Shoot-tip cryopreservation by droplet vitrification of Byrsonima intermedia A. Juss.: a woody tropical and medicinal plant species from Brazilian cerrado.

Abstract

Cryopreservation of plant species is poorly investigated in Brazil. The aim of this study was to cryopreserve Byrsonima intermedia shoot apical meristems through droplet vitrification. A culture medium for shoot-tips growth was established using the Woody Plant Medium supplemented with 2.22 uM 6-benzylaminopurine. Excised shoot-tips were subjected to pre-culture and/or post-culture treatments on Murashige and Skoog medium with 0.3 M sucrose for 24 h prior dehydration on PVS2 at 0°C for 15, 30 or 45 minutes prior to plunging in liquid nitrogen. The effect of 15 days of shoot pre-growth on a high osmotic medium (0.3 M sucrose or 0.21 M sorbitol + 0.09 M sucrose) prior to meristem excision and cryopreservation was also investigated. Pre-culturing shoot-tips on 0.3 M sucrose for 24 h prior to cryopreservation increased the regrowth level after thawing to 90%. Shoot-tips excised from shoots pre-grown on MS + 0.21 M sorbitol + 0.09 M sucrose for 15 days presented a satisfactory regrowth level (67%).
