On soil-grown seedlings in pots, and on pure-cultured seedlings in bottles, mycorrhizas grew at approximately one-fifth the rate of equivalent uninfected apices. It was seen in bottle cultures that, because the growth rates of primary and secondary roots usually exceeded the growth rate of the fungus, only a few of these apices came into contact with the inoculum. The slower growth rate, later appearance and the positioning of tertiary root apices, led to many of these becoming invested by fungal mycelium and a considerable proportion of them became converted to mycorrhizas. Mycorrhizal apices were seen to remain active for longer periods, and to grow at more constant rates, than uninfected apices. Possible reasons for this are discussed. |
