Effect of Arbuscular Mycorrhizal Inoculations on Seedling Growth and Biomass Productivity of Two Bamboo Species

Abstract

A study was conducted to identify suitable arbuscular mycorrhizal (AM) fungi for inoculation of Bambusa bambos and Dendrocalamus strictus at nursery stage for increasing growth and productivity. Twelve AM species, isolated from bamboo and other common trees of Bundelkhand were used for inoculations. In B. bambos, total dry weight and phosphorus (P) uptake were significantly increased by all studied fungi and shoot length was increased by eight AM inoculants. Maximum mycorrhizal dependency (MD) was recorded for Acaulospora scrobiculata (44.2%), followed by Glomus cerebriforme (41.6%) and G. intraradix (41.0%). In D. strictus, all tested AM inoculants significantly increased shoot length, dry shoot weight and P uptake, except Glomus 1. Dry root weight was significantly increased by only two inoculants namely, G. cerebriforme and G. etunicatum. Total dry weight was significantly increased by eight AM fungi. Maximum MD was recorded for G. cerebriforme (62.9%), followed by G. diaphanum (55.0%) and G. etunicatum (51.3%). Thus, the results showed that utilization of effective AM fungi can enhance the productivity of bamboo in the region.

Soil depth: an overriding factor for distribution of arbuscular mycorrhizal fungi

“…The pre-dominant occurrence of Glomus species showed their remarkable adaptation to the drastic condition of our region i.e. Bundelkhand, Central India (Soni and Vyas, 2007;Jha et al 2011). Results also suggested that A. scrobiculata, Acaulospora sp 1, G. aggregatum, Sep.…”

“…These are recognized as an important component of soil ecosystem (Oehl et al, 2004 and2005;Shukla et al, 2012b). AMF can improve plant growth under low fertility conditions, improve water balance of the plants and help plants to establish in new areas (Jha et al, 2011;Shukla et al, 2012c). Distribution of AMF is a result of contemporary ecological processes (Shukla et al, 2009).…”

“…These transfer of resources between the plants and fungi have profound effect on plant growth, nutrition and ecology, and have been the focus of considerable interest (Smith and Read, 2008;Plenchette et al, 1982, Pearson andTinker, 1975). AMF can improve both plant growths under low fertility conditions, improve plant water balance and help plants to be established in new areas (Jha et al, 2011). Several studies showed that cassava roots establish mycorrhizal association (Sieverding, 1989a;Oyetunji and Osonu, 2007).…”

“…Also, the acquisition of nutrients (e.g. phosphorus and nitrogen) was greater in AM plants than in non-AM plants, and this may have contributed to the greater biomass of AM plants (Jha et al 2012;Liu et al 2014).…”
