and petioles from each tree were collected and submitted for nutrient analysis (Waypoint Analytical Laboratory, Mulberry, FL). Fruit physical, compositional, and nutrient analysis. Three fruit from each color treatment were harvested within ≈3
analysis. Substrate solutions were immediately measured for pH and EC then frozen until a nutrient analysis was performed. At the time of nutrient analysis, samples were thawed, filtered through GF/F binder-free borosilicate glass fiber filter paper
the tree and placed in the cuvette at 25 °C with 350 μL·L −1 CO 2 and irradiance at 1000 μmol·m −2 ·s −1 PPF ( PPF ). Assimilation was recorded once carbon exchange stabilized (≈4 min). Tissue nutrient analysis. A random sample of dried
soils used for planting palms in street medians, highway rights-of-way, and many new commercial and residential landscapes in Florida. Physical and nutrient analysis results of four replicate samples of each of these soils was determined by A & L
recorded for each of those samples. The five samples from each crop were then combined into one sample per crop and sent to Quality Analytical Laboratories (Panama City, FL) for a complete nutrient analysis using inductively coupled plasma atomic emission
the optimum concentration, whereas the N and Fe concentration were lower than the critical soil test values ( Obreza and Morgan, 2008 ) ( Supplemental Table 1 ). Leaf nutrient analysis of 10 elements (N, P, K, Ca, Mg, Fe, Mn, Cu, Zn, and B) showed that
the root ball and dried for 48 h at 66 °C) at both planting dates. From these nonplanted shrubs of each species, leaf tissue samples were taken from the most recently matured leaves for tissue nutrient analysis (Auburn University Soil Testing
, and shoot and root tissue samples for nutrient analysis. Rooting stage for each treatment was determined using a rooting scale defined by Dole and Gibson (2006) . Tissue N concentration was measured as total Kjeldahl N where protein was converted to
extra-small size category of less than 40-mm diameter) were regarded as marketable yield ( Maboko et al., 2011 ). Leaf nutrient analysis. The fourth leaf from the growing point of four plants per replicate per treatment was selected to determine the leaf
