Abnormal physiological responses of plant cultures
such as shoot tip necrosis, callus, and hyperhydricity are some
of the most difficult challenges in shoot micropropagation,
and their causes are not well understood. Five Murashige and
Skoog...

We explore selected aspects of J.-Y. Parlange’s contributions to hydrological transport of
solutes and sediments, including both the laboratory and field scales. At the laboratory scale,
he provided numerous approximations for solute transport...

Field surveys were conducted by collecting soil samples to estimate
nematode densities in soil from winter wheat, spring wheat, spring
barley, and spring legumes (lentil, chickpea, and pea) fields during
2010 and 2011. Pratylenchus spp. were...
