Abstract Due to challenges associated with lavender propagation, Texas hybrid (lavandin) growers require revised propagation information. Therefore, experiments investigated effects of media and plant growth regulators (PGR) on rooting three different lavandin (Lavandula x intermedia) cultivars. PGRs applied cuttings were naphthaleneacetic acid (NAA), or indole-3-butyric (IBA) at concentrations...

We present a numerical analysis of how vortex rings from Sphagnum moss disperse their spores. Comparisons of the results of our CFD model with data measured from high-speed video reveal that the pressure inside the capsules is only 2 atm, which is significantly less than has been reported in the literature. We show that vortex rings produced by these pressures do not optimize the impulse to the...

Soil and plant tissues were used to examine the effect on the release of dissolved organic carbon (DOC) of rinsing over time at two temperatures and under oxic and anoxic conditions in a laboratory incubation. The release of DOC over 60 days of incubation ranged from 0.5 to 189 mg DOC g 1 oven-dry material and was correlated inversely with the degree of decomposition of the material: fresh mapl...
