| Abstract/Contents: | Discusses the effect perennial ryegrass overseeding has on spring transition, stating that "increased disease resistance, tolerance to frequent and close mowing, abundant tillering capacity, and increased heat tolerance make for better and stronger ryegrass turf. This is a major liability for spring transition, however. Transition conditions may exhibit any of the following conditions: 1. Prolonged persistence of ryegrass into July and August. 2. Prolonged persistence followed by sudden loss of ryegrass cover. 3. Loss of ryegrass cover without adequate regrowth of bermudagrass from below." Presents a study to "evaluate the effect of overseeding rate on turfgrass canopy dynamics, and to determine if seed rate and canopy dynamics were associated with spring transition." Results include: "1. The accepted adage that increased rates of perennial ryegrass will cause weaker plants was generally true. Based on cell electrolyte leakage tests, plants that grew at higher seeding rates had decreased tolerance. 2. However, heat tolerance was not related to transition - berudagrass amounts in plots did not increase as seed rates increased. In fact, the opposite generally occurred. The highest seed rate (800 lbs.) always had the least amount of bermudagrass present, while the lowest overseed rate (450 lbs.) had the largest amount of bermudagrass. 3. Overseeding rates of 450 to 500 lbs. and from 600 to 700 lbs. provided the best transition and acceptable turfgrass conditions. 4. Overseeding at 800 lbs. greatly reduced transition in this test. 5. All treatments, in time, returned to 100% bermudagrass, in the same ranked order based on the percentage reported for transition in June." |
