Congratulations to the Jones lab! Luckily, one of the lab members, Laura Chapin, had time to tell us in her own words about the experience and achievements of the lab at this year's ASHS, in New Orleans, LA. Read below...


The American Society for Horticultural Science (ASHS) is the leading professional society for horticultural scientists, educators, and industry professionals. With members from around the world, ASHS is dedicated to advancing all facets of horticultural research, education, and application, with the goal of improving crops, production systems, and the communities they serve. This year’s annual conference was held in New Orleans, Louisiana, where members of the Jones Lab traveled to both celebrate and share their research. 

Dr. Michelle Jones was elected as a Fellow of the American Society for Horticultural Science (ASHS), the Society’s highest honor, in recognition of her outstanding contributions to horticultural science. Election as a Fellow is reserved for members whose professional achievements enhance the prestige, influence, and reputation of ASHS. 

The conference was also a moment of recognition for Jones Lab graduate student Juan Quijia Pillajo, PhD candidate, who received the ASHS Graduate Student Scholars Award, honoring his exceptional accomplishments at the graduate level. 

Jones Lab members also shared their research at the conference: 

  • Juan Quijia Pillajo, PhD candidate, moderated a floriculture session and presented his research on phosphate-solubilizing bacteria.

    • Substrate pH and Inoculant Amendments Modulate Phosphate-Solubilizing Bacteria Efficacy in French Marigold: Impacts on Plant Health and Rhizosphere Microbiome.  

  • Alexandra Espinoza, PhD student, gave an oral presentation on the use of beneficial bacteria and a specialized substrate mix to reduce phosphorus leaching during greenhouse production of ornamental plants. 

    • Using Plant Growth Promoting Rhizobacteria to Enhance Plant Growth with the Ferrous Sulfate Bridge Method for Reducing Phosphorus Leaching. 

Alexandra Espinoza

  • Janhavi Maurya, pursuing her MS degree, presented a poster showcasing her research on digital phenotyping with 3D scanners to evaluate nutrient deficiencies in greenhouse crops.

    • Evaluation of Nitrogen, Phosphorus, and Potassium Deficiency in Ornamental Crop Species Using a Digital Phenotyping System.

  • Ashly Ramos, currently an MS student, presented a poster on the interaction of fertilizer rates and phosphorus doses with a commercial biostimulant product in greenhouse-grown ornamental plants. 

    • Fertilizer Rate and Phosphorus Dose Influence Growth Promotion and Phosphorus Absorption in Lalrise-Vita Treated Marigolds and Pansies.

  • Laura Chapin, a research associate, presented a poster on the influence of substrate pH and plant species on the rhizosphere microbiome, as well as an oral presentation on the effect of siderophore-producing bacteria on plants grown in iron-limiting conditions.

    • Influence of Peat-Based Substrate pH and Plant Species on Rhizosphere Bacterial Communities.

    • Siderophore Producing Bacteria Isolated From the Rhizosphere of Greenhouse Plants Enhance Plant Growth Under Iron-Limiting Conditions.
