Pollen Characters

Palynology is the study of fossil pollen (and sometimes plant spores) extracted from lake sediment, peat bog, or other matrices. The most common goal of paly-nological research is to reconstruct the probable character of historical plant communities, inferred from the abundance of species in dated portions of the fossil pollen record. Pollen analysis is an extremely useful tool for understanding the character of ancient vegetation and its response to changes in environmental conditions, particularly in climate. Pollen analysis also has an economically important modem industrial use in the exploration for resources of fossil fnels. Palynology is also used to help reconstmct the probable habitats and foods of ancient humans and of wild animals. 

CLASSICUSi Sounds philosophical again. No, perhaps not always. Theoretically you can expect that the macromorphological characters suggest one sort of grouping, while e.g. the chemical and pollen, and wood anatomical results suggest another one, richer in correlating characters. Of course I take then the subdivision on account of macromorphology, because that is most practical.. ... 

Even with this redncing character, sucrose and invert sugar are not very reactive in the tea making process. Herbal teas contain numerous chemical compounds, none of which react with sucrose, glucose or fmctose. In addition to invert sugar and about 20% water, honey also contains a complex mixture of compounds (minerals, pollen, substances produced in the bodies of bees). The possible reaction of these active ingredients with herbal tea has not been studied in detail yet. However, experience shows that honey does not interfere with the efficacy of herbal teas. 

The expression c.f the high oleic character took place exclusively in the seed tissues of the mutant during the active synthesis of reserve lipids. No other tissues like leaf, stem, root, pollen and even hull or seed membrane had hi(]h levels of oleic acid. Young seeds of both normal and high oleic liiutant had similar fatty acids composition in the different lipid classes (table 1). However, the fatty acid composition of adult seeds depended on the...
