“…A strain of Azospirillum brasilense enhanced rooting and acclimatization of Prunus cerasifera (Russo et al 2008). According to Thomas et al (2010), bacterization of explants in vitro can be unsuccessful due to lack of colonization or culture overgrowth. In many cases, better results in plantlet survival and ____________________________________________________________________________________________________________________ growth can be obtained when bioinoculants are used to amend the soil or during an in vitro rooting in the perlite, as in our experiment.…”

The strains of bacteria Paenibacillus glucanolyticus, Curtobacterium pusillum and Methylobacterium extorquens were isolated as non-deleterious contaminations from hosta or raspberry tissue cultures. Microshoots of chrysanthemum, gerbera, hosta and rose were inoculated with these bacteria and their influence on shoot multiplication and rooting was evaluated. None of the investigated bacteria caused symptoms of hypersensitivity or vitropathy on the shoot explants at rooting and shoots multiplication. C. pusillum stimulated axillary shoot formation in all studied plant genotypes. Length and number of rose roots and their length were higher but number of roots and their length in chrysanthemum were lower in inoculated than in controls. The number and the length of shoots and roots in gerbera and hosta and the number of shoots in chrysanthemum inoculated with M. extorquens were higher but shoot length of chrysanthemum and rose, and root length of rose were lower as compared with controls. P. glucanolyticus influenced higher number and length of chrysanthemum shoots and root length of chrysanthemum and gerbera than noninoculated control but the number of gerbera and hosta roots was lower and root length of rose was as low as 0.2 cm. All assessed bacteria were able to assimilate atmospheric nitrogen and M. extorquens and P. glucanolyticus were able to produce IAA.

“…Other studies in the literature were conducted over up to 90 days (Thomas et al 2010). Despite the fact that this experiment did not observe variations between the inoculated treatments and the non-inoculated control, it is not possible to discard the hypothesis that inoculation with rhizobia can be efficient.…”

“…In other studies, the positive effect of inoculation with plant-growth promoting bacteria has already been established. The acclimatization experiment of Camellia sinensis inoculated with Azospirillum showed changes in the shoot length and fresh weight after a period of 90 days (Thomas et al 2010). (Oliveira et al 2010) observed an increase in the shoot and fresh-root weight of Zingiber spectabile inoculated with Bacillus pumillus after three months.…”

In vitro rooting and the acclimatization of micropropagated rootstocks of apple trees is essential for plant development in the field. The aim of this work was to assess the use of rhizobia of Adesmia latifolia to promote rooting and acclimatization in micropropagated Marubakaido apple rootstock. An experiment involving in vitro rooting and acclimatization was performed with four strains of rhizobium and two controls, one with and the other without the addition of synthetic indoleacetic acid. The inoculated treatments involved the use of sterile inoculum and inoculum containing live rhizobia. The most significant effects on the rooting rate, primary-root length, number of roots, root length, fresh-shoot biomass, and fresh-root biomass were obtained by inoculation with strain EEL16010B and with synthetic indole acetic acid. However, there was no difference in the growth of apple explants in the acclimatization experiments. Strain EEL16010B can be used to induce in vitro rooting of the Marubakaido rootstock and can replace the use of synthetic indoleacetic acid in the rooting of this cultivar.

“…Acclimatization is one of the important processes in plant micro propagation before plantlets/planting materials are ready to be cultivated in the field (Pospóšilová et al, 1999;Hazarika, 2003;Thomas et al, 2010). The purpose of acclimatization process is to establish plant condition from in vitro to field condition (Robinson and Sáuco, 2009).…”

Acclimatization is one of the important processes in banana micro propagation before plantlets/planting materials are ready to be cultivated in the field. Trichoderma sp. are well known as plant promoter fungi that can promote plant growth and increase survival rate of plantlets. The study was arranged in a Completely Randomized Factorial Design with two factors and four replications. The first factors was covering type i.e. 1) individual covering and 2) mass covering. The second factor was the proportion of Trichoderma addition into manure, namely A) manure without the addition of Trichoderma sp. (control), B) Trichoderma sp. : manure = 1 : 400 (w/w), C) Trichoderma sp. : manure = 1 : 800 (w/w) and D) Trichoderma sp. : manure = 1 : 1,200 (w/w). The purpose of this study was to investigate the effect of Trichoderma sp. applications and covering types in the growth of banana plantlets cv. Barangan during the acclimatization process. The results showed that the best treatment to induce plantlet growth during the acclimatization process was the addition of Trichoderma sp.: manure with 1 : 400 (w/w) proportion and individual covering. The combination of Trichoderma sp. : manure with 1 : 400 (w/w) proportion and individual covering produced plant height and leaf length 8.5 cm and 4.4 cm, respectively, compared to the treatment without Trichoderma sp. addition that produced plantlets with 6.6 cm height and 3.4 cm leaf length. No significant interaction was shown between Trichoderma sp. proportions and covering types on leaf width, the number of leaves and root length parameters.
