The mature egg cell was an inactive cell with only a few polysomes. At the early zygote stage, a large number of ribosomal precursors were produced by the nucleolus, and many polysomes appeared in the cytoplasm, which suggests a high level of metabolism. Zygote at the dormancy stage had a small nucleolus and marked decrease in ribosomes, as shown by a few polysomes, which suggests decreased metabolism. Zygotes in the prophase of mitosis and two-celled proembryo became active again in metabolism, for a prominent nucleolus, high density of ribosomes and increased number of polysomes in the cytoplasm.

结果如下：在成熟卵细胞中多聚核糖体数量不多，且细胞代谢活性较弱；初期合子内，核仁大量合成核糖体前体物质，胞质中多聚核糖体数目众多，细胞代谢活性较强；休眠期合子的核仁变小，胞质中核糖体数量急剧减少，仅有少量多聚核糖体，细胞代谢活性较弱；合子分裂前期和二细胞原胚期，核仁显著，胞质中核糖体的密度增加，出现大量多聚核糖体，细胞代谢活性较强。

The Evolutional manners and dimensional rules of γmatrix and γ'precipitates in the [001], [110] and [111] oriented specimens of nickel-base single crystal superalloy CMSX-4 during the tensile creep at 1253 K and 350 MPa were studied.The effects of the change in characteristic dimensions of γand γ' phases on the strain and strain rate were compared for the differently oriented single crystal specimens.It was found that the effect of change in mean width of γchannels along the direction of directional coarsening of γ' precipitates(the lamella spacings between adjacent rafted γ'precipitates)on the strain and strain rate is remarkable.

It was typically indirect effect that the following variations induced in the progenies of endosperms implanted by heavy ion beams were discovered. 1 In comparison with control, there were very high differences in biological trait, anti-oxidation enzyme activity, MDA content and protein content, chromosome aberration rate and micro-nucleus rate in M1 generation. 2 Shorter stem variants and purple stem mutants were analyzed by RAPD and AFLP. The analytic results showed that the sequences of their DNA were changed, so those variations were not physiological damage only. And there were differences among M2 generation plants of the same sort of variants or mutants, it was indicated that M2 generation may be in disjunction.

M1代的生物学性状、幼苗的抗氧化酶活性、MDA含量、蛋白质含量和染色体畸变率及微核率等发生了较大的变化。2）对其矮杆变异株和紫色茎杆突变体（M2）做RAPD和AFLP分子鉴定等研究，结果显示了矮杆变异体和紫色茎杆突变体的DNA序列发生了改变，而非仅仅产生生理损伤；同一种变异体或突变体，在M2代单株间也存在着明显的差异，表明它们可能还处于分离状态。

RESULTS: The rates of germinal vesicle breakdown were 98%, 22.2%, 40.1% and the rates of the first polar body (PB1) extrusion were 77.7%, 15.5%, 27.6% for M16, Hx and FA groups, respectively. The rates of GVBD and PB1 were all increased with the addition of FA compared with the Hx groups and comparison was significant (P.05). Hx and FA did not influence chromosome, but FA reversed the size of metaphase spindle elongated by Hx.
