Backgrounds and aims Allelopathic species can be key components of successful integrated weed management. We evaluated the suppressive potential of buckwheat ( Fagopyrum esculentum ), simulating the effect allelochemicals exert through crop residues or root exudates on weeds, with minimal harm to crops. Methods We investigated the effect of two buckwheat (BW) water extracts (weight ratio 1:5 and 1:10) on seed germination and root growth of weeds ( Echinochloa crus-galli , Cynodon dactylon , Amaranthus retroflexus , Setaria italica ) and crops (barley, chickpea, cress, lentil, quinoa, soybean and tobacco) in Petri dishes. Then, a pot experiment was conducted to test BW’s root exudates on the growth of weeds ( Abutilon theophrasti and Amaranthus retroflexus ) and crops (chickpea and lentil), either intercropped with BW, or supplied with leached water from BW pots. The content of quercetin and rutin was assessed in all BW samples. Results Both experiments demonstrated a suppressive effect of BW, with intensity varying by species susceptibility. Quercetin and rutin were found in ground buckwheat and in water extracts, but only quercetin in leached water. In the germination experiment, osmotic potential of the water extracts may also be a factor reducing germination rate, but the effect was not unequivocal. Conclusion This study confirms the potential of BW for weed suppression in low-input systems: 1) the inhibition of weed germination from BW water extracts can support its use as mulch from crop residues; 2) since some crops were also affected in both experiments, BW use in intercropping or cover cropping should be adapted to the crops. Further research is needed to understand the mechanisms of buckwheat allelopathy and to test these results in field conditions.

Background and aims There is considerable interest in how plants allocate phosphorus (P) and how this varies by environment. How leaf P fractions change with soil P supplies and soil type is essential to understand the roles of P in storage, structure and biochemistry including photosynthesis. Here, we contrasted the P allocation patterns for native woody plants in south-eastern Australia on soils derived from either P-poor sedimentary or P-rich igneous parent materials. Methods We measured total leaf P and four leaf P fractions: inorganic phosphate (P i ), metabolite P, nucleic acid P, and lipid P for 33 native species. We also measured photosynthetic capacity ( Asat ) for species across four sites with contrasting soil P and parent material types: high total soil P from basalt versus low total soil P in sands. Results The leaf P i fraction scaled consistently with total leaf P within and across the high-P versus low-P sites. Species growing on high P soils from basalt tended to have similar P fractions of total P to those of species on low P soils, except for the lipid P fraction which was greater for species at high P sites. There was a substantial reduction in P allocated to the lipid fraction for species on low P soils, especially in Proteaceae species. Leaf photosynthetic P-use efficiency was significantly higher with lower leaf P concentration. Conclusion The adaptive strategy of reducing phospholipids in leaves occurs in multiple species in low-P environments, including non-Proteaceae. This resulted in species from more than one plant family maintaining lower leaf P concentrations on sedimentary-derived soils than on igneous soils, thus achieving more efficient P use in photosynthesis at low P.
