The experimental results showed that the absence of effective pollination in wild peonies under natural conditions, especially between different populations, was an important cause for the declining of seed adaptability, and that seed epicotyl dormancy is an important intrinsic factor in its sexual cycle which aggravated the scarcity of wild peony seedlings and populations in nature.

实验证明：在自然状态下野生牡丹缺乏充分的传粉，特别是居群间的传粉不足，导致其种子质量低下；而野生牡丹种子特殊的萌发特性，特别是严格的上胚轴休眠，则是导致其出苗率极低及自然状态下幼苗和种群稀少的重要内因。

The results showed that, all the treatments can shorten the time of epicotyl germination of 'Fengdan', the 28 days chilling treatment was the shortest, and the next was 21 days chilling treatment and 300 mg/L GA3 treatment; in a certain range of GA3 concentrations, higher concentrations, higher seed germination index and germination rate in 'Fengdan'; the seed germination index and germination rate of 'Fengdan' after different time chilling treatments were higher than the control, in which, the treatment of 21 days chilling had the highest germination index and germination rate.

研究了不同时间的低温(4℃)处理及不同浓度的GA3处理对凤丹种子上胚轴萌发及幼苗生长的影响，结果表明：所有处理均能缩短凤丹种子上胚轴萌发时间，以低温28天处理初萌期最短，其次是低温21天和300mg/L GA3处理；在一定的GA3浓度范围内，浓度越高，凤丹种子发芽指数与发芽率越高；不同时间低温处理后凤丹种子发芽指数与发芽率均高于时照，其中低温21天处理是所有处理中发芽指数与发芽率最高的。

Based on the model of DLA, this paper simulates the process of aggregation's growth for random walk particles from local area on two-dimension Euclidean plane. The aggregation is confined to Euclidean circular plane for large enough particle walking area and far enough partial source distance. The centre of the Euclidean circular plane is on the line between the particle source's symmetric centre and the seed particle, and is more closer to the particle source than the seed particle. Though the rate of aggregation growth is different in different directions, the whole aggregation shows fractal structure.

以DLA模型为基础，模拟研究了在二维欧几里德平面上由局部区域内产生随机运动粒子的聚集生长过程，发现对于足够大的粒子运动区域和足够远的粒子源距离，凝聚集团大体上被限制在欧氏圆形面内，圆心在粒子源对称中心和种粒子的连线上，且比种粒子更加接近粒子源；凝聚集团朝各个方向的平均生长速率虽然不同，但整体仍呈分形结构。

To discuss the relationship between the allelopathy of native plants in Guizhou and seed germination of Eupatorium adenophorum, the method of culture dishes with filter paper was used to research effects of 10 kinds of leaf aqueous extract on seed germination of Eupatorium adenophorum.
