Microbial Characterisation and Preparation of Inoculum for in vitro Mycorrhization of Strawberry in Autotrophic Culture
Abstract
Strategies to control losses in vitro due to microbial contaminants (vitropaths [1]) have been the subject of extensive research (see Leifert and Woodward, this volume). Significant additional losses, however, may also occur at microplant establishment (Williamson et al., this volume). Polygenic disease resistance develops in seedlings as the seedling develops and it is recognised that seedlings are vulnerable to pathogens if growth is checked due to adverse environmental conditions [2]. Microplants, especially if vitrified (‘hyperhydrated’), may undergo a growth check at establishment [3]. Hardening of plants in vitro (‘in vitro weaning’) has been shown to improve plant establishment and subsequent growth [4] and should assist in reducing losses due to damping-off.
