- Abstract
The present study clarified the forest‐age associated change in the pericarp quality of Zanthoxylum planispinum 'dintanensis' (ZPD) and aimed to provide a theoretical foundation for formulating management strategies. The studied forest age groups consisted of 5‐to‐7‐, 10‐to‐12‐, 20‐to‐22‐, and 28‐to‐32‐yr‐old ZPD plants growing in rocky desertified areas of karst dry‐hot valleys in Guizhou, China. By measuring the pericarp quality indices of the plants present in the stands, the changes in pericarp quality were determined. The quality traits were optimal when the forest age was 28–32 yr, and the quality did not degrade with increased forest age. The sensitivity levels of ash contents and vitamins to the forest age were weak, whereas the levels of amino acids and trace elements were more affected by forest age. The latter two compounds were, therefore, more suitable for quality grading. The comprehensive quality index of the 28‐to‐32‐yr‐old plant group was the highest, followed by the 10‐to‐12‐yr‐old, 5‐to‐7‐, and 20‐to‐22‐yr‐old plants.
