Six days after inoculation, the cucumber root tip was slightly swollen and symmetrical root-knots were observed at the meristematic and elongation zones. Giant cells were differentiated by previous cambium cells in the center of the root; 10days after inoculation, symmetrical and secondary root-knots were observed at the root hair and upper zones. Vessels were separated by giant cells, around which protoxylem vessels were observed; l6days after inoculation, hypo-vascular tissue appeared earlier than normal; 20-30 days after inoculation, the vertical arrangement of vessels was disordered, shape was distorted and a new vascular tissue appeared in the cortex.

结果显示:接种后6 d的根尖分生区、伸长区出现膨大、对称的根结,根中心的原形成层细胞分化出巨型细胞;10 d在根毛区及以上部位出现既有对称又有偏于一侧的根结,周围有原生木质部导管出现,根结中巨型细胞阻断了导管;16 d次生维管组织提早出现;20~30 d导管纵向排列无序,形状扭曲,皮层中有新维管组织产生。

The analytical method is always used due to the large amount of the objects and not very high accuracy of forecasting.

植物从种子萌发开始,胚根从种皮中伸出并向下生长,这种从胚中长出的根称为主根,随着生长过程的进行,又会在主根上长出侧根,而当侧根长到一定的时候又会长出次一级的侧根,这样不断生长就形成了一个植物的根系。

Root out the problems and make the necessary adjustments as early as possible.

Results: The hairy root was successfully induced and the hairy root culture system was set up; The opines assay was positive for mannopine and agropine; The result of determination showed that there were a lot of anthroquinone constituents in the rhubarb hairy root and the contents of rhein, aloe-emodin, emodin or 8-O-methylchrysophanol were respectively higher than those in wild plant root.

结果:诱导出了天山大黄发根,并建立了发根离体培养系;从发根中检测到甘露碱、农杆碱的存在;定量分析发现,天山大黄发根中含有多种蒽醌类成分,其中大黄酸、芦荟大黄素、大黄素、大黄酚-8-甲醚的含量分别高于原植物根中的含量。

Or, rather, it employs two ring-shaped half-pipes that rotate with respect to one another (the lower one remaining fixed while the upper one revolves along with the building).

Ninety seven spores or sporocarps of VAMF were wet sieved from the rhizosphere soil of mycorrhized pteridophytes, from which 25 VAMF species which belonged to the genera of Acaulospora, Gigaspora, Glomus, Sclerocystis and Scutellospora respectively were identified, and the taxonomic characters of the 25 species were described. The Glomus fungi were the dominant VAMF in the rhizosphere soil of pteridophytes, they took up 44% in the identified 25 VAMF (11 species belong to Glomus); the fungi in Acaulospora and Sclerocystis in the next place, they took up 24% and 16% respectively in the identified VAMF; the fungi in the other genera took up 16%. In terms of the relationships of pteridophytes and the VAMF isolated from their rhizosphere soil, there was no specifity between the VAMF and their host.

从具有VA菌根的蕨类植物对应的根际土壤中用湿筛法筛取了97份VA菌根真菌的孢子或孢子果,从中鉴定出了分属于无醒囊霉属、巨孢囊霉属、球囊霉属、硬囊霉属和盾孢囊霉属的VA菌根真菌25种,并对这25种真菌的分类学特征进行了描述;球囊霉属真菌是蕨类植物根际土壤中的优势类群,已鉴定的25种真菌中,有11种属球囊霉属真菌,占44%,其次是无梗囊霉属和硬囊霉属真菌,分别占24%和16%,其他属的VA菌根真菌占16%,从分离鉴定的蕨类植物根际土壤中的VA菌根真菌与蕨类植物的关系看,VA菌根真菌与蕨类植物之间无明显的专一性。
