Such plants usually have one or more domatia, cavities in stems, leaves or roods that house ants. These may be elaborate systems of cavities with many chambers, e.g. Myrmecodia, or simple hollows in internodes, leaf veins, petioles or stipular spines, e.g. whistling thorns.

这类植物通常都具有一个或多个虫菌穴，虫菌穴是在植株的根、茎、叶上用来容纳蚂蚁的空腔，这些空腔具有许多发达的小室，例如茜草科具有简单而中空的结间部，阿拉比卡咖啡具有含有空腔的叶脉，有的植物叶柄及托叶处也有这样的结构，例如牛角刺槐。

The mycelial growth of Rhizoctonia solani was promoted by vanillic acid and syringic acid at levels of 0.1~1 mM/L, and it was inhibited remarkably by p-counaric acid of over 1mM/L and modestly by ferulic acid. The radial extent of mycelia of Fusarium solani was increased significantly by ferulic acid of 0.1~1 mM/L and limitedly by p-coumaric acid. vanillic acid had paradoxcial effects on the growth, positively at low levels and negtively at high levels, on which Syringic acid had a slight effect.

试验结果显示：浓度为0.1~1mM/L的丁香酸对西洋参立枯丝核菌菌丝生长具有促进作用，香草酸也有一定的促进作用，但不呈浓度效应，浓度在1mM/L以上的香豆酸对其有显著的抑制作用，阿魏酸也有一定抑制作用；对于西洋参根腐菌，阿魏酸对其生长有明显促进作用，香豆酸也有一定促进作用，香草酸表现为低浓度促进，高浓度抑制作用，0.1~1mM/L丁香酸对其生长基本无影响。

The fungus CFCC84965,which was isolated from Meloidogyne hapla eggs in sweet melon roots grown in plastic house in Muping,Shandong province in 2002,was identified as Pochonia suchlasporia var.catenata and it is reported in China for the first time.

The experiment lasted 6 weeks and the chicklings ingested feed and drank water freely. Group 1 was control group and groups 2, 3 and 4 were experiment groups, which were fed on the basic diet with additives of 220 mg/kg APS, 4×10^7 cfu/g PM and 220 mg/kg APS + 4×10^7 cfu/g PM.

试鸡按体重随机分为4个组，1组为对照组，饲喂玉米－豆粕型基础饲粮；2~4组为试验组，饲粮是在基础日根基础上分别添加黄茂多糖(220mg/kg)、益生菌剂(4×10^7cfu/g)以及&黄芪多糖(220mg/kg)+益生菌剂(4×10^7cfu/g)&。

Funecide is one of the agricultural antibiotics having intensive nematocidal activity on Meloidogyne spp.. Through the toxicity determination of six synergists(TPP, DEM, PEG, NT, H3BO3, Tween-20)to funecide indoor, we found that three of them(TPP, PEG, and H3BO3) have increased synergistic effect.

菌线克是一种用于防治线虫的新型农用抗生素，以根结线虫为靶标，通过室内毒力测定6种增效剂(TPP、DEM、PEG、NT、H3BO3、吐温-20)对菌线克的增效作用，筛选出3种增效剂单剂(TPP、PEG、H3BO3)的增效效果明显。

The Plant tissue raise is the plant sterile culture technology, has the totipotency theory according to the vegetable cell, the use plant body exsomatize organ (for example root, stem, leaf, stem point, flower, fruit and so on), the organization (for example cambium, epidermis, cerebral cortex, marrow department cell, endosperm and so on) or the cell (for example big spore, small spore, somatic cell and so on) as well as the protoplast, in aseptic and suitable artificial culture medium and illumination, temperature and so on under artificial condition, can induce injuries the organization, not to decide the bud, the adventitious root, finally forms the complete adult plant the discipline.

植物组织培养即植物无菌培养技术，是根据植物细胞具有全能性的理论，利用植物体离体的器官(如根、茎、叶、茎尖、花、果实等)、组织（如形成层、表皮、皮层、髓部细胞、胚乳等）或细胞（如大孢子、小孢子、体细胞等）以及原生质体，在无菌和适宜的人工培养基及光照、温度等人工条件下，能诱导出愈伤组织、不定芽、不定根，最后形成完整的植株的学科。
