33 ℃ high-temperature pretreatment can change the developmental direction and make it from gametal developmental path to sporophyte developmental path. Meanwhile it can make microspores keep higher vitality cell frequency and promote cell division and embryoid induction.

游离小孢子33℃高温预处理，可以改变小孢子发育方向，使其由配子体发育途径转向孢子体发育途径，并使小孢子维持较高的活细胞频率，促进细胞分裂和胚状体发生。

But chromosomal analysis of peripheral lymphocytes can only provide the reasons for 2.4-5% of the spontaneous pregnancy losses, indicating to detect the chromosomal or genetic abnormalities during gametal stage may be more effective.

然而，外周血染色体核型分析仅能为2.4-5%的自然流产患者找到原因，提示研究配子阶段的染色体异常或基因异常对于揭示早期自然流产病因或许更有意义。
