A study has been made to determine the qualitative nature of the fungus flora of old citrus soils of southern California, and to ascertain whether or not the growth of the citrus plant exerts a selective action on the nature of this population. Several species of Penicillium, Aspergillus, Trichoderma, and, occasionally, of other genera constituted the bulk of the mold population of noncitrus soils. The greater part of the fungus flora of the old citrus soils, on the other hand, consisted of Fusarium spp. I and 2, Fungus DI, Pyrenochaeta sp., and various species of Penicillium. Fungus DI and Pyrenochaeta sp. were not found in noncitrus soil but were isolated consistently in relatively large numbers from all old citrus soils, Fusarium spp. I and 2 were found inboth old citrus and noncitrus soils but in much greater concentration in old citrus soils. Fusarium sp. I was isolated repeatedly from apparently healthy, surface- sterilized citrus feeder roots. |
