摘要：Mountain pepper (Litsea cubeba (Lour.) Persoon) is an important oil plant used as an ingredient in edible oil, cooking condiments, cosmetics, pesticides, and potential biofuels. Zinc and boron are essential micronutrients for plant growth. However, the effects of zinc and boron on the yield, yield component, oil content, and citral content in L. cubeba have not been determined. This study was conducted to evaluate the efficacy of the foliar application of zinc, boron, and multiple micronutrients (zinc + boron) on the yield, yield component, oil content, and citral content of three varieties (Fuyang 1 (FY1), Jianou 2 (JO2), and Jianou 3 (JO3)) of L. cubeba. Zinc sulfate (0.25%), boric acid (0.25%), and zinc sulfate (0.25%) + boric acid (0.25%) were sprayed on selected trees at five different times at full bloom and 28 days before harvest, once every seven days. The results indicated that Zn had a negative effect on the yield, yield component, oil content, and citral content of the FY1, JO2, and JO3 varieties compared to the untreated trees. B had positive effects on the yield, yield component, oil content, and citral content of the JO2 and JO3 varieties but not on those of the FY1 variety when compared to the untreated trees. The highest levels of yield, yield component, oil content, and citral content for all three varieties were obtained with the combined application of zinc sulfate + boric acid. Hence, the foliar application of multiple micronutrients (zinc + boron) is an effective method to improve the yield, oil content, and citral content in L. cubeba. In addition, the 100-fruit weight (HFW) was positively correlated with the yield, oil content, and citral content and could be used as a tool to select new cultivars with high yield, high oil content, and high citral content under zinc sulfate, boric acid, and zinc sulfate + boric acid applications in L. cubeba.
