Research Abstract	Effects of position of panicle and structure of community on occurrence of floret sterility were examined with rice plant in the paddy field in China where the high temperature induced floret sterility often occurs. Simulated experiment showed that fertility of floret flowered at 40cm depth was lower than those flowered higher position. Recovery of the seed set at 40 cm depth by vibration that ensure the pollination suggest that the low wind inside of the canopy induce the poor pollination and sterility.
