  • Slow growth storage refers to the techniques enabling the maintenance in vitro of shoot cultures in aseptic conditions by reducing markedly the frequency of periodic subculturing (from few months to one year or more) and the consequent risks of contamination, without affecting regrowth potential of shoots. The most used approach couples the storage of shoot cultures at low temperature (generally, 4 °C) with dark or low-light conditions. However, other factors (such as the medium formulation and the characteristics of containers) have important effects on the time of conservation. As for fruit species, the present study focused the attention on slow growth storage (at 4 °C and in the dark) of shoot cultures from three fruit rootstocks (GF677, Gisela5 and Mirabolano 29C) and the kiwifruit (cv. Hayward). Different sucrose concentrations (30, 45 and 60 g/L) and a sucrose/mannitol combination (30 and 15 g/L, respectively) in the conservation medium were tested, with the aim to improve the quality of the stored plant material and to prolong the conservation time. Kiwifruit, Mirabolano 29C and Gisela 5 greatly benefited when the sucrose concentration in the conservation medium was increased to 45 or 60 g/L, providing the conditions for a 18-month preservation of shoot cultures which maintained a good quality and the potential of recovering fastly the proliferation activity when moved back to standard culture conditions. GF677 shoot cultures could be preserved up to 21 months, with no marked differences among the 3 sucrose concentrations in terms of shoot quality. Mannitol, used in combination with sucrose, had detrimental effects on the conservation of GF677 and Mirabolano 29C shoot cultures. As for ornamental species, a study on slow growth storage of shoot cultures of Ranunculus and Anthurium is currently in progress, with promising preliminary results as for the possibility of in vitro conservation for at least 6 months.
