Abstract:
Oligosaccharide from Dalian fungi(DLO) was obtained through thermal cracking of fungal cell wall.In order to study the effects of DLO on growth traits and phytoalexin inducement of soybean,the concentration of 1,5,50 mg.L-1DLO were used to treat soybean for 4 h with seed-immersion method.The results indicated that the plants treated with DLO grew better than that of control.The efficacy of DLO increased with concentration.Under 50 mg. L-1,the stems were 5%thicker,17% higher and 2.8% heavier than that of control nine days after treatment.The inducement of DLO also increased with concentration and the OD value of 100 mg.L-1?reached 1.103.The results indicate that DLO has the effect of promoting growth and inducing phytoalexin production of soybean.
