Abstract

ABSTRACT: Dry land plants owing to their capability to grow under stressful environment have shown higher allelopathic potential as compared to cultivated plants. An experiment was conducted to investigate the herbicidal potential of aqueous extracts of four dry land plants viz. fruit and vine of Citrullus colocynthis, and above ground parts of Rhazya stricta; Crotalaria burhia and Calligonum polygonoides, with four concentrations (25, 50, 75 and 100%) of initially prepared extracts against Lathyrus aphaca, a common weed of wheat in the studied region. These plants were collected from dry land area (30.03° N and 70.38° E, 129 m above sea level, almost desert conditions) of Dera Ghazi Khan, Punjab, Pakistan. All the four plants exhibited pronounced herbicidal potential with 9 to 91% suppression of different parameters in L. aphaca). Maximum inhibition was recorded in germination (36-91%). Significant suppression in leaf count (9-65%), shoot length (12-59%), root length (4-62%), shoot fresh weight (17-71%), root fresh weight (10-60%), shoot dry weight (15-72%), root dry weight (13-64%), and nodule numbers (34-89%) was also observed. The highest inhibition was exhibited by R. stricta followed by C. colocynthis: fruit. However, in case of nodulation maximum suppression was produced by C. burhia extract. Least suppressant activity was observed for the C. polygonides extract. These results encourage the potential use of locally available dry land plants possessing strong allelochemical properties for nonchemical control of weeds ultimately reducing reliance on chemical control.

一些旱地植物对冬草蚜的除草潜力

摘要:旱地植物由于在逆境环境下的生长能力，比栽培植物表现出更高的化感作用潜力。研究了四种旱地植物(Citrullus colocynthis果实和藤、Rhazya stricta地上部分)水提液的除草潜力;用四种浓度(25%、50%、75%和100%)的初始制备提取物对研究地区常见的小麦杂草稻瘟病螨(Lathyrus aphaca)进行防治。这些植物采自巴基斯坦旁遮普省Dera Ghazi Khan的干旱地区(30.03°N和70.38°E，海拔129 m，几乎是沙漠条件)。4种植物均表现出显著的除草潜力，对稻瘟病菌不同参数的抑制率为9 ~ 91%。萌发时抑制最大(36-91%)。叶片数(9-65%)、茎长(12-59%)、根长(4-62%)、茎鲜重(17-71%)、根鲜重(10-60%)、茎干重(15-72%)、根干重(13-64%)和根瘤数(34-89%)均受到显著抑制。缢蛏的抑菌效果最好，其次为结藻菇。而在结瘤的情况下，布氏菌提取物的抑制作用最大。黄精提取物的抑菌活性最低。这些结果鼓励利用具有强烈化感化学特性的当地旱地植物进行非化学控制杂草，最终减少对化学控制的依赖。
