摘要: 分别采用滑走切片、组织化学染色、石蜡切片技术、扫描电镜技术和分光光度法等,对白木香通体结香过程中阻隔层的形成过程、解剖结构等特性进行了研究。结果显示:木间韧皮部内的薄壁细胞在伤害刺激下脱分化、分裂产生阻隔层;阻隔层位于沉香层和过渡层之间,其厚度变化较大,由薄壁细胞群和阻隔层木质部组成;阻隔层中含有少量的淀粉和较多的可溶性总糖。上述研究结果为消除或延迟阻隔层的产生提供参考,为进一步优化通体结香技术提供帮助。

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
