Abstracts |
A glasshouse study was carried out during 2002-2003 to evaluate the efficacy of different arbuscular mycorrhizal fungi strains for their utility as bio-hardening agent(s) for tissue culture derived grape (Vitis vinifera L.) plantlets at IARI, New Delhi. All the strains were found to significantly enhance the ex vitro survival of micropropagated plantlets over control. Growth parameters like plant height, root length, shoot and root dry weights, leaf number, leaf area and physiological parameters such as relative water content and photosynthetic rate registered significantly higher values in inoculated plantlets than the control. Furthermore, the nutritional status of the mycorrhizal plantlets was also found to be improved. The different arbuscular mycorrhizal fungi species tried were Acaulospora laevis, A. scrobiculata, Entrophospora colombiana, Gigaspora gigantea, Glomus manihotis, Scutellospora heterogama and a mixed arbuscular mycorrhizal fungi inocula. Acaulospora laevis followed by mixed inocula were found to be majority responsive as they affected most of the parameters and also resulted in maximum hardening success of tissue cultured plantlets. |
