Examine carbon sequestration potential and water use efficiency as influenced by turfgrass species and management practices. Determine irrigation requirements for salinity management on turfgrass. Develop integrated management practices for weed control in turf.
DNA from individually karyotyped plants will be extracted and sent to Diversity Arrays Technology in Australia for analyses to establish which markers co-segregate with which segment.
This will be done in both populations, for verification of results. We expect to end up with sets of DNA markers for each segment of F. Working with Diversity Arrays Technology and as described by Wenzl et al. Results will be published in Crop Science or a similar refereed journal of plant breeding and genetics.
Our approach using DArT will yield the most information in the least amount of time and for the least amount of financial investment. Furthermore, DArT markers associated with agronomic and stress resistant traits will be converted to PCR-based markers for turfgrass breeders to choose from and add to their toolkits.
Both transformation vectors carry the same b-glucuronidase gus reporter gene under the regulation of the CaMV 35S constitutive promoter, but the selectable marker gene in PBI is nptII for kanamycin resistance and in pCambia it is hpt that confers hygromycin resistance.
Shoots will be transferred to root induction medium Bajaj et al. Objective 2 - Examine carbon sequestration potential and water use efficiency as influenced by turfgrass species and management practices. Ece 355 wk 5 power point upon our preliminary research inbeginning in May we will commence bi-weekly measurements on the following species and cultivars under deficit irrigation according to physiology C3 vs.
Baseline measurements of gas exchange and soil properties will be taken under non-limiting irrigation. In conjunction with the aforementioned study, we will also estimate photosynthesis and water use efficiencies in commonly managed turf landscapes around Riverside, CA.
This analysis will survey 10 distinct owner plots of golf course, institutional, urban park, and residential in both the winter and summer of This analysis will provide information on ranges of turf growth rates compared to expectations from our field plot research.
In subsequent years, we will conduct a similar survey study, however here we will survey turf along the strong climate gradient associated with the coastal to inland transect in Southern California.
Here we will pick representative turf from the Pacific Ocean through the Coachella Valley for surveys. This research will extend our research database by examining the effect of climate on turfgrass function. Objective 3 - Determine irrigation requirements for salinity management on turfgrassIn this research project, we will examine under controlled conditions, the response of perennial ryegrass to irrigation water salinity as related to four irrigation water regimes leaching and provide recommendations regarding leaching as related to irrigation water salinity.
The experimental design will consist of irrigation treatments with four different quantities of water 1. The different quantities of water will be applied by selection of four appropriate sprinkler nozzles.
We will also apply two different water qualities, EC 1. Using sprinklers with overlapping coverage, but with water application that decreases with distance from the sprinkler, will enable a continuous distribution of salinity from 1.
Treatments will produce a set of conditions where salinity in the root zone will vary as related to the quantity of leaching water applied. We will have four water treatments with at least four salinity strips parallel to the sprinkler line, with at least two replications.
Irrigation will be applied once daily based on weather station ETo with loamy sand soil irrigated by sprinklers. During the course of the study, turf performance will be evaluated at approximately weekly to monthly intervals based on various parameters such as rate of stand establishment, blade length, sward area and volume development, leaf firing percentage, turf quality, disease incidence, and biomass production.
Clippings will be collected from each plot using a walk-behind greens mower at approximately three-week intervals, dried at 70C for 72 hours to determine clipping yield dry weight and leaf water content. In addition, we will install water extractors and other soil measuring devices at two depths in each of the main plot areas to evaluate soil water and salinity in cross sections from one line sprinkler to another.
We will evaluate the data from our experiment using the SWS computer model predictions.
The model will provide water uptake weighted salinity and calculated leaching fractions that consider the predicted decrease in ET. We will utilize the data collected from the plots of the current experiment. The response of turfgrass to salinity and leaching will be compared to the model predictions and the existing leaching guidelines.
We expect that the results will confirm that the guidelines greatly overestimate leaching needs under saline conditions. More importantly, we expect that the leaching response can be predicted using the model response functions and used to develop improved recommendations.
This research will help to develop new guidelines and recommendations regarding irrigation of turf with waters of elevated salinity. These recommendations will be based, for the first time on actual turf response to the varying irrigation and salinity regimes.
In contrast, present leaching recommendations and turf response to different leaching regimes are based on extrapolation from uniform root zone salinity data.
Objective 4 - Develop integrated management practices for weed control in turfField studies will be conducted on golf courses in northern and southern California to evaluate methiozolin and amicarbazone herbicides that are under development for selective annual bluegrass control in turfgrass.Practically Speaking, East-West Church & Ministry Report, 1 (Summer ), Written permission is required for reprinting or electronic distribution of any portion of .

In this Review we delve into the underlying causes of health disparities between Indigenous and non-Indigenous people and provide an Indigenous perspective to understanding these inequalities.
We are able to present only a snapshot of the many research publications about Indigenous health. Our aim is to provide clinicians with a framework to better understand such matters. ECE Week 5 Final Project Director’s Presentation.
