Cytological observation showed that after spraying Paclobutrazol and Unlconazole, the length of the epidermal cells of the stem became significantly shorter but not its width, its pilus epidermidis significantly shorter, the number of cells for each pilus epidermidis significantly less and the diameter of its sieve tube became significantly smaller.

细胞学观察表明，喷施多效唑和烯效唑，其茎秆表皮细胞长径显著变短，短径无显著变化；茎秆表皮毛显著变短，每个表皮毛的细胞数显著减少；茎秆筛管直径显著变小。

The DGCMS plants were complete sterile at the both temperature situations, and there was no pollen sac differentiation and had smaller petals and stamens at the higher temperature situation, but there were 1～4 pollen sacs in each anther and had bigger petals and stamens at the lower temperature situation. The cytological characteristics of the anther development were the same as that of GMS plants in Yi-3AB.

表现质核不育的植株，在高温条件下，花瓣小，表现彻底的pol CMS不育，无花粉囊的分化，在低温条件下，花瓣变大，也表现彻底雄性不育，具有核、质不育的共同特点，每个花药可分化出1～4个花粉囊，但无可育花粉，其雄性败育时期和特点与宜3A相同。

Morphological and cytological observations showed that the pol CMS plants in DGCMS-Yi-3A were complete male sterile, had no pollen sac differentiation and had smaller petals and stamens at higher temperature situation. They were partial sterile, had 1～3 pollen sacs in each anther and had relative bigger petals and stamens at lower temperature situation.

花器形态和花药发育的解剖学观察结果表明，DGCMS-宜3A中表现波里马细胞质雄性不育的植株，其花器形态和花药发育的解剖学特点与pol CMS相同，即在高温条件下，花瓣较小，表现彻底不育，无花粉囊的分化，在低温条件下，花瓣变大，表现部分雄性不育，可分化出1～4个花粉囊，并产生一定数量可育花粉。
