Setaria: The effect of root limitation on biomass in Setaria
Keywords:
Setaria, root biomass, shoot biomassAbstract
This experiment indentified the relationship between root biomass and growth using Setaria. We found plants with the most root space and added nutrients showed the best overall growth, plants in large pots with added fertilizer produced more root and shoot biomass, little pots without fertilizer out performed the big pots without fertilizer when comparing root bio mass, a significant effect of pot size on the ratio of root to shoot biomass in the absence of fertilizer, when fertilizer was added, the pot size was insignificant, plants with restricted root space and added nutrients showed improved growth over those without added nutrients, and large pots showed more shoot biomass at the time of harvest.ÂReferences
