Effect of choline amino acid ionic liquids on maize seed germination and endogenous plant hormone levels.

ABSTRACT: Prior research has established choline-based ionic liquids (ILs) as safe for various organisms. However, their impact on plants has been underexplored. To identify effective eco-friendly ILs, we synthesized seven choline amino acid ([Chl][AA]) ILs and analyzed their physiological influence on maize seed germination. In contrast to the traditionally used N-octyl pyridinium bromide IL, these seven [Chl][AA] ILs exhibited substantially lower toxicity. Moreover, within a broad treatment concentration range (10-100 mg L^-1), these ILs notably enhanced maize germination indices and root and shoot growth. Specifically, treatment with 100 mg L^-1 choline tryptophan resulted in a 21.2% increase in germination index compared to those of control maize. Compared to the contr
