Effect of Chlorocholine Chloride on Photosynthesis, Soluble Sugar and Terpene Trilactones of Ginkgo Biloba
The terpene trilactone content determines the quality characteristics of Ginkgo biloba extract. One of the means to increase terpene trilactones content is the use of plant growth regulators. The objective of this article is to study the effect of chlorocholine chloride (CCC), an antigibberellin growth retardant, on photosynthesis, photosynthetic pigment, soluble sugar and terpene trilactone content in ginkgo leaves. The ginkgo seedlings were grown in the greenhouse conditions with foliar applications off) (control), 0.5, 1.0 and 2.0 g r CCC. Results showed that 0.5, 1.0 and 2.0 g I1 CCC treatments significantly increased net photosynthetic rate, stomatal conductance, intercellular CO2 concentration, transpiration rate, and the contents of chlorophyll, carotenoids and soluble sugar in ginkgo leaves. The contents ofGA, GB, and BB of the leaves were markedly increased by 1.0 and 2.0 g T1 CCC treatments, whereas the content ofGC was not significantly affected by CCC treatment. However, the content of total terpene trilactones was significantly increased by 0.5, 1.0 and 2.0 g f1 CCC treatments and, was increased as the concentration of CCC increased. Foliar treatment with CCC therefore might be a useful means of improving pharmacological properties ofG. biloba leaves.
