B chromosomes do not pair with A chromosomes,they are inherited in a non-Mendelian way, exhibiting meiotic and mitotic instability andnondisjunction. Bs have little influence with the phenotype. DNA sequence differences in rye genomes (JNK population with similar geneticbackground) with and without B chromosomes were analyzed by random amplifiedpolymorphic DNA.

目前，已在约1300种植物和逾500种动物中发现了B染色体，实际含有B染色体的物种数远远不止这些。B染色体具有许多独特的性质：它独立于A染色体之外，不与任何A染色体配对，为非孟德尔遗传，具有不分离机制，不携带或极少携带核仁组织区，无影响表型的基因。

This thesis with lie to lead to acquire through the agriculture rod bacteria of turn the gene paddy rice T0 and a seeds in order to experiment the material, the adoption PCR examination and Southerns are miscellaneous to hand over the examination to combine together of method, pass the examination conversion plant posterity in the HPT( the Hygromycin phosphotransferase) gene, study the outside source gene in turn the gene paddy rice posterity of separation circumstance and heredity stability;Pass the influence to a form of form of the conversion plant carries on statistics to learn the analysis, studying the outside source gene to the conversion the sex form of plant.

本论文以通过农杆菌介导获得的转基因水稻T0和T1代种子为试验材料，采用PCR检测和Southern杂交检测相结合的方法，通过检测转化植株后代中HPT基因，研究外源基因在转基因水稻后代中的分离情况和遗传稳定性；通过对转化植株的表型性状进行统计学分析，研究外源基因对转化植株的性状的影响。

Methods Acute oral toxicity test, subchronic inhalation toxicity test and mutagenicity test were conducted to observe the effects of petroleum asphalt in experimental animals.

The results of this experiment were different from previous study which suggests that the study on plant chemical defense in large geography scale is difficult and the results may be affected by the background of seedlings and experimental animals and the measured features. So that, more experiments should be carried on in the future.

本文的试验结果与过去的相关研究结果有一定差异，说明大地理范围的植物化学防护研究并不简单，其结果可能受种前的遗传背景、实验动物背景、所选的观测指标等诸多因素影响，因此需要进一步的反复实验。

Flower color inherent and its influence on the related characters about plant, flower and fruit in eggplant were studied with the white-flowered mutant of XIANLVQIE and its maternal group.
