• From the standpoint of soil ecology , the direct effects of allelochemicals from crop root exudates on soil biota ( bacteria , fungi , nematode etc . ) were specifically discussed , and the key function of allelochemicals from root exudates in soil was presented
  还重点列举了一些作物根分泌的化感物质对土壤生物产生的直接和间接影响，阐明了根分泌的化感物质在土壤中所起的重要化感作用。
• As allelochemicals from plant root exudates are becoming a hotspot in the field of soil ecology , such problems as the nondestructive techniques for collecting in - situ and the identification of allelochemicals from plant root exudates should be emphasized in the future
  根分泌物化感作用的研究已成为土壤生态学领域的热点与前沿课题，自然条件下原位收集鉴定植物根系分泌物中的化感物质等诸多问题是该领域今后的研究重点。
• The results showed that galium tricorne had allelopathic effects on all wheat varieties tested , but the allelopathic effects were significantly different on various wheat varieties , and the difference might he caused by the genetic traits of different wheat varieties
  结果表明，猪殃殃对不同小麦品种均存在一定程度的化感作用，但是化感作用的强度在不同小麦品种间存在显著差异，这种差异可能是由小麦品种的遗传特性决定的。
• With ri values as allelopathic index and through cluster analysis , these varieties could be divided into three groups , among which allelopathic effects of galium tricorne on xiaoyan 22 , yuanfeng 175 , xinong 979 , zhengmai 9023 and xinong 889 were relatively weak , so the five varieties had relatively strong anti weed potentials
  以ri值为化感作用的评价指标，结合聚类分析的方法，将这15个小麦品种分为3组，其中猪殃殃对小偃22 、远丰175 、西农979 、郑麦9023和西农889等5个品种的化感作用较弱，这5个品种表现出较强的抗草潜力。
• Future research should focus on : ( 1 ) to identify and purify allelochemicals more effectively , especially for agriculture , ( 2 ) the functions of allelopathy at the molecular structure level , ( 3 ) using allelopathy to explain plant species interactions , ( 4 ) allelopathy as a driving force of succession , and ( 5 ) the significance of allelopathy in the evolutionary processes
  未来化感作用研究将集焦于如下五方面： （ 1 ）更有效地在实践中，特别是在农业生产过程中鉴定和提纯化感物质； （ 2 ）化感作用在分子结构水平的功能定位； （ 3 ）应用化感作用解释植物种间相互作用； （ 4 ）化感作用在植被演替过程中的驱动力作用； （ 5 ）化感作用在进化过程中的意义。
• On one hand , the allelopathy caused by petroleum ether and ethanol extracts of s . chamaejasme leaves on the other plants germination was investigated , on the other hand , the inhibition of the 2 extracts on insects and pathogenic microorganism of crop were tested . the aim of these studies is to provide empirical foundation for the development of a new botanic pesticide
  本文从化感作用的角度出发，研究了瑞香狼毒叶石油醚和乙醇两种提取物对植物种子萌发的影响，同时研究了两种提取物对作物病原菌和昆虫生长的抑制作用，目的在于揭示瑞香狼毒叶是否具有化感作用，并为一种新的植物源农药的开发提供实验依据。
