[Objective] The research aimed to study a new whole clearing and preparation technology.[Method] After young seeds of Stephania sp.preserved in the alcohol solution,as well as the fresh pistil and nucellus of Sorghum bicolor were separated,they were soaked and cleared in the solution of 84 disinfectant.And the plant materials could be mounted by using three methods.[Result] The globular embryos and heart-shaped embryos at different stages of Stephania sp.as well as the pistil,nucellus,embryo sac,hypostase o...
[ Objective] The aim of this study was to solve the problem of photographing small flowers and fruits with a common digital camera in field. [Method] Firstly, the photographic mode of a common digital camera was set as ＂macro＂ （or ＂soft snap＂ ） and ＂flash off＂. Secondly, the small flower or fruit was magnified with a magnifying glass, and then the magnified flower or fruit was automatically focused with the digital camera lens. After automatic focusing, the shutter button was pressed and the photograph finished. [Result] With this method, the clear inflo- rescence or floral photographs of Eragrostis pilosa （ Gramineae ） , Bidens biternata （Compositae） and Tribulus terrester （Zygophllaceae） were obtained in field. [ Conclusion] The optical system of a digital camera has been changed by the magnifying glass, which improves the photographic function of a common digital camera to small flowers and fruits, and also easily gets their clear photographs.
