İki tarla bitkisinde Euphorbia hirta ve PEG 6000 ile oluşan engelleyici etkilerin karşılaştırması üzerine bir ön çalışma

Euphorbia hirta is commonly found in all tropical regions of the world, as invasive weed with an adverse effect on other plants. The current study features two important aspects: (i), Effects E. roots exudates (0, 50, 75 and 100% concentrations) (ii), Influence PEG 6000 “Polyethylene glycol” (8, 16 40 g/l germination growth criterion Cicer arietinum (Chick pea) Phaseolus vulgaris (French bean). In this regard osmotic potential solutions have been balanced. It observed that root leachates spurge significantly (p < 0.05) affected rate while has no positive or negative activity. parameters both crops altered by highest inhibition was recorded length (3.5 cm) C. which contrast to (11.97 cm), might be due presence allelochemicals. prescribed treatments also raised their pH values, where (7.9) obtained from induction relatively a stronger basic nature rather than neutral control samples. Comparative studies test shows appeared more influential P. vulgaris. Two-way ANOVA produced significant difference between effects within group (concentrations each treatment) are weakly 0.1) other. This would intimates strongly emerged allelopathic response plants (Euphorbia hirta) exudates.
