Dear ASHS–10 Conference Attendees, Welcome to the 107th Annual Conference of American Society for Horticultural Science, which is being held August 2–5 at the lovely Desert Springs JW Marriott Resort and Spa, located in Palm Desert, California. I understand that the Desert Springs Resort recently completed some fabulous renovations that include an impressive new porte-cochere that is the gateway to hotel’s new lobby, complete with smooth-flowing guest registration, a magnificent new 60-foot bar with a backdrop of cascading water, and the desert’s coolest new sushi bar. From the hotel’s impressive lobby you can enjoy the breathtaking views of the mountains. It is a lush exotic oasis amid pristine desert, where you can enjoy two 18-hole golf courses, spa, 4 signature restaurants, a high-energy nightclub, sparkling pools, shopping and more. What an opportunity to hold our Annual Conference in such a magnificent setting and it is a wonderful opportunity to fulfill my personal philosophy on planning meetings such that they have a “delicate blend of educational opportunities and entertainment.” The conference committee along with the ASHS Headquarters staff has done an excellent job of organizing the conference which is filled with many great workshops, colloquia, poster and oral sessions.. The working groups have again proven that they are the spark plugs of the society’s engine by organizing 31 workshops that cover the waterfront of horticultural topics. In addition there are two excellent symposium being offered: one on “Current Issues and Applications in Horticultural Intellectual Property” and the second on “Microirrigation Technology”. The meeting also has the 23rd William A. “Tex” Frazier lecture being presented by Dr. Henry Thompson, Director of the Cancer Prevention Laboratory, Colorado State University. The 2010 B.Y. Morrison Memorial Lecture “Developing Strategies for Sustainable Production in a Changing Global Climate Scenario: Merging Physiological and Genetic Approaches” is being presented by Dr. Jiwan Palta, University of Wisconsin, Madison. At the Opening Plenary Session we will also present the Publication Awards, Career Awards, Student Scholars, and induct our newest class of ASHS Fellows. The Welcome Reception is a great time to renew old friendships and make some new friends and catch up on the latest news and views. The Annual Extension Banquet is back and offers a chance for some fun and socialization regardless of your academic appointment. The meeting offers an excellent opportunity for undergraduate and graduate students to become more involved in the organization and a chance for networking both for graduate school opportunities as well as jobs after graduate school. The meeting is jammed packed with both intellectual and social activities and some excellent tours thrown in all at the right price thanks to the efforts of Mike, Tracy, and the dedicated staff at ASHS. I believe we are on the road to having a great meeting in wonderful location! We are really thrilled that you have elected to join us in sunny Palm Desert, California, and we look forward to your participation in the conference.

E. Barclay Poling views horticultural industry problems as opportunities. As a new assistant professor, he began to critically examine the relative com- petitiveness of the North Carolina matted-row strawberry industry. From the beginning, he took advantage of opportunities and to see firsthand the world’s E. Barclay Poling most technologically advanced strawberry industries and to work with such North Carolina State University strawberry ‘gurus’ as Southern California’s Victor Voth. This motivated him to pursue a research agenda with the goal of identifying a strawberry growing system that would allow North Carolina farmers to successfully compete in fresh markets with California plasticulture strawberries—something that was clearly beyond the industry’s reach because its smaller matted-row berries were too-cost prohibitive to pick for the fresh market. Fast forward through about 25 years of well-documented research and extension reports of the different adaptations of the plasticulture growing system that were made to adapt annual hill plasticulture methods to state’s 3 climatic Awardees regions (coastal plain, piedmont, mountains)—and what has been learned is that the plasticulture growing system, and cultivars like ‘Chandler’ work espe- will be cially well for direct marketing!

Plasticulture has also proven to be a tremendous boon for off-farm, “pre-pick” markets that during the include roadside stands, farmers markets, and supermarkets specializing in fresh, locally grown produce. Barclay Poling’s innovative research and exten- Opening sion program has created an opportunity for a virtual sea-change in how fresh, red-ripe strawberries are being grown and locally marketed in North Caro- Plenery lina and throughout the Mid-South today.

USDA Monday, statistics show that North Carolina farmers have been able to utilize plasticulture technology to increase average strawberry yields by 470 lbs/acre/yr from August 2, 1991 to 2008. Poling’s strawberry research achievements and outstanding service to industry have been widely recognized as he has been the recipient of 10:00 am, in many notable awards including The Pioneer Award of the American Society for Plasticulture, the SR–ASHS H.M.

According to Katherine C. Sozansky, “Like many students, I spent the first years of college pursuing interests, trying to find something to make college—and life—more worthwhile. I jumped from anthropology to psychology to nutrition, all in hopes that I would find a passion that I could pursue for the rest of my life. Outside of school, I became very interested in my own health and health in general. I read many books about nutrition science, but as I pur- sued a degree in nutrition, I still felt that something was missing.” She adds, “When I became interested in the process of growing food and how to go about growing healthy produce to consume, especially with my own hands, I felt like I had finally hit on what I was meant to study.” “My interest in healthy foods not only translates to my own health, but also Katherine C. Sozansky to the health of all consumers, as well producers, their families, their commu- University of Arkansas nity, and our environment. I feel like sustainable, organic production supports the health of all involved, while also following ecological practices that will support the land and soil ecology for many generations to come. I believe in teaching children to appreciate where their food comes from and all of the processes it takes to get their food from the farm to their fork, as well as to appreciate the hard work farmers and horticulturalists put into nurturing and cultivating the world’s food.” “One of the basic tenants of humanity is that we all have to eat, and the science behind feeding ourselves and feeding the land is what interests me most, and is what I plan to pursue through graduate school after I complete my undergraduate degree.”

Aaron Jantzi Yoder, currently an undergraduate student in horticulture at Kansas State University, admits “This is not a decision I might have foreseen five or so years ago, but I am certainly content with my decision at the present.” He adds. “I have always been fascinated by the diversity of plant life that ex- ists in our natural (and artificial) environments. The shapes, colors, and smells that plants provide are certainly aesthetically pleasing to our senses; however, my interest lies more in the function and use of these organisms. To speak and understand the science [of horticulture], one needs to first understand a plant. There is no better way to do this than to get your hands dirty, by experiencing plants in the physical sense. This is why I feel horticulture is such a good fit for me.” Aaron Jantzi Yoder “It is likely that I will pursue a myriad of adventures once I graduate, but one Kansas State University goal is to establish a fruit and vegetable production operation. I am particularly interested in small-scale production and the technologies and techniques that make small-scale production profitable. Horticultural research is also attrac- tive to me. I recognize that most of our botanical knowledge is a product of the innovation of horticulture. Where would plant science be if the greenhouse had not been developed? Would we really understand plants as much if our consumptive interests were absent? Blending horticultural management practices with ecological principles is an area of research that I find particularly interesting and would consider for graduate study. Areas such as integrated pest management and soil fertility are a couple specific examples of such fields of interest. will not pretend to act like I know precisely what I want to do when I graduate. In all honesty, I don’t know. I am certain that horticulture has been and will continue to be a primary interest of mine throughout my life.” Aaron Yoder is an ASHS Undergraduate Student Member.

According to Jacob who had something to say about horticulture and the state of Kingsley Shaw in his Presidential Address in 1938, captured affairs during their careers. The diversity of subjects and length forever in print by the noted ASHS Poet Laureate and historian of the addresses certainly warrant a scientific study in itself. In Dr. Jules Janick in his tome, Presidential Addresses 1903–2003, my address I will tease out some of their nuggets of wisdom that he stated “The first printed copy of our By-Laws requires that I believe speak to the issues that we horticulturists face today. It the president shall deliver an address at each regular meeting will be done with a seamless blend of humor, entertainment and and this is one section that has never been amended”.
