Abstract: With the sliding section, histochemical staining, paraffin section, scanning electricity microscope and spectrophotometry, we studied the anatomical structure and histochemcial characteristics of barrier zone. The barrier zone was arisen from interxylary phloem. Barrier zone in different thickness located between agarwood zone and transition zone. The barrier zone was formed of abnormal parenchyma and xylem. Barrier zone contained a small amount of starch and more total sugar. Our results might be used to eliminate and delay the barrier zone, and improve whole-tree agarwood-inducing technique.

Key words: Aquilaria sinensis, interxylary phloem, barrier zone, whole-tree agarwood-inducing technique
