Abstract

Plant growth promoting activity of quinolinone metabolites, 2-(2-hepteny)-3-methyl-4-quinolinone (1), 2-heptyl-3-methyl-4-quinolinone, and 2-nonyl-3-methyl-4-quinolinone, produced by Pseudomonas cepacia and ethyl 2-methyl-3-alkyl-4-quinolinone carboxylates chemically synthesized were tested by using seed-germination assay, growth increments in plant height after foliar applications. Plant height increment, fresh weight, and the number of fruits were measured after seed-soaking and drench treatment. Compound 1 among the natural products showed a consistent growth promoting effect in seed-germination and plant height after a foliar application. After a seed-soaking and drench treatment, compound 1 and synthetic ethyl 2-methyl-4-quinolinone-3-carboxylate (5) showed a significant enhancement in fresh weight and the number of fruits after harvest. Compound 1 and 5 increased the number of fruits per plant by 44% and 84% over the control, respectively.

Pseudomonas cepacia로부터 유래한 quinolinone 대사물질인 2-(2-hepteny)-3-methyl-4-quinolinone (1), 2-heptyl-3-methyl-4-quinolinone, 2-nonyl-3-methyl-4-quinolinone 및 합성물질 ethyl 2-methyl-3-alkyl-4-quinolinone carboxylate의 식물생장촉진 효과를 보기 위해 종자발아검정 및 경엽처리 후의 생장량을 측정하였다. 또한 종자침지 및 관주 처리후의 초고, 생체중, 과실수도 조사하였다. 화합물 1은 종자발아 효과와 경엽처리 후에 일관된 생장촉진 효과를 보였다. 종자침지와 관주처리 후에, 화합물 1과 합성물질 ethyl 2-methyl-4-quinolinone-3-carboxylate (5)를 처리한 식물에서의 생체중과 과실수는 크게 증가하였다. 화합물1과 5는 대조관보다 각각 44%와 84%의 과실수 증가를 나타냈다.
