“…Pisolithus tinctorius used in the present study has an ability to produce considerable amounts of IAA in vitro (Niemi et al, 2000;Niemi et al, 2002b) and exogenous auxin, indole-3-butyric acid (IBA), has enhanced the ability of the fungus to form mycorrhizas in Scots pine roots (Niemi et al, 2002b). However, adventitious root formation is also under control of exogenous auxin and Fe-LS has been reported to act synergistically with auxins in adventitious root induction in vitro (Kevers et al, 1999;Van der Krieken et al, 1997). Kevers et al (1999) observed the highest rooting frequency in hybrid aspen (Populus tremula L. x P. tremuloides L.) and holly (Ilex basiflava) shoots when shoots were treated with auxin before the transfer onto Fe-LS containing medium.…”

“…However, similar characteristics to soil organic material make LS a potential compound to be used in forestry. LS has been shown to increase availability of fertilizer nitrogen (Meier et al, 1993) and phosphorous (Hao et al, 2000) in soil, and furthermore, LS chelates, such as Fe-LS and Ca-LS have enhanced auxin action in adventitious rooting of vegetatively propagated woody plants in vitro (Kevers et al, 1999;Van der Krieken et al, 1997). Van der Krieken et al (1997) suggested that LS released due to cell wall breakdown acts as an elicitor increasing sensitivity of plant tissues to auxin.…”

Lignosulfonate promotes the interaction between Scots pine and an ectomycorrhizal fungus Pisolithus tinctorius in vitro

2005

Lignosulfonate (LS) is a lignin-based polymer obtained as a by-product from paper industry, which may have potential as an amendment with macronutrients. We studied effects of LS on the interaction between Scots pine (Pinus sylvestris L.) seedlings and hypocotyl cuttings and the ectomycorrhizal (ECM) fungus Pisolithus tinctorius (Pers.) Coker and Couch. The experiments were performed in vitro on the MMN agar medium containing Fe-LS chelate at the concentrations of 0, 5, 10 and 25 mg/L. Inoculation with P. tinctorius increased root growth of the seedlings. Fe-LS enhanced P. tinctorius induced formation of lateral roots and had a dose-dependent positive effect on the establishment of mycorrhizas on the seedlings. The growth of the fungal mycelium was improved by Fe-LS, which might cause faster and more intensive contact with the roots and, thus, better root growth and mycorrhiza formation. P. tinctorius enhanced also adventitious root formation and subsequent root growth of the hypocotyl cuttings but without any synergistic effect with Fe-LS. Our study with P. tinctorius and Scots pine in vitro indicates that a low-cost by-product Fe-LS, obtained from paper industry, may be a potential tool to improve the efficiency of fungal inoculations, thus, facilitating the early interaction between an ECM fungus and host seedling.Abbreviations: ECM -ectomycorrhiza l; IAA -inodole-3-acetic acid; LS -lignosulfonate

“…Wounding might have also helped in the stimulation of cell division and promotion of root primordia by better utilising the auxins and other root promoting substances (Malla Reddy, 1991). Wounding-related compounds play an important role in rooting ( Van der Krieken et al, 1997). The use of auxin alone did not improve rooting significantly in prepared cuttings including the entire length of the proleptic shoot.…”

This study analyses the influence of auxin and wounding on the rooting of stem cuttings of Protea ‘Susara’ (P. magnifica × P. susannae) prepared from proleptic shoots. Two assays were carried out. Terminal cuttings, 10-15 cm long, treated with 4000 mg L–1 of indole-3-butyric acid (IBA) and wounded or not were used in the first experiment. The combination of wounding + IBA did not significantly improved rooting compared with the use of IBA alone (70% and 53.3% of transplantable cuttings, respectively). Three levels of IBA (0, 2,000 and 4,000 mg L–1 ) , with or without wounding, and cuttings including the total length of the shoot were used in the second assay. At the end of the trial (24 weeks), wounded cuttings treated with 2,000 mg L–1 or 4,000 mg L–1 of IBA yielded 90% of transplantable cuttings. The combination of wounding + IBA significantly favoured rooting in comparison with the use of IBA or wounding alone.

“…This might be because cutting (wounding) stimulates the production of wounding related compounds (WRCs) and ethylene biosynthesis at the cut surface (De Klerk, 2002a;De Klerk et al, 1999a and b). It has been suggested that WRCs and related compounds play an important role in rooting (Van der Krieken et al, 1997). De Klerk et al, (1999b) studied the mode of action of WRCs.…”

“…In addition to above mentioned phytohormones, other endogenous factors have also been identified to play a role in AR formation, such as calcium (Ca 2+ ) (Bellamine et al, 1998), sugar (Li andJia, 2013), phenolics (Rout, 2006), polyamines (Nag et al, 2001), nitric oxide (NO) (Pagnussat et al, 2002(Pagnussat et al, , 2003(Pagnussat et al, , 2004, carbon monoxide (Xu et al, 2006), cyclic guanosine monophosphate (cGMP), mitogen-activated protein kinase (MAPKs) (Pagnussat et al, 2003(Pagnussat et al, , 2004, wounding related compounds (Van der Krieken et al, 1997), and peroxidase (Syros et al, 2004). Some of these molecules may function in signaling and mediate auxin-induced adventitious rooting and auxinresponse gene expression.…”
