大米和稻谷消毒后,用黄曲霉(Aspergillus flavus Link)、白曲霉(A.ca-ndidus Link)、黑曲霉(A.niger V.Tiegh)、烟曲霉(A.fumigatus Fres.)米根霉(Rhizopus oryzae Went & Geerlings)、薛氏曲霉(Aspergillus cheva-lieri(Mangin)Thom & Church)、禾黑芽枝霉(Clodosporium herbarum(pers.)LK.exFr.)和普通青霉(Penicillium solitum Westling)的孢子单一接种和混合接种,并将水分调节到15.5%、18%,在室温、相对湿度75%的干燥器内储藏15—240天,定期取样观察、测定大米品质各项劣变指标和稻谷种子发芽率。在检查中发现:各种真菌均引起大米品质的劣变;对稻谷种子的发芽率亦有不同程度的影响,尤其以白曲霉更为明显。
Aspergillus flavus Link, A. ca-ndidus Link, A. niger V. Tiegh, A. fumigatus Fres., Rhizopus oryzae Rhizopus oryzae Went & Geerlings, Aspergillus cheva-lieri (Mangin) Thom & Church, Clodosporium herbarum (pers.) LK.exFr.) And Penicillium solitum Westling Spore single inoculation and mixed inoculation, and the water is adjusted to 15.5%, 18%, at room temperature, 75% relative humidity in the dryer for 15 to 240 days, regular sampling observation to determine the quality indicators of rice and rice seeds Germination rate. Found in the inspection: all kinds of fungi cause deterioration of rice quality; the germination rate of rice seeds also have varying degrees of impact, especially Aspergillus oryzae more obvious.
