The analysis of the chemical constitutes among sterns roots and leaves of Dracaena cochinchinenis, showed that there' s small amount loureirin A in their extracts, with 0.053mg/g, 0.058mg/g, 0.015mg/g respectively only. Therefore, the roots, stems and leaves of Dracaena cochinchinenis have too low contents of loureirins to be raw materials of dragon's blood.
分析剑叶龙血树根、茎、叶的成分,发现风干的剑叶龙血树根、茎、叶中没有龙血素B的存在,只含有少量的龙血素A,其含量在根、茎、叶中分别为:0.058mg/g,0.053mg/g,0.015mg/g,其含量远低于现行的龙血竭中龙血素A含量不低于2%的质检标准,因此剑叶龙血树的根、茎、叶不能直接用作生产龙血竭的原料。

Only one case had length of styloid process less than 30mm and inclined angle less than 25 degree on both sides. Conclusion: Excessive length of styloid process and abnormal angle play important role in diagnosing styloid process. 64slice spiral CT three dimension VR and MPR can display styloid process clearly in three dimension space, measure the length exactly, and show the relationship between styloid process and tissue around distinctly. It is a precise and ideal way for diagnosis of styloid process.
茎突过长结合角度异常是诊断茎突综合征的重要依据。64排螺旋CT MPR和VR重建能清楚、直观地显示茎突在三维空间的全貌,准确地测量其长度、角度以及反应其与周围组织结构的关系,是诊断茎突综合征的一种较准确、且理想的检查方法。

The results showed that the rooting rate reached 83.2%~96.3% in 1/2 MS medium with IBA1.0~1.5 mg/L, The rooting rate of stem with top was significantly higher than that of stem without top; Snicking in stem base increased root number obviously, The appropriate substratum for transplanting was perlite and soil (1:1), The growth tendency of transplanting plantlets in May was slow-fast-slow.
结果表明:采用1/2MS培养基添加IBA1.0~1.5 mg/L,生根效果最好,平均生根率达83.2%~96.3%;带茎尖茎段的生根率显著高于不带茎尖茎段;茎段基部刻伤处理后较对照生根量明显增加;酸枣带根组培苗适宜的移栽基质为1:1的珍珠岩和土;5月份移栽下地的组培苗,其生长呈现慢-快-慢的趋势。

We measured morphological and physiological characteristics of C. asiatica in spring 2004 and 2005 at three levels: ramet population, clonal fragment and leaf. Environmental factors of different microsites were investigated again in September 2006. Important findings At the ramet population level, we observed no effect of habitat (forest edge vs. abandoned grassland slope).
