Effects of nanosponges including new anti-ethylene compounds on post-harvest longevity of cut flowers and of nanosponges including phytohormons on in vitro regeneration of ornamental species

Nanosponges can favour the gradual release of molecules in an extended time, increasing the bioavailability and the action of preservative substances and phytoregulators, reducing the usually adopted high concentrations. In floriculture, it has been recently experimented and proposed for delivering anti-ethylene compounds in order to improve the vase-life of cut flowers. Moreover, nanosponge/growth regulators complexes could be used to improve in vitro propagation and rooting of ornamental species.
