Amino-acid biostimulant effects on Pinus radiata seedling growth, physiology, root mycobiome and nitrogen assimilation
  • Description

    Radiata pine seedlings were grown under controlled conditions with equivalent total N supplied either as inorganic fertilizer or an amino-acid–based biostimulant. We measured morphological traits (height, collar diameter, biomass), needle chlorophyll and fluorescence, hormone profiles, and root fungal communities (ITS2 amplicon sequencing + DADA2/phyloseq analysis). Integrative gradient-boosting modelling identified key fungal taxa driving biomass responses. 130 raw MiSeq ITS paired-end FASTQ files (fungal community sequencing) Morphological_Physiological_data.xlsx: seedling height, collar diameter, shoot/root biomass, chlorophyll fluorescence, total nitrogen, etc. Hormonal_data.xlsx: needle phytohormone concentrations (IAA, GA, ABA, etc.) Metadata_microbial_population_analysis.xlsx: sample metadata
