“…Storey et al (1971) determined that 140 lb of ZnSO 4 per tree was required to alleviate zinc deficiency in calcareous Texas soils. In Arizona, neither band application of 75 lb/ac of Zn as ZnSO 4 nor 20 lb/ac as Zn‐EDTA consistently increased Zn uptake in mature ‘Wichita’ pecans growing in a calcareous soil (Nuñez‐Moreno et al, 2009).…”

“…Below the required inferior level, there is also inhibition of plant growth [6] [10], biochemical and physiological changes, as well as morphological and structural differences [11] due to physiological stress caused by dysfunctional metabolic functions on which Zn has an important role [8]. Within the functions that present alterations are carbohydrate, lipids and nucleic acids metabolism, protein synthesis and reproductive development such as pollen formation, structural and functional integrity of biomembranes, photosynthetic C metabolism and chlorophyll biosynthesis [4] [7] [12].…”

The purpose of this study was to analyze the effect of Zn nutritional status on the content of pigments, nonstructural carbohydrates, foliage proteins and amino acids of the pecan tree, as possible bioindicators of Zn deficiency. The experimental design was completely random with three Zn nutritional statuses: Normal, Intermediate and Deficient, being selected considering visual symptomatology. On all three nutritional statuses, the concentration of photosynthetic pigments was determined as well as of total soluble proteins and amino acids. Obtained results indicate that Zn deficient nutritional status was characterized by minimum photosynthetic pigment, protein concentrations, maximum amino acid and nonstructural carbohydrate concentrations. While the normal Zn nutritional status presented maximum photosynthetic pigments, proteins concentrations, minimum amino acids and carbohydrate concentrations. On the other hand, intermediate Zn nutritional status was characterized by a medium level between the other two Zn nutritional statuses. Finally, we stress the fact that pigments, proteins, amino acids and nonstructural carbohydrates may be good physiological indicators related to Zn nutritional status on pecan trees.
