Ratios of nitrogen (N) isotopes in leaves could elucidate underlying patterns of N cycling across ecological gradients. To better understand global-scale patterns of N cycling, we compiled data on foliar N isotope ratios (delta(15)N), foliar N concentrations, mycorrhizal type and climate for over 11,000 plants worldwide. Arbuscular mycorrhizal, ectomycorrhizal, and ericoid mycorrhizal plants we...
It has been known for some time that the root excretion of several species of Solanum stimulates the hatching of larvae from the cysts of the potato eelworm, Heterodera ro8tochien8i8 (Franklin, 1940). The isolation ofthe active principle in root excretion and the investigation of its chemical nature was first attempted, using the leachings from potato plants (Hurst, 1935, 1937), but the method ...
The aim of this paper is to review and compare present European Indian grid code requirements imposed hybrid power plants (HPPs) combining wind, solar storage technologies. Since there are no codes specifically for HPPs, the will plant based on individual renewable technology in HPP. specifies ranges parameters inside which each national transmission system operators (TSO) has specify set (Dani...
