Abstract

The allelopathic potential of Eucalyptus camaldulensis and Citrus aurantium were investigated against Triticum aestivum L. (Var. Gomal) in the laboratory. Fresh and dry leaves (5, 10 and 15g) of E. camaldulensis and C. aurantium were soaked in 100ml of distilled water for 24hrs and 48hrs and were then filtered. The extract was then applied on Triticum aestivum to investigate the allelopathic impact on germination percentage, radicle and plumule length after 72hrs of incubation period at 26°C. The results showed that the fresh and dry leaves extract of E. camaldulensis and C. aurantium significantly reduced the plumule and radicle length and showed a lesser effect on the germination percentage of Triticum aestivum as compared to the control. The germination percentage was effected more by 48hrs soaking duration extract of E. camaldulensis than C. aurantium and was recorded 24.26%. The radicle length was effected more by 48hrs soaking duration extract of C. aurantium as compared to E. camaldulensis and was recorded 77.23%. The plumule length was effected more by 24hrs soaking duration extract of E. camaldulensis as compared to C. aurantium and was recorded 91.68%. From the results, it was concluded that the dry and fresh leaves extract of C. aurantium and E. camaldulensis significantly effected the growth and germination percentage of Triticum aestivum which suggests that some allelochemicals might be present in C. aurantium and E. camaldulensis.

山梨树和金柑水提液对小麦萌发和生长的化感作用

在室内研究了桉木和金柑对小麦的化感作用。鲜叶、干叶(5、10、15g)分别在100ml蒸馏水中浸泡24h、48h后过滤。在26℃条件下培养72小时，研究其化感作用对小麦发芽率、胚根和胚粒长度的影响。结果表明，与对照相比，鲜叶提取物和干叶提取物显著降低了小麦胚珠和胚根的长度，对小麦发芽率的影响较小。浸渍时间为48h的山梨花浸渍液对发芽率的影响最大，为24.26%。浸提48h对根长影响较大，达77.23%;浸渍时间为24h的山梨花浸渍液对子叶长度的影响最大，达到91.68%。综上所述，金菖蒲和山菖蒲干叶提取物和鲜叶提取物对小麦的生长和发芽率均有显著影响，说明金菖蒲和山菖蒲中可能存在一定的化感物质。
