| 摘 要： | 研究了禾本科7 个属35 个草坪草品种对禾谷缢管蚜〔Rhopalosiphum padi (L. ) 〕的抗性, 鉴定出高抗品种15 个, 中抗品种3 个, 低抗品种2 个。匍匐翦股颖( Agrostis stolonifera L. ) 和野牛草〔Buchloe dactyloides (Nutt. ) Engelm. 〕抗性最好, 均为免疫级。其次是狗牙根〔Cynodon dactylon (L. ) Pers. 〕, 6 份材料中, 有4 份属于免疫级。高羊茅( Festuca arundinacea Schreb. ) 在免疫至低抗间变化, 草地早熟禾( Poa pratensis L. ) 在高抗至中感间变化。结缕草( Zoysia japonica Steud. ) 为低感、中感水平。多年生黑麦草(Lolium perenne L. ) 抗性最差, 10 份材料均为高感。症状分析、虫口数量与受害程度关系分析初步表明,草坪草对禾谷缢管蚜的抗性包括抗生性和耐害性。

| Abstract: | Resistance to birdcherry aphid 〔Rhopalosiphum padi (L. ) 〕in 35 turfgrass varieties from 7 genera in Triticeae was studied. 15 high resistant , 3 middle resistant and 2 low resistant varieties were identified. Both creeping bentgrass and buffalograss have the best resistance and are in immune level . 4 of the 6 bermudagrass varieties are also immune from the pest . Resistance in tall fescue varieties varied from immune to low resistant and Kenturky bluegrass from high resistant to middle susceptible. Zoysiagrass exhibited low or middle susceptible resistance level . Ryegrass varieties , however , are all high susceptible to the pest . The analysis of the symptom and the correlation between aphid density and plant injury degree suggested that antibiosis and tolerance contribute to the resistance in turfgrasses to the insect . |
