Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Research has extensively showed that pastures with complex composition can increase production in some situations. However, there is a general lack of information on the role of within species (intra-specific) diversity and its contribution to the ecological functionality of a community. This research used perennial ryegrass as a model plant to (i) quantify within- and between-cultivar variation of L. perenne cultivar blend BG34 on the basis of several morphological characteristics and forage yield; (ii) investigate the responses of relative yield and production components of individual genotype, and how this was affected by the treatments of genotype and defoliation; and (iv) evaluate the suitability of SSR (simple sequence repeats) and ISSR (inter simple sequence repeats) markers to differentiate the cultivars of L. perenne that comprise BG34 and investigate the genetic structure of pastures sown with BG34 ryegrass from dairy fields in Ohio. With 100 potted plants of the four cultivars investigated, within-cultivar variation accounted for 73-97 % of the total variation for the morphological traits (i.e. height, tiller number, erectness, leaf width and yield), and 13.4 to 89.9% of the variation could be attributed to genetic variation. A genotype treatment by defoliation treatment experiment was established with cloned plants of eight genotypes, which had different production and tillering potentials, it was found that plot production was linearly related to genotype diversity, and mixtures had significantly greater yield than monoculture on average. Frequent (3-wk) defoliation reduced grass yield by 12.7%, while the 60 mm height clipping reduced grass yield by 14.3%. In general, large genotypes were favored in mixtures and small genotypes were at disadvantage. With both SSR and ISSR markers, individuals of BG34 were correctly allocated to lines and cultivars with 80.9-86.7% accuracy. There were distinct differences between cultivars, suggesting the suitability of the marker systems in identification of L. perenne cultivars. Divergent changes in the proportions of the respective cultivar of BG34 were found on the three 5-year old fields in Ohio.

This book was released on 2017 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perennial ryegrass (Lolium perenne L.) is a widely grown cool season, bunch type, short lived perennial grass that is native to Europe, Asia, and North Africa, but has been adapted globally. Perennial ryegrass is quick to establish, has a long growing season, and produces high seed yield and forage or turf quality (high density, fine leaves, and dark green color). Mesotrione is a selective 4-hydroxyphyenyl pyruvate dioxygenase (HPPD) inhibiting herbicide used for weed control in perennial ryegrass seed production and turfgrass in the USA. HPPD inhibiting herbicides cause a reduction in carotenoids which protect chlorophyll from high energy light. The photodegradation of chlorophyll results in a bleaching of leaf tissue in susceptible plants. In seed production, mesotrione, commercialized in the USA as Callisto®, is applied postemergence in the spring to fall planted perennial ryegrass seed crops. Mesotrione for use in turfgrass, commercialized in the USA as Tenacity®, is applied pre or postemergence. The effects of a postemergence application of mesotrione on chlorophyll concentration, dry biomass, plant height, and seed yield and germination compared to an application of another HPPD inhibitor, pyrasulfotole-bromoxynil, on perennial ryegrass cultivars were evaluated. There were differences in perennial ryegrass cultivar response to a postemergence application of both HPPD inhibitors in chlorophyll concentration and to a postemergence application of pyrasulfotole-bromoxynil in dry biomass. No reduction in plant height was caused by the HPPD inhibitors. Seed yield of the perennial ryegrass cultivars was not negatively impacted by a postemergence application of mesotrione. However, only twelve perennial ryegrass cultivars were evaluated in this study; therefore, caution may be warranted when using mesotrione with other perennial ryegrass cultivars. The effects of mesotrione applied postemergence on perennial ryegrass cultivars at three different temperatures, 5, 25, and 35°C, on chlorophyll concentration, leaf color, and total chlorophyll were investigated. At each temperature, there was a response within some cultivars. The cultivar ‘Derby Xtreme’ exhibited the most sensitivity to mesotrione at 5°C and ‘SR 4660ST’ was the most sensitive at 35C. The cultivar ‘PR 8821’ was the most sensitive overall at all evaluation timings and temperatures. The cultivar exhibiting the most tolerance to mesotrione was ‘Esquire’. Assessing perennial ryegrass cultivar response to mesotrione at one temperature versus another temperature resulted in ‘Allstar 3’ exhibiting less sensitivity at 35 than at 5 or 25°C. The majority of cultivars exhibited more sensitivity at 25 than at either 5 or 35°C. Turfgrass managers should use caution when applying mesotrione postemergence to some perennial ryegrass cultivars if temporary bleaching of the turf is undesirable.
