Results showed that the root colonization rate of S. gracilis (62.2%) was higher than that of A. conyzoides (36.5%) and P.notatum (37.3%).The arbuscule percentage showed a similar pattern. Although the biomass and P content in the shoots of the three grass species were comparable, P content in S. gracilis roots was higher than that in A. conyzoides and P. notatum roots. The species richness and hyphal density in the rhizosphere soil of S. gracilis plants were less than those of A. conyzoides and P. notatum plants, while the spore density was highest for A. conyzoides and lowest for P. notatum. Diversity index of the native AM fungi in the rhizosphere soil of P. notatum plants was slightly higher than those of S. gracilis and A. conyzoides plants. PCRDGGE analysis was consistent with the morphological results.

结果表明,柱花草根系的侵染率(62.2%)显著高于百喜草(36.5%)和藿香蓟(37.3%),丛枝率有相似的趋势;3种草地上部的生物量和含磷量没有差异,但是柱花草根系含磷量显著高于百喜草和藿香蓟;柱花草根际土壤中AM真菌的菌种丰度和菌丝密度均小于百喜草和藿香蓟,但是孢子密度大于藿香蓟而小于百喜草;藿香蓟根际土著AM真菌群落的多样性指数略高于柱花草和百喜草;PCR-DGGE分析结果与之吻合。

Has also been considered during the revision.More than 1,100 specimens from 11 herbaria worldwide have been examined. After having studied the characteristics, phenology and ecological habit, we have gotten the morphological figures of each species. The characteristics of the disputed species have been studied in detail and have been quantitatively analyzed though scatter-map.

查阅和借阅了2个国家11个标本馆1100余份南五味子属标本,对世界范围的南五味子属种类作了整理,描绘了每个种的性状特征、物候期、生态习性,绘出了形态线描图,讨论了与其近缘属种间的关系;对在分类学上有争议的种类进一步进行解剖和测量,详细记录枝、叶、花、果实、种子等的形状、大小、数目、颜色、毛被等数据或信息,绘制散点图,对各种性状作定量研究,进行分析、归纳与分类。

Six bacteria and five mildews have been separated from 119 strains, wliich grew well on the culture media contained lignin. The result of taxonomic identification is that XI, X2 and X3 belong to Pseudomonas, X4 and X5 belong to Xanihomonas, X6 belongs to Mycoplana. A preliminary study has been carried out on the capacity of lignin degradation of the 6strains of bacteria, and strains X2 and X4 were chose to carry out the experiments. The most favorable temperature for the 2 strains is 30癈, and the pH is 7; After being treated by ultraviolet rays, activity of all the three kinds of lignin-degrading enzyme produced by the strains can be increased greatly, the bacteria increasing rate is remarkably improved.

从119个菌株中分离筛选出了6株细菌和5株霉菌,它们可以在含有木质素的培养基上良好生长:细菌分类学鉴定结果为X1、X2和X3:假单胞菌属,X4和X5:黄单胞杆菌属,X6:枝动杆菌属;对6株细菌降解木质素性能进行了初步的研究,选定X2和X4为实验用菌种,两株菌适宜的生长温度为30℃,最适初始pH值为7;经紫外线照射诱变法处理,可使它们产生的三种木素分解酶活性均有明显的提高,细菌增长速率比诱变前明显提高。

The results showed that the architecture of seedlings was modified plastically in response to different light conditions.
