Abstract Not Available – First paragraph follows:
In attempts to increase the cold tolerance of young citrus trees, chemicals (including a growth retardant, three anti-transpirants and two plastics) were applied to grapefruit nursery trees that were then planted in the field. The results showed a slight but not commercially important increase in frost tolerance.
