温带高产草原通常位于降雨量高、容易发生洪水的地区，但即使在这里，中度夏季干旱也会经常发生，导致产量大幅下降。需要能够抵抗水过剩和缺水的草原。采用替代育种技术将黑麦草品种和羊茅品种的理想性状结合起来，并通过增强根系来改善土壤结构和水文。双倍体L.多年生×F。与亲本品种相比，草地早熟品种可以显着减少降雨径流。有证据表明，这是由于最初的根系生长密集，随后根系广泛衰老。这似乎改变了土壤结构，增加了土壤孔隙度和保水性，通过对抗强降雨后的径流和增加干旱期间的土壤水供应来提供生态系统服务。
Temperate productive grasslands are often located in areas of high rainfall prone to flooding, but even here moderate summer droughts occur with regularity causing significant yield reductions. Grasslands capable of resisting both water excess and deficit are required. Alternative breeding technologies are employed to combine asFestuloliumcultivars the desirable traits ofLoliumandFestucaspecies, and also through their enhanced root systems, improve soil structures and hydrology. An amphiploidL. perenne×F. pratensiscultivar can significantly reduce rainfall runoff compared to either its parental species. Evidence suggests this was due to an initial intensive root growth followed by extensive root senescence. This appears to alter soil structure and increase soil porosity and moisture retention providing an ecosystem service by both combating run-off subsequent to heavy rainfall and increasing soil water supply during dry periods.
