Table 1, printed p. 83, reports adjusted and unadjusted cold-injury ratings and trunk circumference for named rootstocks under Valencia orange tops. The 10-year-old planting was at Weirsdale, Florida; injury followed winter 1957–58 freezes and ratings were made June 18, 1958. The study-specific ratings are comparative rootstock results, not traits of the rootstock variety as a scion or a temperature threshold.
