The use of herbicides leads to severe damage, especially to the environment. The aim of this investigation was operated to study the allelopathic effect of Calotropis procera, Hyoscyamus muticus and Pulicaria undulata aqueous extracts on the seed germination of Portulaca oleracea and Chenopodium murale.
The aerial parts of the plants (Calotropis procera, Hyoscyamus muticus and Pulicaria undulata) washed well in distilled water and were dried in room temperature then ground to fine powder. Aqueous extract was prepared using distilled water.
In this study, different concentrations of plant extracts (1, 3 and 5%) were used to illustrate which of these concentrations have the potential to inhibit seed growth of Portulaca oleracea and Chenopodium murale. Concentration of 5% for all plant extracts used to inhibited the growth of all seeds of Chenopodium murale while, concentration of 5% for Pulicaria undulata extract only inhibited the growth of all seeds of Portulaca oleracea.
This work dealt with the use of allelopathy strategy in preventing the growth of some weeds to be one of the safest alternative ways of using herbicides. The results showed the effective effect of plant extracts for both Calotropis procera, Hyoscyamus muticus and Pulicaria undulata on the seed germination of Portulaca oleracea and Chenopodium murale.
除草剂的使用会导致严重的破坏，特别是对环境的破坏。本研究旨在研究大猪毛七、曼陀罗和皱叶酸模水提物的化感作用对马齿苋和猪毛菜种子萌发的影响。
将植物的地上部分（大猪毛七、曼陀罗和皱叶酸模）用蒸馏水洗净，在室温下干燥，然后研磨成细粉。用水制备水提物。
在本研究中，使用不同浓度的植物提取物（1%、3%和 5%）来表明这些浓度中哪些具有抑制马齿苋和猪毛菜种子生长的潜力。所有植物提取物的 5%浓度均抑制了猪毛菜所有种子的生长，而皱叶酸模提取物的 5%浓度仅抑制了马齿苋所有种子的生长。
本工作涉及利用化感作用策略来防止一些杂草的生长，这是替代使用除草剂的最安全方法之一。结果表明，大猪毛七、曼陀罗和皱叶酸模的植物提取物对马齿苋和猪毛菜的种子萌发均有有效作用。
