Lead-resistant industrial hemp germplasm resource identification method

Fuente: WIPO "industrial hemp"
The invention discloses a lead-resistant industrial hemp germplasm resource identification method, and belongs to the technical field of plant restoration of heavy metal contaminated soil. The methodcomprises the steps that a lead-containing test solution is prepared, and industrial hemp seeds are put into the test solution for germination culture; the subordinative function value Xi of the seedling-stage lead-resistant index lead damage rate of industrial hemp and the seedling-stage lead damage index Y, according to the seedling-stage lead damage index Y, a to-be-identified industrial hemp germplasm resource is subjected to seedling-stage lead-resistance classification; a base fertilizer and a soil modifier are added into a prepared lead-containing soil mixture, the industrial hemp whichis high in seedling-stage lead-resistance grade is sown and placed in a greenhouse to be cultured for 3-4 months, and mature industrial hemp is obtained; the industrial hemp is harvested, the subordinative function value Gi of the growth-stage lead-resistant index lead damage rate of the industrial hemp and the growth-stage lead damage index Q are calculated, and according to the growth-stage lead damage index Q, the to-be-identified industrial hemp germplasm resource is subjected to growth-stage lead-resistance classification. The method is simple, short in period and low in cost.
