“…A low rate of 160 mg N plant -1 was assigned to the conventional regime. This rate was close to the lowest amount (180 mg N plant -1 ) in CRF delivered to red-seed tree seedlings (Chu et al, 2020), but met the recommended optimum-rate (150-175 mg N plant -1 ) for the culture of Quercus ilex seedlings (Uscola et al, 2015). Another high rate of 600 mg N plant -1 was assigned to the intensive regime.…”

“…This growing container had the same size as those in studies on larch (Zhao et al, 2019), Buddhist pine Xu et al, 2019), and valued shrubs (Aralia elata) . The volume of our container was 0.5 L which was lower than that in the minimum pot but met the recommendation for the culture of red-seed tree seedlings (Chu et al, 2020). Basic properties of the substrate included 120 mg kg -1 NH4 + -N, 140 mg kg -1 NO3 --N and 360 mg kg -1 soluble phosphorus (P).…”

“…Its natural habitat locates in lowelevation broadleaved forest where over-exploitation has continuously occurred. In recent decades, red-seed tree has been listed as an endangered species (Chu et al, 2020;Liu et al, 2011;Zhang et al, 2012). Artificial regeneration is an efficient way to regenerate natural red-seed tree populations.…”

“…Otherwise, controlled-release fertilizer (CRF) is a common and practical means to feed seedlings with the desired nutrient reserve for vulnerable species ( Li et al, 2017;Chu et al, 2019Chu et al, , 2020. The upper limit in studies using CRF for red-seed tree seedlings has been around 600 mg N plant -1 ( Li et al, 2017;Chu et al, 2020). Although the amount of fertilizer appeared to be much higher than fertigation delivery, the active uptake was low due to limited efficiency.…”

Exponential fertilization (EF) can feed seedlings with more nutrients than needed for growth and continuous lighting is expected to reduce the risk of loading at high application rate. In this study, red-seed tree (Ormosia hosiei Hemsley & E. H. Wilson) seedlings were raised by EF at a low rate of 160 mg nitrogen (N) plant-1 (conventional) (N-phosphorus [P]-potassium [K], 12-9-12) and a high rate of 600 mg N plant-1 (intensive), which was adapted from previous studies with large-pot-seedlings. Both fertilizer regimes were nested to either of two light spectra from high-pressure sodium (HPS) and light-emitting diode (LED) sources with three replicates for each combined treatment. Seedlings subjected to the conventional regime in the LED spectrum showed better growth and greater biomass accumulation with higher leaf N and P contents than other ones. In the conventional fertilizer regime, the LED spectrum also resulted in higher photosynthesis shown by more pigments and higher N synthesis than the HPS spectrum. The HPS spectrum strengthened P synthesis in the intensive regime. The antioxidative activity was stimulated by a high dose of EF, hence excessive toxicity was likely induced. We recommend using the normal rate of 160 mg N plant-1 for the culture of red-seed tree seedlings with LED lighting to promote seedling quality without causing excessive nutrient toxicity.

This study evaluates the effects of novel peat-free organic growing media and a novel liquid fertilizer on the biometric features and macronutrient allocation of Quercus robur and Fagus sylvatica seedlings with the view to compare biomass and nutrient allocation of plant organs in seedlings cultivated on peat growing medium against those grown on novel peat-free growing medium and fertilizer. The experimental setup involved four growing medium variants, including peat as the control (R20, R21, R22 and C). The novel growing medium and fertilizer were designed and formulated by the University of Agriculture in Kraków, Poland (UAK). Fertilization used in the state forest nurseries was represented as SR20, SR21, and SR22, while the novel fertilizer of UAK was represented as UR20, UR21, and UR22; meanwhile, SC and UC represented the control growing medium (peat) in both cases, respectively. The experiment was laid in a 2 × 2 × 4 experimental design using five seedlings per treatment. Seedlings were assessed for roots, shoots, and leaves biomass. The allocation patterns highlighted the variability of nutrient allocation within the plants, with more nutrients allocated to the root system. Interestingly, treatment UR22 yielded the highest mean root values, root biomass, and virtually all macroelement allocation. The SC solid fertilizer treatment and the UR22 liquid fertilizer treatment consistently showed superior performance across both species and different plant organs. These findings suggest that these treatments are particularly effective in enhancing the nutrient content of oak and beech seedlings, making them suitable choices for optimizing the growth and health of these species. Seedlings were assessed for roots, shoots, and leaves biomass after the nursery production cycle.

Fine scale sampling reveals early differentiation of rhizosphere microbiome from bulk soil in young Brachypodium plant roots

For a deeper and comprehensive understanding of the composition and function of rhizosphere microbiomes, we need to focus at the scale of individual roots in standardized growth containers. Root exudation patterns are known to vary along distinct parts of the root even in juvenile plants giving rise to spatially distinct microbial niches. To address this, we analyzed the microbial community from two spatially distinct zones of the developing primary root (tip and base) in young Brachypodium distachyon grown in natural soil using standardized fabricated ecosystems known as EcoFABs as well as in more conventional pot and tubes. 16S rRNA based community analysis showed a strong rhizosphere effect resulting in significant enrichment of several OTUs belonging to Actinobacteria, Bacteroidetes, Firmicutes and Proteobacteria. However, microbial community composition did not differ between root tips and root base or across different growth containers. Functional analysis of bulk metagenomics revealed significant differences between root tips and bulk soil. The genes associated with different metabolic pathways and root colonization were enriched in root tips. On the other hand, genes associated with nutrient-limitation and environmental stress were prominent in the bulk soil compared to root tips, implying the absence of easily available, labile carbon and nutrients in bulk soil relative to roots. Such insights into the relationships between developing root and microbial communities are critical for judicious understanding of plant-microbe interactions in early developmental stages of plants.
