Inoculation of microshoots of Pieris floribunda (Pursh ex Sims) Benth. and Hook. (mountain andromeda) with isolates of Hymenoscyphus ericae (Read) Korf and Kernan ericoid mycorrhizal fungi stimulated growth during 1 month in vitro. However, no benefits were apparent after 3 months in a greenhouse. Acclimatization of plantlets of P. floribunda to greenhouse conditions following in vitro inoculation improved survival (42% vs. 16% for controls). The protocol reported herein is similar to procedures utilized currently for micropropagation of various ericaceous species and has potential to improve plantlet survival during acclimatization.

Cranberry and other members of the Ericaceae commonly form ericoid mycorrhizal (ERM) associations with fungi [e.g., Rhizoscyphus ericae (D.J. Read) W.Y. Zhuang and Korf [syn. Hymenoscyphus ericae (D.J. Read) Korf and Kernan] ( Allen et al

mycorrhizal fungi in a saline environment may be a result of differences in the timing and level of salinity, salinity source (e.g., salts of Na or Ca), crop species, and growing environment. Hajbagheri and Enteshari (2011) found that AMF increased root
