Management practices effects on Zanthoxylum planispinum ‘dintanensis’ fruit quality

Abstract

AbstractIn this work, field control experiments were conducted to clarify the effects of three management practices (dwarf and close planting + no sprinkling irrigation (A1), dwarf and close planting + sprinkling irrigation (A2), and natural growth (CK) on the quality of pericarp of Zanthoxylum planispinum ‘dintanensis’ in a plantation setting in a rocky desertification area of Central Guizhou Province. The results showed that the ash concentration of A2 was the highest (6.70% ± 0.42%), yet there was no significant difference from A1 (6.60% ± 0.14%) and CK (6.65% ± 0.64%), and methionine and cystine were not detected (detection limits were 13.90 and 43.60 mg kg–1, respectively). A2 management could significantly promote the concentration of amino acids (P < .05); vitamin C was not detected (detection limit was 0.20 mg kg–1), vitamin E ranked as A2 > A1 > CK, and β‐carotene ranked as A1 > A2 > CK. There were significant differences among management treatments; A1, A2, and CK had no significant effect on trace elements. In conclusion, dwarf and close planting + sprinkling irrigation is an ideal management practice improving the quality of dintanensis.
