Title : The allopathic effect of aqueous extract of tuberous root of (Ranunculus ficaria) on wheat seedlings growth

Abstract:

Recently, lesser celandine (Ranunculus ficaria), an invasive weed growing in high density, has decreased wheat yield in some fields of Lorestan province. An experiment was conducted in a completely randomized design with four replications to investigate the allelopathic effect of the aqueous extract of tuberous root of (Ranunculus ficaria) on wheat seedlings growth. The treatments included control (distilled water), 4, 10, 20, 40 and 80 grams of dried tuberous root per liter distilled water. The seedlings of wheat were harvested at five leaf-stages, and then root and shoot length and their dry weigh were measured. Results showed that stem length of wheat seedlings decreased from 25 cm for control to 17 cm for 80 g. Lit-1 with increasing aqueous extract concentration. The highest (24 cm) and lowest (19 cm) long roots, was observed in the control (distilled water) and 80 grams per liter, respectively. Shoot dry weight was also reduced with increasing the concentration of aqueous extract of tuberous root, and the decreasing rate of the root dry weight was higher than reduction of the stem length. The weight of wheat roots was 0.04 g at the concentration of 80 grams per liter, while its weight was 0.08 g in the control.
