ALLELOPATHIC EFFECT OF LEAVES ON GERMINATION OF WHEAT (TRITICUM AESTIVUM L.)

An experiment was conducted to determine the allelopathic potential of leaves of seven different plant species on germination of wheat variety Pir Sabaq 2005. The experiment was laid out in completely randomized design (CRD) with seven treatments replicated three times. The aqueous solution of leaves of seven plant species including Dodonaea viscosa (L.) Jacq., Eucalyptus camaldulensis Dehnh., Fumaria indica (Hausskn.) Pugsley, Juglans regia L., Olea ferruginea Wall. ex Aitch., Tamarix indica Willd. and Taraxicum officinale aggr F.H.Wigg. was applied for germination of wheat. Significant variation was observed among the treatments for germination attributes. Maximum (4.54 cm) radical length was observed in extract of T. officinale while minimum (1.20 cm) radical length in extract of E. camaldulensis. The highest (3.21 cm) plumule length of wheat was recorded in control, followed in extract of J. regia (2.85 cm) and the lowest (1.12 cm) in extract of E. camaldulensis. It may be concluded that leaves extracts of J. regia and T. officinale can be used for plumule and radical, respectively due to its growth enhancing effect while leaves of E. camaldulensis can be used as herbicide.
