1. There are some filamentous endophytic fungi living in darnel (L. temulentum) and producing temuline which results in the nerve system poisoning or death of human being and live stocks. 内也存在丝状内生真菌，产生毒麦碱，引起人和动物神经系统中毒，严重的甚至会死亡，同时能诱发部分黑麦草属植物发生盲种病。
2. Hybrid Bluegrass (Poa arachnifera×P. pratensis), Perennial Ryegrass (Lolium perenne) and Tall Fescue(Festuca arundinacea) were the high-value use. 使用价值高的是杂交早熟禾、多年生黑麦草和高羊茅；
3. Ryegrass (Lolium L. ), a graminaceous crop, is one of the most important grasses for forage and turf, and widely distributes in temperate regions. 黑麦草是重要的牧草和草坪草，是畜牧业和草坪业重要的产业支柱。
4. Furthermore, the prospects of RNA interference in Lolium genetic improvement and functional genomics are discussed. 并分析了功能基因组学的研究及RNA干扰技术在黑麦草研究中可能的应用前景。
5. Hybrid Bluegrass (Poa arachnifera×P. pratensis), Perennial Ryegrass (Lolium perenne) and Tall Fescue(Festuca arundinacea) were the high-value use. 使用价值高的是杂交早熟禾、多年生黑麦草和高羊茅；
