INFLUENCES OF ARBUSCULAR MYCORRHIZAL FUNGI ON GROWTH AND MINERAL ELEMENT ABSORPTION OF CHENGLU HYBRID BAMBOO SEEDLINGS

Abstract

Arbuscular mycorrhizal (AM) fungi can enhance mineral nutrient and growth of host plants. In the paper, growth and mineral element absorption of Chenglù hybrid bamboo (Bambusa pervariabilis × B. grandis) seedlings inoculated with four AM fungi strains(Glomus intraradices, BEG Number193 and 141; G. mosseae, BEG Number167; G. etunicatum, BEG Number168) were studied. The results showed that AM fungi promoted the growth of bamboo seedlings. The biomass of Chenglù bamboo inoculated by AM fungi increased 1.84 (BEG167), 1.73 (BEG193), 1.59 (BEG168) and 1.54 times (BEG141) than that of the control respectively. Shoot number and diameter, total leaf area per plant, P and K concentration in plant as well were significantly increased by the inoculation of BEG167 and 193, which had better mycorrhizal effect and could make an important contribution to Chenglù bamboos production.
