The fruit on the bottom came from a healthy tree.Bill Castle, an emeritus professor of horticulture at the University of Florida's Citrus Research and Education Center in Lake Alfred, recently led an informal survey that asked growers about their observations of huanglongbing, or HLB, and commercial citrus scion varieties.
He divided the state into traditional production regions: North Ridge, Central Ridge, South Ridge, Indian River District, Peace River Valley and Gulf Coast.
The survey was simple and contained one question: Do you agree or disagree with the list and order of scion varieties presented regarding the incidence of HLB?
Castle then invited respondents to change the order of common fruit fruit and juice varieties.
In addition, he asked for any comments about their observations on rootstocks.
