Abstract
Abstract Discovery of the role of steroids in relation to growth and asexual sporulation of Phytophthora spp. makes it possible to replace natural media by a synthetic medium. For this purpose an investigation was made into the carbon, nitrogen. vitamin. and calcium requirements of P. cinnamomi Rands. Twenty carbon compounds were tested as major sources of carbon with Ca(NO3)2 and glutamic acid as nitrogen sources. Dextrin, starch, and sucrose were the best sources of carbon for growth and asexual reproduction. Xylose also supported abundant sporulation, although growth was slow. Organic acids and alcohols were poor sources of carbon. The best sources of organic nitrogen tested for growth were glutamine and glutamic acid. Tryptophan, phenyl-alanine, and cystine appeared to be inhibitory. Of the vitamins tested, only thiamine was required by the fungus. Five calcium compounds added singly to the basal medium gave no increase in the growth of the fungus.
