These observations show that reprogramming is easier in interspecific embryos reconstructed with ES cells than that reconstructed with somatic cells, and that ES cells have the higher ability to direct the reconstructed embryo development normally than fibroblast cells. Oocytes were reconstructed with outbreeding Kunming albino mouse ES cells and enucleated rabbit oocytes, and the effects of the passages of ES cells and 6-DMAP on the development of interspecific reconstructed oocytes were analyzed. The interspecific reconstructed ES-rabbit oocytes were activated either by combined two set electric pulses and 6-DMAP or by two set electr

以上结果显示，6－DMAP能增加胚胎干细胞异种重构卵的卵裂率，对重构卵囊胚的发育率影响不大；高培养代数和低培养代数的胚胎干细胞用于异种核移植不影响异种重构卵的卵裂率和囊胚发育率；用胚胎干细胞作为供核细胞；比体细胞作为供核细胞所构建的异种重构胚更容易进行重编程，并且胚胎于细胞指导异种克隆胚胎正常发育的能力强于体细胞。

The correlations of eleven floral and fruit quantitative traits of Liriodendron interspecific hybrids(L. chinense×L. tulipifera) and its parent species were analysized.The aglycone and glycoside of flavonoid and carotinoids of perianth segment in the three groups were studied qualitatively and quantatively by high performance liquid chromatography.The results were as followed: The aglycone such as cyanidin, 6-hydroxyflavone and trans-chalcone and the glycoside such as glucose, rhamnose and galactose were discovered in Liriodendron interspecific hybrids and Liriodendron chinense,carotinoids such as lycopene and β-carotene were also discovered.

本文对鹅掌楸、北美鹅掌楸和杂交F_1的花果共11 个数量性状进行分析，并应用高效液相色谱对上述三大类群花被片类黄酮糖苷配基和结合糖及类胡萝卜素进行了定性和定量研究，结果如下：鹅掌楸和杂交鹅掌楸花被片类黄酮糖苷配基为花青素、6-羟基黄酮和反式查尔酮，糖苷配基结合糖为葡萄糖、鼠李糖和半乳糖；类胡萝卜素为β-胡萝卜素和番茄红素。

Mandschurica and F. vesca. To study the effect of Fragaria interspecific hybrid breeding on molecular level, the 14 accessions from interspecific hybrids of 2 crosses combinations between F. nilgerrensis and F. ananassa and 10 accessions from interspecific hybrids between F.

在杂种后代中观察到了亲本黄毛草莓、东北草莓及凤梨草莓不同栽培品种的特征带型，从而从DNA分子水平初步证实了黄毛草莓、东北草莓与凤梨草莓种间杂种的真实性。

Just the CTK content, the ABA content in its tiller node were most significantly related and most significantly negatively related to the tiller number of intervarietal hybrid respectively, but beside the CTK content, the ABA content in its tiller node were significantly related and significantly negatively related to the tiller number respectively, the IAA content were also most significantly related to the tiller number of interspecific hybrid, this may be the reason why the interspecific hybrid had a high fertile spike heterosis.

品种间杂种分蘖盛期分蘖节仅细胞分裂含量与分蘖数呈极显著的正相关，而脱落酸含量与其分蘖数呈极显著的负相关。而种间杂种分蘖盛期分蘖节中的细胞分裂素含量与其分蘖数显著正相关、脱落酸含量与其分蘖数呈显著负相关，另外其分蘖节中的生长素含量也与其分蘖数呈极显著正相关，IAA在种间杂种中的共同参与可能是种间杂种具有较强的分蘖成穗能力的原因。

The cytogenetics of interspecific hybrids among the four cultivated cotton species were studied in this paper and results are as follows: The diploid interspecific hybrid (G. arboreum×G. herbacium) F〓 had a four-chromosome-ring at the meiotic metakinesis. The synapses of tetraploid hybrid (G. hirsutum ×G. barbadense) F〓 was found to be regular, which mainly formed bivalents, sometimes some univalents, multivalents and chromosome bridge.
