Abstract: Taking different transgenic cotton as test materials for pot experiment, the lignin content, POD and PAL activities in different cotton tissues were studied to reveal the change of lignin metabolism in transgenic cotton. The results showed that in comparison with non-transgenic cotton, the lignin content, POD and PAL activities in transgenic cotton change somewhat in some varieties, stages and tissues. At squaring stage, the lignin content lowers significantly by 34.96%, 27.15% and 13.22% in Z30 stems, CCRI41 stems and SGK321 leaves, respectively. However, no significant change is found in the total lignin content for all transgenic cotton in experiments.
