Taipei 309, to 4 °C leads to conditions of oxidative stress. Tissue H2O2 was observed to increase more than fourfold by 8 d of chilling, and levels of reduced glutathione, which normally rise in growing shoot cultures at 25 °C, were considerably repressed in chilled cultures. Whilst the activity of ascorbate peroxidase in chilled shoots remained similar to the activities in control cultures at 25 °C, the most notable effects of chilling to 4 °C were the very significant loss of catalase and glutathione reductase activity. Although prior exposure of shoot cultures to abscisic acid (ABA) at 25 °C increased levels of catalase activity, such increased levels were not sustained when the pre-treated cultures were placed at 4 °C. Moreover such pre-treatment with ABA did not increase the subsequent ability of shoot cultures to grow at 4 °C.
