| 摘要： | Annual ryegrass (Lolium multiflorum) is not currently recommended by TxDOT as a roadside re-vegetation nurse crop because its late maturity and height are too competitive for establishing perennial or spring plant mixtures. Two available genotypes used for turf that could be seeded with perennial grasses/legumes and annual wildflowers are Panterra V and Hanamiwase. Panterra V is turf-type annual ryegrass developed for home lawns while Hanamiwase is an early maturity annual ryegrass that produces seed in February and March. Both the turf-type and early-maturing annual ryegrasses could be less competitive for nutrients, moisture, and sunlight while providing adequate cover. Appropriate warm-season perennial grasses/legumes and wildflower mixes specified by TxDOT were planted as treatments in each of four regions (Beeville, Overton, Nacogdoches, and Stephenville) to evaluate these annual ryegrass genotypes, seeding rates, and mowing influences. Additionally, similar treatments were installed at five locations in a roadway implementation trial. The turf-type and early-maturing ryegrasses proved to be both competitive and persistent when used as nurse crops for warm-season perennials with mature heights similar to the annual ryegrass varieties used in the past. |
