Horticultural Sciences

"Florida's agricultural industry generates more than $103 billion in annual economic impact and employs more than 500,000 people. Florida's farmers produce nearly 300 commodities, and winter vegetables and citrus consistently lead the national rankings. To meet the needs of this diverse industry, research and extension programs in the areas of fruit and vegetable production, postharvest technology and weed science are delivered on a county, regional and statewide basis using a variety of methods including field days, intensive hands-on training, and distance learning. Excellence in programming facilitates the exchange of information and technology and contributes to the professional development of extension faculty and the agricultural clientele they serve."

Using Supplemental Lighting to Grow Hemp in Florida

HS1452/HS1452by J. Desaeger, J. Coburn, and S. AgeharaOctober 26th, 2022With the removal of hemp from the controlled substances list, hemp is now one of the emerging crops in Florida. There is limited information on how to grow this crop in Florida. Like hops, hemp is another recently introduced crop in the state, with one of the major yield-limiting factors of premature flowering induced by inadequate day length. This article provides guidelines for hemp growers in Florida on the use of supplemental lighting to control flowering and improve growth of hemp under Florida’s environmental conditions. Written by Johan Desaeger, Jacqueline Coburn, and Shinsuke Agehara, and published by the UF/IFAS Horticultural Sciences Department; 4 pp.Critical Issue: Agricultural and Food Systems

Improving Strawberry Varieties by Somaclonal Variation

HS1448/HS1448by Cheol-Min Yoo, Cheryl Dalid, Catalina Moyer, Vance Whitaker, and Seonghee LeeOctober 2nd, 2022Somaclonal variation is a breeding method utilizing natural genetic variation induced by a tissue culture process instead of by hybridization. This offers an alternative to mutation breeding for the introduction of new genetic variations in existing strawberry varieties. The main purpose of this new 5-page publication of the UF/IFAS Horticultural Sciences Department is to share the potential of this technique with plant breeders in the public and private industries. The secondary purpose is to educate the industry and the public on the scientific background of somaclonal variation.
