  ginseng
The contents of macroelements and microelements in ginseng roots and callus cultures was determined by atom absorption spectroscopy.
      
Ginseng cells and tissues were shown to accumulate considerable amounts of microelements.
      
The content of six of the eleven mineral components studied (K, Ca, Na, Mo, Mn, and Cr) in callus cultures was higher than that in roots of agricultural ginseng plants.
      
We revealed good correlations between the contents of microelements (K, Ca, and Mg), as well as between the concentrations of macroelements (Mo, Li, Cu, and Cr), in ginseng cultures.
      
The ability to accumulate elements varied between ginseng species, which was probably related to their genetic features.

Mixed-function oxidases (MFO) , which degrate or activate foreign compounds in organisms, play an important role in the lexicological impact of the environment, human-body, animal and drug. This paper reports that the level of microsomal epoxidation in the mid-gut tissues of sixth instar southern armyworm larvae was persistently enhanced following oral in vivo administration of Panax Ginseng or Pseudoginseng. Owing to increased activity of microsomal epoxidasc, the duration of the sixth instar larvae and the pupae was Shortened as compared with the control, and the resistance to carbaryl increased to more3.9 times than the control.The resistance to insecticide in the post-stage of the last instar was higher than that in the pre-stage in which the microsomal aldrin epoxidase activity was weaker.Synergists ( MDP, PB or RO- 5 -8019 ) enhanced the toxicity of a variety of insecticide inhibiting microsomal enzymes, but RO-5-8019 caused larvae to die and the formation of abnormal pupae.Alcohol and methanol extracts of the seed kernals of Melia toosendan showed similar action as RO-5-80I9 to the armyworm larvae.

微粒体的多功能氧化酶(Mixed-Function Oxidases)(MFO),由于它在生物体内对外来物质具有降解或活化的特殊功能,是当前环境人体、动物及药物毒理上占有重要地位。本文首次报告含有三萜烯化合物植物质(人参和三七)对秋粘虫(Spodoptera eridania)幼虫“MFO”有较持久性诱导活性、促使幼虫和蛹历期缩短并提高对西维因(Sevin)的抗药力达3.9倍。同时研究该虫第六龄幼虫中肠“MFO”酶活性的消长变化与抗药性的相关性,发现幼虫前期酶活性低于中后期,抗药力与酶活性呈正相关。如用二氢黄樟脑(MDP)增效剂抑制该酶后可以增加西维因毒力达一倍。具有“丙炔”结构的增效剂(RO—5—8019)不仅有抑制“MFO”对药物增效,而它本身也对昆虫产生迟效性毒性(部分幼虫发育阻滞死亡及蛹化畸形),川楝甲醇或乙醇抽提物也同样与丙块增效剂对秋粘虫或粘虫(Mythimna separata)幼虫有相似作用,可能与川楝种核粉中含有某些增效物质有关,是一类有前途的特异性杀虫药剂。

Studies on root rot caused by Cylindrocarpon destructans (Zinss)Scholten in ginseng revealed that latent infection from this fungus wasfound in healthy ginseng root.In the 1-5-year-old roots,root rot per-centage and latent infection sites increased with the age.The root sys-tem of 3-year-old seedling could be all infected,especially the tap root. In pot trials,deer feces amendment significantly reduced both theroot rot percentage and the disease index of ginseng roots to 50% morethan those...

Studies on root rot caused by Cylindrocarpon destructans (Zinss)Scholten in ginseng revealed that latent infection from this fungus wasfound in healthy ginseng root.In the 1-5-year-old roots,root rot per-centage and latent infection sites increased with the age.The root sys-tem of 3-year-old seedling could be all infected,especially the tap root. In pot trials,deer feces amendment significantly reduced both theroot rot percentage and the disease index of ginseng roots to 50% morethan those of the chock.Transplanting 3-year ginseng seedling in sp-ring,good results would be obtained in the control of root rot.

试验表明,人参锈腐病菌[Cylindrocarpon destructans(Zinss)Schol-ten]具有潜伏侵染的特性。在1—5年生外观无病斑的参根内,是普遍带有潜伏的锈腐病菌,参根的带菌率和潜伏侵染点值,随根龄的增长而增高。3年生人参的根系中,主根对锈腐病菌的感染率最高。春季移栽3年生参根、盆栽鹿粪和50%禾穗胺600倍侵根,均对该病菌有一定的防治效果。

The black-fleck disease of ginseng may reduce ,the yeild of the plant's roots by 40~160%; in severe cases, as much as ten times or even more. The name of black-fleck disease of ginseng (Alternaria panax whetz) was originally given to a disease that attacks American ginseng. However, the conidia of this fungus in Liaoning Province are appreciably larger than the American isolates. We inoculated 29 weed species with this fungus but could find no other host on the experimental farm. The starting...

The black-fleck disease of ginseng may reduce ,the yeild of the plant's roots by 40~160%; in severe cases, as much as ten times or even more. The name of black-fleck disease of ginseng (Alternaria panax whetz) was originally given to a disease that attacks American ginseng. However, the conidia of this fungus in Liaoning Province are appreciably larger than the American isolates. We inoculated 29 weed species with this fungus but could find no other host on the experimental farm. The starting temperature for the germination of the conidia was 1℃; the optimum temperature was 20°~25℃. The highest germination rate of conidium was found in ginseng leaf sap 1% sugar solution and dew under saturated humidity, the lowest, in distilled water. Solution of soil extract showed strong inhibition to the germination of conidia. The conidia were the cause of infection, Germinating spores invade the plant through epidermis, with an in incubation period of 24~48 hours. Conidia are produced 3~6 days after inoculation, and this process can repeat in the same infected region. In one square centimeter of leaf there can be as many as 4, 107~51, 120 spores. Overwintering diseased leaves can also produce conidia and cause iufection. The conidium has no dormant peroad, it can not injure woody stems. The black-fleck disease is an epidemic disease, which is restricted to small areas. The conidium is large in size, with limited bouyancy, Which hampers its transmission by air. The amount of pathogens present in the field is positively correlated with the incidence of the disease, The climatic conditions in Liaoning Province makes this region an area of frequent occurrence of the disease.

人参黑斑病可使参根减产0.4~1.6倍;重者达10倍以上。人参黑斑病菌Alternaria panax whetz.原取名西洋参;经测定辽宁的分主孢子尺度明显偏大。接种和调查29种杂草,在参场内未见其它奇主.分生孢子萌发的起点温度为1℃±;最适为20~25℃。孢子以在人参叶汁、1%糖水、露水和饱和湿度下萌芽率最高:在蒸馏水、自来水中萌芽率最低;土壤对孢子萌发有强烈抑制作用。病害的侵染来源是分生孢子,以穿透方式侵入,潜育期24~48小时,接种3~6天产生孢子,且病部可反复多次产生,每平方厘米病叶可产孢4,107~51,120个;越冬病叶也可再次产生孢子和造成侵染。孢子没有休眠期,随时可以萌发侵染,但不能为害木质化的茎秆。黑斑病具有小区内局部流行特点。孢子体形大,浮动传播较差,田间菌源的多少与发病成正相关。据辽宁的气象条件,人参产区是黑斑病的长发区。
