ABSTRACT

    An effective method obtained from compost water extracts was to incubate compostsolution at 60oC in water bath for about 3 hrs and to centrifuge to get supernatant as final compost extract. Pollen tubes of Solanum melongena L. increased their length with the@increase of dilution rates of compost extracts enriched to their culture media. Compared with matured composts, contents of ammonia-N and volatile organic acids of un-matured compost were high. Extracts of un-matured compost depressed the elongation pollen tubes of both Solanum melongena L. and Stewartia pseudo-Camellia Maxim. as well as the rates of germination and elongation of roots of Brassica campestrics L.

Keywords: compost, maturity, pollen culture, Solanum melongena L.and Stewarlia pseudo-Camellia Maxim
