Root Exudates of Fifteen Common Weed Species: Phytochemical Screening and Allelopathic Effects on T. aestivum L.

Through allelopathic interactions, plants may either suppress competing species or promote those that help them better adapt to their environment. The purpose of this research was determine how the root exudates 15 common weeds affected germination wheat (Triticum aestivum L.). Every other day, seeds were dispersed over Petri dishes (with filter paper) and pots garden soil) treated with 1 mL 5 aqueous exudates, respectively. Distilled water had highest rate at 86.33% lowest 64.00% (p = 0.001) for Commelina benghalensis in dish containing exudates. seed percentage pot condition lowest, 68.45% 0.004), Solanum nigrum, while control 87.23%. Similarly, shoot length, 12.01 cm 0.0025) Mikania micrantha, length 2.17 0.0048) Leucas aspera, recorded, whereas 19.13 3.46 cm, respectively, dishes. In addition, growth 9.72 0.0004) micrantha 4.34 0.0019) Spilanthes acmella, 20.13 6.42 culture. Furthermore, seedlings, biomass studies T. showed elevated malonaldehyde (MDA) levels both cultures. However, chlorophyll a b levels, as well antioxidant enzymes catalase (CAT) superoxide dismutase (SOD), are lower than group. Both cultures compared grown plates. dry weight seedlings cultivated demonstrated its considerable influence. This found all studied could have capacity impede development seedlings. These inhibitory effects higher
