Either sodium picrate, which is converted to sodium isopurpurate, or a freshly prepared solution of guaiacum resin in absolute alcohol which is allowed to dry on the paper and treated with very dilute copper sulphate solution. The latter test-paper turns blue with prussic

acid。苦味酸钠试验：将生药研碎，取0.5g放入试管中，加数滴水润湿，加塞密闭，管口内悬挂一条用碳酸钠溶液润湿的苦味酸试纸，将试管置40～50℃水浴进行酶解，试纸转为砖红色，若是悬挂联苯胺-硫酸铜试纸，则应生成联苯胺氧化物而使试纸变蓝色。

Results showed: under the condition of liquid culture, 29℃/20℃ and 8 hours light time per day, the induction rate and the fresh weight of microcorm reached the highest. If the fresh weight of microcorm is more than 0.8g, the mean sprouting rate of the 4 genotypes was more than 80％.

试验结果表明：在以液体培养方式、温度为29℃(1ight)／20℃和光照时间为8h／d时的条件下，试管球茎的诱导效率达到95％以上，单瓶试管球茎的最大鲜重和平均鲜重也达到4.5g和2.0g以上。

an approach divides the sonoluminescence from the sound field by using test tube with black plastics and the isotropic light trap is applied to collect sonoluminescence in the trough which irradiates hematoporphyrin out of the sound field.the results of our work suggest that ultrasonically induced cavitation produces nonequilibrium high temperature, emits shock waves, together with the cavitation energy in hematoporphyrin solution activating hematoporphyrin.

从超声空化产生的声致荧光出发，采用试管外包裹黑色塑料的方法将大量生理盐水的声致发光与其余能量形式分开，在相同条件下，使用集光球收集水槽中盐水的声致荧光，将荧光引出声场单独作用血卟啉。结果表明，水槽中盐水的空化热能、冲击波与试管中血卟啉溶液空化产生的高温、高压、冲击波等多种能量的合作用激活血卟啉。

When the Gerbera test-tube plantlets are transplanted, the best medium is 3 turf: 2 vermiculite: 1 margarite for against bacteria and can get more plant from plantlets.

生根试管苗的移栽以草炭3：蛭石2：珍珠岩1为好，移栽时一定注意使用多菌灵防止杂菌的滋生，以提高非洲菊试管苗的成活率。

It turned out reproduction rete of chrysanthemum was raised,the regular,non-plant diseases and insect pests could be offered to the market. Shoot tip were used as explants to study the effects of different sterilization methods, illumination intensity and concentrations of 6-BA and NAA on shoot propagation. Rooting with perlite, vermiculite and river sand instead of agar was studied. In the process of preliminary multiplication, the effect of using 0.1% HgCl_2 in sterilization of explants was better than using saturated bleaching solution. The highest multiplication rate was found under whole illumination. MS media with 6-BA from 0.2 mg·L~(-1) to 5 mg·L~(-1) and NAA from 0.05 mg·L~(-1) to 2 mg·L~(-1) were tested and as a result, the highest differentiation rate and the multiplication rate was reached with 0.2 mg·L~(-1) 6-BA, 0.05 mg·L~(-1) NAA.

本实验以菊花的茎尖为外植体，研究了不同灭菌方法，光照强度，全光照、半光照和弱光处理以及不同6-BA和NAA浓度及配比对于试管苗增殖的影响，并研究了珍珠岩、蛭石和河砂等琼脂替代物对于菊花生根的影响，结果表明：在初代培养物建立的过程中采用0.1％升汞进行表面灭菌的效果好于饱和漂白粉的灭菌效果；在全光照条件下外植体的增殖倍数最高；在试管苗增殖培养的过程中，以MS为基本培养基，并在培养基中添加0.2～5mg·L~(-1)6-BA和0.05～2mg·L~(-1)NAA，其中0.2mg·L~(-1)6-BA和0.05mg·L~(-1)NAA最适于外植体的分化和增殖，其分化率为100％，增殖倍数为12。

After cultivated, tube plantlets weren't evidently different compared with the control (inoculated under no NaClO, free virus conditions) in main growth indexes,which showed that Oncidium' s tube plantlets could be inoculated under open conditions when film culture vessels were used.
