Potential Allelopathic Effect of Wheat Straw Aqueous Extract on Bermudagrass Noxious Weed

Residues of several crops, including wheat, have a promising allelopathic effect on noxious weed species and thus represent eco-friendly alternatives to harmful, widely applied herbicides. The current investigation deals with the effects wheat straw aqueous extract growth biochemical aspects bermudagrass (Cynodon dactylon L.) as model harmful weeds for crop. prepared from was subjected high-performance liquid chromatography (HPLC) analysis identify quantify phenolic flavonoid components. In addition, different concentrations germination, seedling growth, assessed. Our findings showed significant decrease in seed germination percentage (ranging 29.6 82.4%) index 10.07 32.43) response treatments decline all morphological parameters seedling. HPLC presence seven acids six flavonoids. most prevalent phenolics included pyrogallol (13.75 µg/g), ferulic acid (9.82 gallic (8.5 isoferulic (4.47 while predominant flavonoids catechin (11.04 luteolin (8.26 µg/g) quercetin (7.74 µg/g). highest (75% 100%) corresponding leaf content chlorophylls b but increase free amino acids, total protein soluble carbohydrates. Superoxide dismutase (SOD) activity exposed concentration-dependent reduction, activities both catalase (CAT) ascorbate peroxidase (APX) were reduced only concentration. principal component (PCA) high correlation among parameters, indicating that these elements either common ground variance or are inter-correlated. Accordingly, our suggest possibility combating using straw.
