyzed in leaves. The values are mean (n = 4) fold ascorbate content over the respective untreated control. Error bars indicate SE. The mean values in one series indicated by different letters are statistically significant (P ≤ 0.05) according to LSD test.Back to article page
