Abstract：In order to find out the reason why fruit setting of short-internode watermelon is difficult,the pollen morphology and viability of short-internode watermelon and normal diploid watermelon were analyzed.The results showed that the pollens of the common diploid watermelon were short ellipsoid shaped with the same size,and the average P/E ratio was 1.34.The pollens of short-internode watermelon varied in size,many anomalous and empty pollens were observed,the polar axis and equatorial axis were difficult to distinguish,the average P/E ratio was 1.09.The 4 h germination rate was significant differences between normal watermelon(98％) and short-internode watermelon(9％) pollens.So the lower fruit setting rate of short-internode watermelon might be caused by anomalous pollens and worse germination rate.
