Effects of AMF inoculation on growth and nutrient quality of asparagus plant under protected cultivation
In order to explore the potential impact of arbuscular mycorrhizal fungi (AMF) on asparagus growth, yield and nutrient quality, asparagus seedlings, cultivar 'Jinglvlu' was inoculated with Glomus mosseae (GM). Seedlings were then planted in high plastic tunnel and non-inoculated seedlings were the control. Asparagus plants inoculated with AMF had 46% greater fresh weight, 36% higher dry weight but 13% fewer stems than the untreated control. Chlorophyll content in asparagus leaves of AMF inoculated seedlings was 32-36% higher than the control. The asparagus nutrient absorption ability was also significantly improved by AMF inoculation. Fern P, K, Mg, and Mn content was significantly greater than the control, but N, Cu, Zn contents were not different. Asparagus fern rutin and saponins levels were also significantly higher in AMF inoculated plants. In conclusion, these findings suggest that AMF inoculation seedlings will improve nutrient absorption and nutrient quality of asparagus.
