Palynology, one science of plant's pollen and spores, has been proven to be a new frontier discipline. Because of the characteristics of pollen and spores, such as small size, light weight, large amount, and difficult to be found, they can leave physical evidence and provide new clues to solve a case. Therefore palynology has a good prospect for practical application in forensic medicine. The paper intends to analyze the advantage and limitation of palynology in forensic medicine by reviewing its general characteristics, classification, morphology, and disseminating circadian rhythm. We hope to provide some reference to apply palynology in forensic medicine.

2.Recent advances of amplified fragment length polymorphism and its applications in forensic botany.
Journal of Forensic Medicine 2008;24(5):375-377
Amplified fragment length polymorphism (AFLP) is a new molecular marker to detect genomic polymorphism. This new technology has advantages of high resolution, good stability, and reproducibility. Great achievements have been derived in recent years in AFLP related technologies with several AFLP expanded methodologies available. AFLP technology has been widely used in the fields of plant, animal, and microbes. It has become one of the hotspots in Forensic Botany. This review focuses on the recent advances of AFLP and its applications in forensic biology.

The study was conducted to explore the response of growth and yield of Tulipa edulis to flower bud removal and artificial pollination. And flower bud removal and artificial pollination were carried out in the squaring period and bloom stage respectively. The morphological index and biomass indicators were determined and the yield was counted in harvest time. Result showed that flower bud removal was beneficial to the growth of T. edulis, resulting in increasing growth index, biomass as well as the yield of bulb. The diameter and dry weight of T. edulis fruit by artificial pollination were increased significantly compared with the control. Seed setting percentage increased to 100%, and the number of seed as well as the single grain weight increased by 69.03% and 16.48%, respectively, which did not significantly affect the bulb production. In conclusion, Flower bud removal treatment accelerates bulb biomass increase, so as to improve its yield. Artificial pollination raised significantly seed setting percentage, seed number as well as the single grain weight.

Forensic botany is a study of judicial plant evidence. Recently, researches on DNA labeling technology have been a mainstream of forensic botany. The article systematically reviews various types of DNA labeling techniques in forensic botany with enumerated practical cases, as well as the potential forensic application of each individual technique. The advantages of the DNA labeling technology over traditional morphological taxonomic methods are also summarized.
