Welcome to Delaware State University’s Annual Summer Research Symposium, and thank you for attending! Our symposium represents the culmination of students’ summer experiences in research at Delaware State University. This event showcases the work of college students working on faculty-led research projects, as well as middle and high school students experiencing research for the first time working in research groups. Whatever the case, this summer has been a unique experience for the students, and we hope a transformative one.  Even for students who are not planning a career in scientific research, their summer experience has given them skills they will draw on for years to come. 
<br><br>Please join us on the mainstage and in Gather for the live event, and visit the recorded poster presentations any time.
<br><br>The student participants and organizers of the various summer programs at DSU would like to thank all of the research mentors who guided our summer program participants. There were many DSU faculty, graduate students, and other research and program staff who gave their time and energy to help our students have a fun and educational summer experience. Without their generosity and patience these summer programs would not be possible.
<br><br>For the research participants, we hope that you will maintain contact with your research mentors and colleagues.  Science is a relatively small community made up of disciplinary “neighborhoods”. If you continue to work in a discipline, the other folks in that discipline will be like your neighbors that you run into regularly. Staying in contact with them will help you keep up with the news of the neighborhood, and open doors to educational and career opportunities. Whether you continue in science or take a different career path, for this summer you have been part of the world of research, and you will benefit from that perspective for the rest of your life.

Blueberries (Vaccinium corymbosum L.) are a very important crop because of their unique health benefits. The major hurdle for growing blueberries is the pH in the soil, as they need acidic soil. Hence improving the pH level tolerance in the blueberries provides a viable option for the growers to cultivate in a wide range of soil types and allow them to grow in several regions of the world. With this, our objective of the study was to screen the blueberry germplasm variation for high pH levels and identifying the tolerant lines. We used an in-vitro plant twig assay to screen the population using phosphate buffer solutions containing several pH gradients ranging from 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, and 7.0. In the assay, we used 6 different varieties of blueberries for testing the variation for pH level. Among six varieties, we screened, identified one highly resistant, 4 moderately resistant genotypes, and one sensitive genotype to the high pH. The resistance lines maintained a stay green nature at the high pH level, but the sensitive lines turned to brownish and chlorophyll degradation was observed. Developing new cultivars for high pH tolerance requires the effective identification of tolerant blueberry genotypes; therefore, the current approach was aimed at evaluating blueberry genetic resources under laboratory conditions by establishing an invitro plant twig assay. This assay provided an easy and time-consuming method to identify the blueberry genotypes tolerant to high pH and a better genetic source for developing the pH tolerant varieties.
