Abstract: Basing on the length measurments of the guard ceIls in wheat pollen plantlets and analysis of variance on the data, the author obtained the results as follows:(1)The form and size between the wheat haploids and diploids were quite similar,but the difference between the respective stomatal length of them was significant.(2)As regards the pollen plants obtained from the F 1 hybrlds,they were notably segregated in character,but the difference of the dto,atal length was not significant either among the haploids themselves or among the diploids.Hence, this method may be used to identify the ploidy-level of wheat pollen plantlets, and this process easier and quicker could be used than the chromosome-count in the root-tip cells.
