“…Induced resistance responses to microbial inoculants are well documented in plants grown in vivo (Benhamou et al 1996;Hunt and Ryals 1996;Kloepper et al 1997). Moreover, induction of stress resistance in plant propagules produced in vitro prior to transplanting is the primary target of several research groups attempting utilization of microbial inoculants in micropropagation (Hooker et al 1995;Nowak et al 1995;Balla et al 1997;Lazarovits and Nowak 1997;Murphy et al 1997;Wilhelm et al 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.

“…Under in vitro conditions, root hairs either do not form or form in numbers insufficient for a normal supply of water and mineral components from soil solution. Therefore, for some species (mostly woody plants or legumes), a number of symbiological techniques have been utilized, including artificial mycorrhization (Estrada-Luna et al 2000) and combined treatment with vesicular arbuscular mycorrhizal fungi and Rhizobium (Balla et al 1997). López-Lima et al (2013) used the nematophagous fungus Paecilomyces sp.…”

Microclonal propagation in vitro is being actively used in the production of healthy planting material of food and ornamental plants. However, it needs further improvement to increase the growth rates of microclones in vitro and enhance regenerant survivability ex vitro. A promising approach to this end could be inoculating in vitro-micropropagated plants with plant growth-promoting rhizobacteria, specifically Azospirillum. However, the influence of Azospirillum inoculation on microclone behavior throughout the production process, including plant adaptation ex vitro and food crop productivity, has been underinvestigated. In this study, in vitrogrowing potato (Solanum tuberosum L.) microclones were inoculated with Azospirillum brasilense strain Sp245. The microclones were then grown on in soil in the greenhouse and field, with the experiment lasting for 120 days. Rootassociated bacteria were identified immunochemically, and the mitotic index of root meristematic cells was determined by a cytological method. The plant morphological parameters determined were shoot length, number of nodes per shoot, number of roots per plant, maximal root length, leaf area, percentage of surviving plants in the soil, and tuber yield and weight. Our results show that bacterial inoculation of potato microclones in vitro enhances plant adaptive capacity ex vitro and increases minituber yield. The percent survival index of field-grown inoculated plants was 1.5-fold greater than that of uninoculated plants. The overall tuber weight per plant was more than 30 % greater in the inoculated plants than it was in the control ones. For all cultivars on average, tuber yield per square meter increased by more than 45 % as a result of inoculation in vitro. This study is the first to report that Azospirillum inoculation of potato microclones not only improves the quality of planting material produced in vitro but also significantly increases minituber yield through enhancing plant adaptive capacity in the field.

-In Hungary black locust (Robinia pseudoacacia L.) is considered as an important exotic stand-forming tree species growing mostly under unfavourable ecological conditions for forest management. Due to climate change effects its importance is increasing in many other countries, too. As a result of a selection programme new black locust clones were tested in clone trials. Juvenile growth and the morphological as well as phenological traits of four micropropagated black locust clones were evaluated in central Hungary under dry site conditions. Significant differences (P<5%) were found for DBH and field survival rate values. At age of 7 the clone R.p. 'Bácska' ('KH 56A 2/5') appears to be especially promising for mass propagation. Tissue culture can be considered as a suitable tool for propagating superior individuals and offers new prospects for the rapid cloning of selected genotypes used for plantation forestry.Black locust (Robinia pseudoacacia L.) / clone trial / juvenile growth / micropropagation Kivonat -Mikroszaporított fehér akác (Robinia pseudoacacia L.) klónok fiatalkori növekedése és morfológiai jellemzői száraz termőhelyeken. Magyarországon a fehér akác (Robinia pseudoacacia L.) fontos állományalkotó egzóta fafaj, főként az erdőgazdálkodás számára kedvezőtlen termőhelyeken. A klímaváltozás hatásai miatt a fafaj jelentősége folyamatosan növekszik több más országban is. Egy szelekciós program eredményeként új akác klónokat állítottunk elő klónkísérletek létesítése céljából. Jelen tanulmányban négy mikroszaporítással előállított akác klónt értékeltünk fiatalkori növekedésük, továbbá morfológiai és fenológiai jellemzőik alapján Közép-Magyarországon száraz termőhelyi viszonyok között. Szignifikáns különbséget (P<5%) találtunk a mellmagassági átmérő és a megmaradási értékek tekintetében. 7 éves korban az R.p. 'Bácska' ('KH 56A 2/5') klón különösen ígéretesnek tűnik a tömegszaporításra. A szövettenyésztéses szaporítási eljárás megfelelő eszköznek tekinthető az ültetvényes fatermesztés területén kiváló minőségű egyedek klónos elszaporítására, új távlatokat nyújtva ezzel a kiválasztott genotípusok gyors klónozására.Fehér akác (Robinia pseudoacacia L.) / klónkísérlet / fiatalkori növekedés / mikroszaporítás
