Fine-root traits of allelopathic rice at the seedling stage and their relationship with allelopathic potential.

ABSTRACT:

Background

Allelopathic rice releases allelochemicals through its root systems, thereby exerting a negative effect on paddy weeds. This research aimed to evaluate the relationship between fine-root traits and the rice allelopathic potential at the seedling stage.

Methods

Two allelopathic rice cultivars, 'PI312777' and 'Taichung Native1,' and one non-allelopathic rice cultivar, 'Lemont,' were grown to the 3-6 leaf stage in a hydroponic system. Their fine roots were collected for morphological trait (root length, root surface area, root volume, and root tips number) in smaller diameter cutoffs and proliferative trait (root biomass) analysis. Their root-exudates were used for quantitative analysis of phenolic acids contents and an evaluation of allelopathic potential. Correlati
