Ginkgo Leaf

Prior to Ginkgo leaf harvest, we implemented four exogenous applications of salicylic acid (SA: 50, 80, and 100 mg·L−1) or methyl jasmonate (MJ: 20, 40, and 80 mg·L−1) as leaf spray to investigate their effect on flavonoids content and related enzyme activity. Compared with the control, a significant increase of 12% and 26% in flavonoid content was observed 7 days after the first application of 100 mg·L−1 SA and 20 mg·L−1 MJ, respectively; both were determined to be the best treatments. Operationally, administering either elicitor (SA or MJ) 1 week prior to leaf harvest is deemed to be the most practical and economic option. Additionally, enzymes activity involved in flavonoid metabolism (phenylalanine ammonia-lyase, cinnamate 4-hydroxylase, and 4-coumarate:coenzyme A ligase) and antioxidants (peroxidase, superoxide dismutase, and catalase) significantly increased in most SA and MJ treatments. The results strongly support Ginkgo leaf response to SA- or MJ-induced stress through increased nonenzymatic antioxidant compounds (flavonoids) and activity of antioxidant enzymes.

The evergreen Ligustrum lucidum (glossy privet) suffers from freezing injury in northern China, where there are short growing seasons and early fall frost events. To investigate the influence of exogenous salicylic acid (SA) application on the natural cold acclimation of glossy privet, physiological and biochemical changes in glossy privet seedlings subjected to SA treatments at four concentrations (0, 150, 250, and 350 mg·L−1) were evaluated from Sept. to Dec. 2016. The optimum application concentrations were between 250 and 350 mg·L−1, which led to better freezing tolerance during natural cold acclimation. The improved freezing tolerance under exogenous SA application was associated with the accumulation of chlorophyll, proline, soluble protein, and soluble sugar, and the regulations of gibberellic acid (GA) and abscisic acid (ABA). Salicylic acid treatments started a cascade of steps for advancing the cold acclimation process of glossy privet. We suggest that exogenous SA application may be used on glossy privet grown in northern China.
