| 中文摘要: |
| 采用菌丝生长速率法测定6%阿泰灵（寡糖?链蛋白）WG、2%香菇多糖AS和5% 氨基寡糖素AS对火龙果溃疡病菌（Neoscytalidium dimidiatum）的抑制作用，并通过盆栽试验明确了3种诱抗剂对火龙果溃疡病的诱导抗性。结果表明，6%阿泰灵（寡糖?链蛋白）WG的抑菌效果低于10%，5%氨基寡糖素AS和2%香菇多糖AS的抑菌效果为0；6%阿泰灵（寡糖?链蛋白）WG诱导抗病性效果达到60%以上，5%氨基寡糖素AS和2%香菇多糖AS的诱导抗病性效果超过了80%，其中83.33ｍg/L的5% 氨基寡糖素AS和33.33ｍg/L的2%香菇多糖AS诱导抗病性效果分别达到89.81%和87.79%。 |
| 英文摘要: |
| Bacteriostatic activity of three elicitors agent Neoscytalidium dimidiatum were tested using mycelial growth rate menthod, this study determined the induced resistance of the 6% oligosaccharins穚lant activator protein (WG) , 2% lentinan (AS) and 5% amino-oligosaccharin (AS)．The results showed that 2% lentinan (AS) and 5% amino-oligosaccharin (AS) had no bactericidal activity，inhibitory effect of the 6% oligosaccharins穚lant activator protein (WG) was less than 10%; The results of pot experiment indicated that the effects of induced resistance of these 3 elicitors with different concentrations against pitaya in seedling stage were good．6% oligosaccharins穚lant activator protein (WG) was over than 60%，2% lentinan (AS) and 5% amino-oligosaccharin(AS) were over 80%．Among them，The better treatments were 5% amino-oligosaccharin (AS) at concentration of 83.33 mg稬-1 and 2% lentinan (AS) at concentration of 33.33 mg稬-1．Their control efficiencies were 89.81% and 87.79%，respectively． |
