Creped cellulose paper covered with sand for Glycine max, Helianthus annuus, Phaseolus vulgaris and Zea mays

摘要

The germination medium top of creped cellulose paper without a blotter and covered with a V2-%-inch (1.27-1.91 cm) layer of sand (TCS) is currently utilized in AOS A Rules as a growing medium for six species: Glycine max, Gossypium spp., Helianthus annuus, Phaseolus vulgaris, Pisum sativum and Zea mays. A peer validation study showed no significant differences between currently used ISTA media and top of crepe paper with sand (TPS) medium for Glycine max and Zea mays. However, for Phaseolus vulgaris, the TPS medium produced significantly different but higher results than the between-paper (BP) method. For Helianthus annuus, TPS produced significantly higher results than BP, but no significant difference to sand and organic growing media. These results support the inclusion of TPS as a new testing medium option for ISTA laboratories.
