The effects of corn pollen and aqueous leachates of pollen upon the radicle growth ofBidens pilosa, Cassia jalapensis, andRumex crispus are shown. Extractions of pollen with various solvents and methods were carried out so as to assess its active principle and its effect uponC. jalapensis. The preliminary steps to separate and identify the allelopathic compounds of the sonicated and macerated pollen extracted with methylene chloride are described. The strongest inhibitory effect was produced by the hexane fraction. The allelopathic effect of corn pollen upon the growth ofC. jalapensis in several substrates is shown. The possible structure of some of the active fractions is discussed as well as the possibility that the allelopathic potential of pollen might actually occur in nature.
玉米花粉和花粉水提物对鬼针草、瓜拉那和酸模的胚根生长的影响。为了评估其活性成分及其对瓜拉那的影响,采用各种溶剂和方法对花粉进行了提取。描述了用亚甲基氯提取的超声和粉碎花粉中分离和鉴定化感化合物的初步步骤。正己烷馏分的抑制作用最强。玉米花粉对几种基质中瓜拉那生长的化感作用也得到了证实。还讨论了一些活性馏分的可能结构,以及花粉的化感潜力在自然界中实际存在的可能性。
