  1. 1. Korrelation mellan grobarhet och livskraft i frötester och fältuppkomst hos spenat, Spinacia oleracea L.

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Isabella Kleman; [2016]
    Keywords : spenat; grobarhetstest; fältuppkomst;

    Abstract : För att kunna förutsäga vilken mängd utsäde som krävs för att få en önskad planttäthet i fältet är det viktigt att veta vilken fältuppkomst som kan förväntas. För att förutsäga detta används grobarhetstest. Detta arbete undersöker hur den uppmätta grobarheten korrelerar med den faktiska fältuppkomsten hos Spinacia olereacea L. READ MORE
