“…The nutrition condition of the soil in this study was relatively poor compared to commercial cultivation conditions, as no additional fertilizer was applied at all. It has been reported that the application timing of PGPR affects yield (Vestberg et al, 2004;Palencia et al, 2015). This is in line with the results of this study that the application during flower induction treatment can affect yield and numbers of fruits in the first fruit truss in 'Hokowase' (Table 5).…”

Plant growth promoting rhizobacteria (PGPR) is applied as biofertilizer to expect better production potential on commercial crops while keeping sustainability, but their function is dependent on the combination of PGPR and target crops. It has been reported that the application of PGPR in the soil resulted in the increment of strawberry yield, but other reports argue that PGPR has no effect on the yield potential. In addition, it is not clear whether the application timing of PGPR affects in a forcing cultivation system which usually requires transplanting. In this study, responses of diploid wild strawberry (Fragaria vesca) and garden strawberry (F. ananassa Duch.) varieties to PGPR application were examined. Application of PGPR, Bacillus cereus KI-2, during the flower induction increased the total yield and number of fruits in F. vesca 'Hawaii-4', and in garden strawberry 'Hoko-wase'. The application resulted in earlier flowering in 'Hoko-wase' while no difference was observed in 'Tochi-otome'. Sucrose content was also altered in cultivar dependent manner so that it was increased in 'Hawaii-4', while it was decreased in 'Tochi-otome'. These results indicate that PGPR has a potential to improve the yield factors while keeping the quality of the fruits, but the effect is cultivar dependent.

“…Although several studies have been performed in order to improve the in vitro propagation technique, difficulties are still being encountered in achieving satisfactory plant acclimatization. Microplants maintained in vitro under aseptic conditions are susceptible to biotic and abiotic stresses when transferred to a post-vitro environment (Vestberg et al 2004). As a result, significant losses can occur at acclimatization due to the vulnerable physiological status of microplants (Grunewaldt-Stoecker 1997).…”

The effect of Azospirillum brasilense Sp245 on the micropropagation of three fruit rootstocks: Mr.S 2/5 plum (Prunus cerasifera )P. spinosa), GF 677 hybrid (Prunus persica )P. amigdalus), and MM 106 apple (Northen Spy )M1) was assessed. Rooted shoots were treated with 3 )10 7 of Sp245 cells during transplantation from in vitro cultures to the acclimatization phase. After 60 days, growth parameters were positively affected by Sp245 inoculum. In the case of Mr.S 2/5, an increase in rootstock stem length and node number by 37% and 42%, respectively, compared to the control was noted. In the case of GF 677, the bacterial inoculum increased stem length and node number by up to the 75% and 65%, respectively, compared to the control. The inoculum did not exert on MM 106 for both parameters suggesting that the effects of Sp245 could depend on a specific clonemicrobe association. In all cases, however, a higher vigor, consistent with a wider leaf area, was present in the inoculated plantlets demonstrating that the use of Azospirillum can significantly contribute to optimize plant performance during the phase of adaptation of plants to post-vitrum conditions.

“…Taken together, these recent findings The effects of co-inoculation on plants depend on the particular combinations used (Andrade et al 1998;Barea et al 1998). The interactions have ranged from the very compatible (producing positive effects), the less compatible (producing neutral effects), to the incompatible (producing detrimental effects), or demonstrated better results from single inoculations rather than dual inoculations (Vestberg et al 2004). Based on our study, the combination of AMF and mycorrhizal endosymbiotic bacteria B. subtilis B10 produced positive effects on the height of oil palm seedlings but might be less compatible or neutral on root dry weight.…”

Oil palm (Elaeis guinnensis Jacq) is one of the highest yielding plants in oil producing crops and the most important plantation and commercial crop in Indonesia. However, some fungal diseases have reduced the annual production of oil palm in South East Asia (Idris et al. 2003). Fungal pathogen Ganoderma boninense, the causal agents of basal stem rot (BSR) in oil palm, can severely attack the plant leading toThe effects of mycorrhizal endosymbiotic bacteria Bacillus subtilis B10 and composite of arbuscular mycorrhizal fungal spores in green house experiment were examined in order to evaluate their effectiveness and compatibility with oil palm seedlings in the presence of a fungal pathogen Ganoderma boninense, the most serious pathogen in oil palm (Elaeis guineensis Jacq) in Indonesia. A three factors experiment were conducted, with mycorrhizal inoculation (M0 and M1), bacterial B. subtilis B10 inoculation (B0 and B1), and G. boninense inoculation (G0 and G1) as the first, second, and third factors, respectively. The results showed that disease severity index, plant height, root dry-weight, and phosphorus uptake were affected by co-inoculation of mycorrhizal endosymbiotic bacteria B. subtilis B10 and composite of arbuscular mycorrhizal fungi. Coinoculation of mycorrhizal endosymbiotic bacteria B. subtilis B10 and arbuscular mycorrhizal fungi did not only reduce the percentage of basal stem rot incidence, but also significantly increased plant height and phosphorus uptake by oil palm seedlings. Our results suggest that in oil palm seedlings mycorrhizal endosymbiotic bacteria B. subtilis B10 worked synergistically with arbuscular mycorrhizal fungi in increasing plant adaptation toward biotic stress of pathogen G. boninese and could be promising biocontrol agents.Key words: arbuscular mycorrhizal fungi, Bacillus subtilis B10, biotic stress, Ganoderma boninense, mycorrhizal endosymbiotic bacteria, oil palm seedlings Patogen Ganoderma boninense Pat penyebab penyakit busuk pangkal batang merupakan patogen paling mematikan pada tanaman kelapa sawit (Elaeis guineensis Jacq).
