Title

EFFECT OF SUNFLOWER (HELIANTHUS ANNUUS) LEAF ALCOHOLIC EXTRACT ON GERMINATION, VEGETATIVE GROWTH, SOME ENZYMES ACTIVITIES OF WINTER WILD OAT (AVENA LUDOVICIANA) SEEDLING

Pages

Abstract

 Chemical herbicides are the key component of weed control in agriculture but have adverse effects on environment. In order to evaluate the allelopatic potential of sunflower alcoholic extract against winter wild oat (Avena ludoviciana) at germination and vegetative growth stage, two experiments were conducted. Experiments were laid out according to Completely Randomized Design with five replications and treatments with various concentration of sunflower extract (0, 5, 10, 15 and 20 gr L-1). Results indicated that sunflower alcoholic extract application exhibited gradual rise inhibitory effect on seed germination, seedling weight, ANTIOXIDANT ENZYMEs activity and a-amylase enzyme activity but elevated the mean germination time and MALONDIALDEHYDE concentration in winter wild oat seedlings. The lowest a-amylase enzyme activity was noted at higher levels of extract application (1.1 nmol seed-1 min-2), Likewise, seedling weight, ANTIOXIDANT ENZYME activities and sucrose synthetesis enzymes activity were declined with sunflower extract application but MALONDIALDEHYDE concentration was increased. Minimum sucrose synthesis activity (1.36 nmol prot -1 min-2) and highest MALONDIALDEHYDE concentration (0.96 nmol grfw-1) were noted at 20 grL-1 concentration of sunflower al c oholic extract application. In conclusion, sunflower alcoholic extract decreased seed germination, seedling growth, a-amylase enzyme and sucrose synthetesis enzymes activity of winter wild oat.
