摘要：

The effects of concentration of the inoculum on growth of the host and level of infection were investigated in mycorrhizal tomatoes. All concentrations of the endophyte, ranging between 225 and three chlamydospores per plant, led to significant stimulation of growth. Measurements of height of plants and length of leaves during growth indicated that inocula containing low numbers of spores stimulated the host less than more concentrated inocula. Plants inoculated with high numbers of spores produced more upper and retained more lower leaves whereas plants inoculated with low numbers retained more lower leaves than uninfected control plants. Dry weight determinations of the foliage made at the end of the experiment showed that all inoculated treatments were larger than the control treatments. The concentration of spores in the inoculum did not appear to influence the final level of infection. Copyright © 1969, Wiley Blackwell. All rights reserved
