“…It is presumed that during the first weeks (before root initiation), the plantlets developed on their own nutrient reserves (starch accumulated in the corm) (Aragón et al 2006). In addition, competition for carbon may have occurred between the plantlets and the AMF, resulting in a lack of stimulation of the mycorrhized plantlets in the MSR+AMF treatment relative to the controls (Graham et al 1996;Balla et al 1998;Smith and Smith 2011).…”

Micropropagated banana plantlets represent a good planting material to establish new growing areas or replace old plantations. The plantlets are devoid of pathogens but also of beneficial root inhabitants (e.g., endophytes and arbuscular mycorrhizal fungi [AMF]) that may help plants withstand stresses. Mycorrhization of banana is usually conducted at the hardening/post-hardening phases. Only a few studies have reported their application in vitro, and none have investigated the subsequent impact on ex vitro acclimatization. Here, we report for the first time the effects of in vitro mycorrhization of banana plantlets on growth following transfer to soil. Banana plantlets were pre-mycorrhized under autotrophic conditions. During in vitro culture, heavy root colonization of the banana plantlets was observed. At 5 and 7 wk after transfer to a peatsand soil substrate, the root system remained highly colonized. The growth (pseudostem height) and biomass were significantly higher than those of control plants grown on media without AMF. The mean shoot dry weight of the premycorrhized plants at 5 wk after transplanting was 66.7 and 34.6% greater than those of non-mycorrhized plantlets grown on modified Strullu-Romand (MSR) and Murashige and Skoog (MS) media, respectively, and was also greater at week 7 (by 64.7 and 40%, respectively). In vitro mycorrhization under autotrophic culture conditions thus represents a promising tool for the pre-adaptation of micropropagated banana plantlets to ex vitro conditions.

“…Fortuna et al (1992) reported a two-week acclimation period for the micro-propagated and AMF inoculated plum rootstock in comparison to non AMF inoculated ones. The survival rate and growth of some micro-propagated trees has been reported (Balla et al 1998). For this process healthy shoot-tips of the GF 677 peach rootstocks are collected.…”

“…Beside these, several other parameters are also taken, such as the nutrient content, photosynthetic activity, carbonbalance studies, etc. A higher colonisation is obtained by using AM fungal strains originating from the same soil or sometimes from the rhizosphere of the same hosts (Balla et al 1998;Biró et al 1998). …”
