Abstract

Crop plants release biochemicals into surrounding environment that help in obtaining maximum yield of crop by acting bioherbicide at high concentration and plant growth hormone at low concentration. Therefore, this study was planned at Department of Agronomy in Weed Science Laboratory, University of Agriculture Faisalabad during Winter 2018 to evaluate the allelopathic effects of A. officinalis on weed Wild Pea (Pisum sativum subsp. elatius). The experiments were laid out under completely randomized design (CRD) having three replications. The aqueous extracts of C. verum. were used on radish and wild pea seeds at different concentrations (2.5%, 5%, 10%, 20%, 40% and 80%). Data regarding seed germination and seedling growth (shoot length, root length, shoot fresh weight, root dry weigh) of weed were recorded following standard procedures. Results Reveals that the aqueous extract of A. officinalis at higher concentration (80%) act as bioherbicide and produced inhibitory effects on R. sativus result in Maximum time to 50% germination (6.70 days) and mean germination time (10.00 days) while minimum germination index (4.70), germination percentage (66.60%), shoot length (49.8 cm), root length (8.16 cm), shoot fresh weight (10.00g) and root fresh weight (10.361g). While at lower concentration (10%) it shows hermetic effect and produce maximum germination percentage (90.00%), shoot length (84.7 cm), root length (66.2 cm), shoot fresh weight (82.20 g), root fresh weight (58.30 g) and germination index (8.21%) minimum time to complete 50% germination (4.33 days) and mean germination time (5.49 days) growth. In A. officinalis among different phenolic compound minimum Syringic acid (0.60%) and maximum Quercetion (12.3%) compound was found. Therefore, it was concluded from this study that aqueous extract of officinalis can be used as growth promoter at lower concentration while at higher concentration for environmentally friendly control of weeds.

A、野生豌豆(Pisum sativum subsp.)羽化和幼苗生长的封闭势鉴定。elatius)。

作物向周围环境释放生物化学物质，高浓度作用生物除草剂，低浓度作用植物生长激素，有助于作物获得最大产量。因此，本研究计划于2018年冬季在费萨拉巴德农业大学杂草科学实验室农学系进行，以评估officinalis对杂草野生豌豆(Pisum sativum subsp)的化感作用。elatius)。试验采用完全随机设计(CRD)，设3个重复。verum的水提取物。不同浓度(2.5%、5%、10%、20%、40%和80%)的萝卜和野生豌豆种子。按照标准程序记录杂草种子萌发和幼苗生长数据(茎长、根长、茎鲜重、根干重)。结果表明，在较高浓度(80%)的条件下，马蹄草水提物具有生物除草剂的作用，对小黄菜的萌发时间最大(6.70 d)，萌发率最小(66.60%)，芽长最小(49.8 cm)，根长最小(8.16 cm)，茎鲜重最小(10.00g)，根鲜重最小(10.361g)。低浓度(10%)萌发率最高(90.00%)，茎长84.7 cm，根长66.2 cm，茎鲜重82.20 g，根鲜重58.30 g，萌发指数8.21%，完成50%萌发的最短时间(4.33 d)和平均萌发时间(5.49 d)。不同酚类化合物中丁香酸含量最低(0.60%)，槲皮素含量最高(12.3%)。因此，本研究认为，officinalis水提物在较低浓度下可作为生长促进剂，在较高浓度下可作为杂草的环保防治。
