磷水平对接种丛枝菌根真菌甜玉米苗期生长的影响
Effects of phosphorus concentration on growth of Arbuscular mycorrhizal sweet corn
摘要
Abstract
The Arbuscular mycorrhizal (AM) was inoculated to the host plant sweet corn with different phosphorus concentration (PC) and their effects on infection rate of mycorrhizae,N and P content in shoot and mycorrhizal root of corn,Arg content in mycorrhizal roots were investigated.Results showed that:AM fungi infected of the corn root system and significant differences of infection rates were observed at different PC.The infection rate at low PC was higher than that at high PC.The numbers of spores increased with the increment of PC.The fresh weight of the external hyphae inside the chamber in P40 was the highest.The biomass and N and P content in shoot and root of mycorrhizal sweet corn were obviously higher than those of control group.Moreover,low PC significantly promoted the increment of fresh weight in shoot and mycorrhizal root of sweet com.The total N contents in shoot and root of mycorrhizal sweet corn were highest in P40,P80 and P20,P40.The total P contents in shoot and root of mycorrhizal sweet corn were highest in P80 and P160.Arg content in mycorrhizal root was highest at low PC (P20).This result revealed that the sweet corn growth was promoted by inoculating Arbuscular mycorrhizal and associated with the exogenous P concentration.关键词
