Anthocyanin Production

We have tested the tacit assumption that the location of anthocyanic cells within a leaf affects the quality and quantity of light that is absorbed. Leaf optics are described for Quintinia serrata A. Cunn., a native New Zealand tree that is polymorphic for anthocyanin distribution and concentration. Anthocyanin production enhanced the absorptance of green-yellow wavelengths in proportion to pigment concentration. The reflectance of red light was independent of leaf anthocyanin content. Variation in the location of pigmented cells could not account for differences in leaf optics. The effects of anthocyanin on PAR absorptance were consistent across six further, unrelated species that bore red leaves. We conclude that anthocyanin concentration, rather than its histological distribution, has the greater impact on leaf optical properties.

Developement of computer technology provides much improvements on electron microscopy, such as simulation of images, reconstruction of images and automatic controll of microscopes (auto-focussing and auto-correction of astigmatism) and design of electron microscope lenses by using a finite element method (FEM). In this investigation, procedures for simulating the optical properties of objective lenses of HREM and the characteristics of the new lens for HREM at 200 kV are described.The process for designing the objective lens is divided into three stages. Stage 1 is the process for estimating the optical properties of the lens. Firstly, calculation by FEM is made for simulating the axial magnetic field distributions Bzc of the lens. Secondly, electron ray trajectory is numerically calculated by using Bzc. And lastly, using Bzc and ray trajectory, spherical and chromatic aberration coefficients Cs and Cc are numerically calculated. Above calculations are repeated by changing the shape of lens until! to find an optimum aberration coefficients.
