A Gaussian random wavefunction that satisfies Dirichlet and Neumann conditions locally on a convex circular boundary is introduced. The average of the square of the wavefunction and its derivatives are computed and their asymptotics studied in the se

Four Frankia-Casuarina endosymbiont strains were tested for their infectivity and effectiveness on C. equisetifolia plants after 1 d, 3 and 6 months of Frankia storage at 7, 28 and 40 degrees C as liquid-cultures and polyacrylamide gel (PAG)-immobili

The tolerance of nickel by Frankia in culture and in symbiosis with Alnus was determined. Yield of three Frankia strains was not affected significantly by 2.25 mM nickel when cultured in propionate medium containing hydolysed casein as nitrogen sourc

Summary Lotus pedunculatus is a common legume of wet, acidic soils. Earlier laboratory studies have identified adaptations to nodule form and function that facilitate N2-fixation in flooded conditions. However, the strategies that ensure satisfactory

Exposure of the roots of Alnus glutinosa (L.) Gaertn. to white light stimulated within 5 days a substantial increase in the content of quercetin and kaempferol, two major flavonols in acid hydrolysates of both roots and root exudates. Both compounds

The growth of threeFrankia strains (HFPCcl3, ORS021001, ORS020607), isolated from nodules ofCasuarina, was unaffected by 5–15 μmol/L quercetin. Re-isolation ofFrankia strain HFPCc13 fromCasuarina root nodules was carried out with the addition of 1

Comparison of the effects of temperature on the growth in culture (increase in protein) of Frankia showed that three strains isolated from Casuarina were more tolerant of high temperature (45°C) than a strain from Alnus rubra. Optimal temperatures f

summary Casuarina eqisetifolia (L.) (L.) seedlings, grown with a limiting supply of mineral N and P, were inoculated with either Frankia or Glomus fasciculatum E3 and subjected to delayed inoculation with the second microsymbiont. Comparison with see
