Blueberry Genotypes: Stomatal Diversity, Light Response
Stomata are pores on the leaf surface that control gas exchange between leaves and the atmosphere. Stomata differ in shape, size, and number among and within plant species. Stomata morphology has physiological consequences for some plant species.
The research examines multiple blueberry genotypes grown in Florida, Alabama, Wisconsin and Mexico. The study demonstrates that stomatal traits play a crucial role in determining how rapidly blueberry plants respond to changing irradiance levels, influencing overall plant performance and productivity.
According to the author, “Finding that some blueberry varieties have faster stomata than others is promising because, in other crops, varieties with fast stomata have higher water use efficiency”.
This research adds to the growing body of knowledge linking on plant physiological
responses and their role in agricultural sustainability. The study’s insights may help
farmers and breeders select blueberry varieties with optimal stomatal traits, leading to
enhanced crop performance in diverse environmental conditions.
Dr. Nunez is an Assistant Professor in the Horticultural Sciences Department, Institute of Food and Agricultural Sciences, at the University of Florida, Gainesville. His research explores how abiotic stimuli and cultural practices impact berry crop quality, productivity, and resilience. Sarah Benevenute, a doctoral student in Dr. Nunez’s laboratory is the first author of the study. Graduate student Paul Adunola also contributed to this work.

Established in 1903, the American Society for Horticultural Science is recognized around the world as one of the most respected and influential professional societies for horticultural scientists. ASHS is committed to promoting and encouraging national and international interest in scientific research and education in all branches of horticulture.
Comprised of thousands of members worldwide, ASHS represents a broad cross-section of the horticultural community-scientists, educators, students, landscape and turf managers, government, extension agents and industry professionals. ASHS members focus on practices and problems in horticulture: breeding, propagation, production and management, harvesting, handling and storage, processing, marketing and use of horticultural plants and products.
