Zeolites as additives for the rooting of Camellia japonica and Proteaceae Juss

Abstract

The term“zeolite” was created by Cronstedt (1756, for mineral which expel water when heated and hence seemto boil. They are very common and well known as fine crystals of hydrothermal genesis in geodes and fissures of eruptive rocks, or as microcrystalline masses of sedimentary origin. A natural zeolite is a framework alumina-silicate whose structure contains channel filled with water and exchangeable cations; ion exchange is possible at low temperature (100°C at most) and water is lost about 250°C and reversibly re-adsorbed at room temperature. In this test carried out at the CREA-OF (Pescia-PT) experimental greenhouses, the possibility of using chabazitic-zeolites mixed with the substrate to increase the rooting of ornamental crops such as Camellia and Leucospermum was evaluated. The results of the experiment showed a higher percentage of rooting of the cuttings placed in chabazite, compared to those in vermiculite, with a significantly increased level of microrrization.
