Induction of anthocyanins accumulation by methyl jasmonate in shoots of Crassula multicava Lam.

In Crassula multicava Lam. anthocyanins are formed naturally mostly in the stem near nodes and only traces in other parts of internodes. Methyl jasmonate (JA-Me) applied in lanolin paste at concentrations of 0.05, 0.1, 0.5 and 1.0% on the middle part of internodes greatly stimulated anthocyanins accumulation in the internodes and in the nodes of Crassula multicava. The stimulatory effect was higher in younger tissues of the Crassula multicava stem than in older ones, and depends on the used concentration of JA-Me. The possible role of jasmonates on anthocyanins formation in Crassula multicava is discussed.
