本文综述了8个已应用于商业化育种的甜玉米胚乳突变基因的染色体位点、编码的产物及其表现型，介绍这8个甜玉米胚乳突变基因的分类、遗传效应及其互作效应，并提出其在我国甜玉米育种中的应用策略，旨在为甜玉米的深入研究和开发利用提供参考。

Except on the testis tissues,the expression of ZFY gene were found on the kidney tissues of human embryo or rat, brain vesicles〔rat embryo 13 days〕,and sclerotome cells〔rat embryo 13 days〕 It is possible that because kidney and genital system come from same origin,ZFY gene expressed on the kidney tissues too, the expressive function of ZFY gene on the embryonic brain vesicles and sclerotome cells is not yet clear.

除了在睾丸组织上表达外，ZFY基因还在肾脏组织及鼠胚脑泡(胚胎13天)，生骨节细胞(胚胎13天)上表达。在肾组织上表达可能是肾脏与生殖系统起源相同有关。在胚脑泡及生骨节细胞上表达其作用不清楚。

When GA_3 was used before flowering at the concentration of 25mg/kg in KYOHO, the seedlessness was due to not being fertilized and when used after flowering in MEI GUI XIANG, the seedlessness was due to the degeneration of fertilized embryo.

巨峰花前25mg·kg~(-1)处理导致胚不能正常受精而形成无籽果实；玫瑰香花后GA_3处理可能使受精胚退化而无籽。

Storage studies also found that the effect of temperature and time on the physical and chemical qualities of mei is not significant. Good storage stability characteristics can be obtained for semidried mei preserved by reused brine.

储藏实验之结果发现储藏温度及储藏时间对各组梅胚理化性状的影响均不显著，以废盐液腌渍之梅胚具备良好的稳定性及储藏性。

Results indicated that semidried mei preserved by reused brine or regenerated salt have higher values in acid, soluble solids, and salt contents than those prepared from fresh salt. However, there is no significant difference in sensory evaluation. These results implied that the reuse of waste brine is feasible.

研究结果显示以废液再腌渍的梅胚在可滴定酸含量、可溶性固形物含量、盐度等方面均较高，但官能品评方面则无明显差异，因此将废盐液重复使用於梅胚腌渍的构想初步可行，且再生盐亦可於二次腌渍时利用。

以花楸幼胚为外植体的研究表明：(1)取材时期和激素浓度配比是影响花楸幼胚丛生芽诱导效果的主要因素。

When young embryos of Sorbus pohuashanesis were taken as explants, the following results were obtained:(1) The collection period of young embryos and the concentration and combination of hormones were the principal influencing factors for shoot regeneration from the young embryos.

以花楸幼胚为外植体的研究表明：(1)取材时期和激素浓度配比是影响花楸幼胚丛生芽诱导效果的主要因素。

We took young embryos, mature embryos, stem segments of tissue-cultured shoots, tender leaves and stem segments of adult trees as explants, two high effective in vitro culture systems of Sorbus pohuashanesis plants were established through adventitious shoot and axillary bud regeneration approaches for the first time.

我们以幼胚、成熟胚、无菌茎丛的茎段、成年树的嫩叶和茎段等为外植体，首次通过不定芽和腋芽增殖途径建立了两套高效、可靠的组培再生系统。

The rule of growth and decline about main biochemical material (solubility protein, solubility sugar, SOD and gossypol IAA) contacting with stomatic embryogenesis showed that content of solubility protein and SOD activity was differed in the different period, being lower in earlier callus and reaching maximum in 120 day.

对陆地棉愈伤组织诱导及体细胞胚发生过程中的主要生化物质（可溶性蛋白含量、可溶性糖含量、SOD活性和IAA氧化酶活性）的测定表明，各个时期的可溶性蛋白含量、SOD活性是不同的，在愈伤组织形成初期较低，随着愈伤组织的生长及胚状体的形成，可溶性蛋白含量、SOD活性逐渐上升，在120d时达最大值；而可溶性糖含量在60d时有一个高峰值，在120d时达到最低值；IAA氧化酶活性在60d、120d时酶活较高，90d的酶活较低。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
