| 中文摘要 | Desiccation tolerance can be induced by culturing somatic embryos of loblolly pine (Pinus taeda L.) on medium supplemented with 50 muM abscisic acid (ABA) and/or 8.5% polyethylene glycol (PEG(6000)). Scanning electron microscopy of desiccated somatic embryos showed that the size and external morphology of the desiccation-tolerant somatic embryos recovered to the pre-desiccation state within 24-36 h, whereas the non-desiccation-tolerant somatic embryos did not recover and remained shriveled. after rehydration. Peroxidase activity of desiccated somatic embryos increased sharply after 1 d of desiccation treatment at 87% relative humidity (RH), and desiccation-tolerant somatic embryos had higher peroxidase activity compared to sensitive somatic embryos. Higher peroxidase activity of desiccation-tolerant somatic embryos map have allowed them to catalyze the reduction of H(2)O(2) produced by drought stress, and protected them from oxidative damage. |
