Abstract

Tomato seed-coat was tested microbiologically. It carries seven species of bacteria, three species of actinomycetes and ten species of fungi, namely : Asper- g -illus -?f lavus A. -fum igatus, -A, niger, -A. ochra-c.e-o, us P-us-ar-iu m -lat eritium, F_. oxgsporum, F-. -s-o, l.ani -P---e ni.cillium -c-i-t, rinum -P, notatum, and Rhizopus- -n- i.icans, The following fungi are isolated from the rhizosphese, rhizoplane and non-rhizosphere soil of tomato : A-s pergill-us flavus, A-. fumigatus, -A, niger, -A.. sydowi, A-. -te rreus, Botrgotrichum pilulife--* rum F-u sarium oxgsporum, F-. solani, Mucor -race mosus, -M. -s phaerosporus, Penicillium notatum, and. Rhizopus nigricans. The fungi reached their optimum number in the rhizosphere region, followed by those in -the non-rhizosphere region and those in the rhizoplane region represent the least number. This holds true for bacteria and actinomycetes also.
