ABSTRACT

A type of stigma exists in angiosperms that closes shortly after being touched by pollinators. At present, the research on touch-sensitive stigma mainly focuses on the ecology of pollination, while the dynamic change of stigma closure is rarely studied. The larger the stigma, the faster the temporary closing speed. The dynamic changes of the stigma may be related to its internal physiological mechanism. Similar to the closing of the leaf trap of Venus flytrap, the closing movement of the touch-sensitive stigma was found to be closely related to action potentials. The study of the movement law of Venus flytrap may provide guidance for the biological law of touch-sensitive stigma. In this experiment, two populations of Rhizoma stolonifera in Wuhan Botanical Garden were used as the experimental objects, which were planted in a laboratory with no pollinators and good light and ventilation. The open stigma was selected for uniform mechanical stimulation, and the closing process of the stigma was recorded. Combined with the characteristics of the flower and the number of flowers on the inflorescence, the law of the temporary closing time of the stigma was summarized, and the movement pattern of the closing process was analyzed. The experimental results show that there are significant differences in the temporary closure time of stigma in different populations; the temporary closure time on the same inflorescence has a decreasing trend in the order from bottom to top; and there were also different movement patterns, and the differences in movement patterns were not significantly correlated with population, flower characteristics, or flower position on the inflorescence. This research is a preliminary attempt on the movement law of the touch-sensitive stigma. Through video recording, the speed can be accurately measured by judging the number of frames in the first, middle and last three time periods. However, in the later stage, high-speed cameras and corresponding image recognition software are needed to accurately extract information about the movement of the stigma.
