↵1 Treatment rate based on the species-specific category on the Cambistat® label is indicated as “full rate”; the category below full rate is indicated as “1CL”; 2 categories below full rate is indicated as “2CL”; and non-treated were controls.
↵2 Replicates that survived the duration of the experiment were used to quantify all response variables except for average total root length.
↵3 Rates were based on stem caliper of plant. The amount of water applied per application was 11 mL of water/mL of Cambistat® for all treatments.
↵4 Dosage based on the amount of grams of paclobutrazol administered based on stem caliper of plant.
