Abstract
Transplantation shock can severely reduce plant yield by damaging roots and impairing water and nutrient uptake, making plants more vulnerable to stress and infections. This study investigates whether arginine, in the form of arGrow Granules, can act as a biostimulant to reduce transplantation shock and promote spinach seedling growth.
Spinach seedlings were transplanted into humus-rich muddy moraine soil, with arGrow Granules placed under the roots of the biostimulant group. Stress symptoms (bolting, leaf discoloration, wilting, and death), leaf size, leaf count, plant height, and biomass (leaf and root) were measured.
The biostimulant group that received arginine at transplantation exhibited more stress symptoms and had smaller leaves, height, and biomass compared to the control group. Therefore, this study does not support arginine as a biostimulant to reduce transplantation shock in spinach. Future studies could explore different soils, dosages, and application methods for non-forestry applications.
Transplantationschock kan minska skörden genom att skada rötterna, försämra näringsupptag och öka mottaglighet för stress och infektioner. Det har bevisats i flera andra studier att biostimulanter kan lindra transplantationschock och öka tillväxten vid transplantation. Denna studie undersöker om en biostimulant bestående av arginin i form av arGrow Granulat kan främja tillväxt och rotutveckling hos spenatplantor.
Krukor fylldes med humusrik lerig moränjord och krukorna tillhörande behandlingsgruppen fick en dos arGrow Granulat i substratet. Därefter transplanterades spenatplantor till alla krukor. Under studien mättes stressymtom (blomning, missfärgning, vissnande), bladstorlek, bladantal, höjd och biomassa.
Resultaten visade att argininbehandlade plantor uppvisade fler stressymtom samt mindre blad, höjd och biomassa jämfört med kontrollgruppen. Studien stödjer därför inte användning av arginin som biostimulant för att minska transplantationschock hos spenat. Vidare studier med annan jord, dosering och appliceringsmetod kan ge mer insikt.
