Wood anatomy of the three species of Cneorurn is described qualitatively and quantitatively. The species differ in features related to ecology and form a clear series in this regard. The wood features of the family can all be matched by some Rutaceae and Simarubaceae, and the characteristics of Cneoraceae are listed in this connection. Nearly as many features are shared by Cneoraceae with Anaca...
Scattered intensity measurement is a commonly used method for determining the size of small particles. However, it requires calibration and is subject to errors due to changes in incident irradiance or detector sensitivity. Analysis of two-dimensional scattering patterns offers an alternative approach. We test morphological image processing operations on patterns from a diverse range of particl...
Pollen morphology is an important parameter. In this study, the pollen of selected in 10 grape cultivars were examined by SEM (scanning electron microscopy). The surface features observed, such as length, width, and P/E ratio pollen. differed some microstructural characteristic. width exhibited significant according to varieties (10.12-22.44 µm). Smilarly, statistical difference occurred among ...
Adults of many insect species often become contaminated with pollen grains when feeding. Identification of plant hosts for M. separata moths could increase our understanding of their geographic origin and the coevolution of M. separata moths and their host plants. However, identifying the diet of noctuid moths using traditional direct observation is limited by their nocturnal and flight habits....
