RELATION BETWEEN CHANGES IN PHOTOSYNTHETIC RATE AND CHANGES IN CANOPY LEVEL CHLOROPHYLL FLUORESCENCE GENERATED BY LIGHT EXCITATION OF DIFFERENT LED COLOURS IN VARIOUS BACKGROUND LIGHT

Relation between Changes in Photosynthetic Rate and Changes in Canopy Level Chlorophyll Fluorescence Generated by Light Excitation of Different Led Colours in Various Background Light

Using light emitting diodes (LEDs) for greenhouse illumination enables the use of automatic control, since both light quality and quantity can be tuned.Potential candidate signals when using biological feedback for light optimisation are steady-state chlorophyll a fluorescence gains at 740 nm, defined as the difference in steady-state fluorescence

Comparative analysis of nitrogen content and its influence on actinorhizal nodule and rhizospheric microorganism diversity in three Alnus species

Alnus spp.(alder) are typical nonleguminous nitrogen-fixing trees that have a symbiotic relationship with Frankia.To explore the differences in nitrogen-fixing microorganisms between three alders (A.cremastogyne, A.glutinosa, and A.formosana) with different chromosome ploidies, the community structure and compositional diversity of potential nitrog

Numerical Models for Exact Description of in-situ Digital In-Line Holography Experiments with Irregularly-Shaped Arbitrarily-Located Particles

We present the development of a numerical simulator for digital in-line holography applications.In-line holograms of arbitrarily shaped and arbitrarily located objects are calculated using generalized Huygens-Fresnel integrals.The objects are 2D opaque or phase objects.The optical set-up is described by its optical transfer matrix.A wide Sweater Dr
