摘要: 本文根据对小麦花粉植株叶片气孔保卫细胞长度的测量及其变异性分析,得到以下结果:小麦花粉单倍体(1n)与二倍体(2n)之间虽形态十分相似,但其气孔长度差异显著;亲自杂交一代的不同花粉植株,性状分离很大,但其单倍体之间或二倍体之间,气孔长度差异不显著。因此,用测量气孔长度鉴定小麦花粉植株倍性是可行的,且方法简便、快速。

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.
