Effects of Fulvic Acid on Growth and Nitrogen Utilization Efficiency in M9T337 Seedlings.

ABSTRACT: Both fulvic acid (FA) and nitrogen (N) play important roles in agricultural production in China. Plants typically show a higher nitrogen utilization efficiency (NUE) under FA application. However, the role of FA application in apple growth and NUE remains unclear. A hydroponic culture experiment was performed, and M9T337 seedlings (a dwarf apple rootstock) were used as the experimental subjects. The biomass, photosynthesis, accumulation, and distribution of photosynthates, N absorption and assimilation, and relative gene expression in the seedlings were examined after treatment with five different concentrations of FA (0, 60, 120, 180, and 240 mg·L^-1, represented by CK, FA1, FA2, FA3, FA4, respectively). The results showed that the seedling dry weight and ¹⁵NUE were e
