Abstract: the market demand for the buckeye， but because the buckeye conventional breeding way is seed propagation， reproductive slower， plus the buckeye rate is low and seeds， seedlings to inactivation rate is weak， so the unearthed， reproduction rate low， difficult to meet the market Therefore， from the flowering length， the effect of the climatic conditions and take the morphological structure， flowering length to the pollen of energy， energy， the seed vigor of pollen influence on some physiological indexes of determination to proven buckeye rate， low birth rate， low reason for improving the buckeye setting out the theoretical basis and reproduction rate， in order to improve the buckeye breeding take measures to meet the demand of the The growth of the buckeye flowering characteristicsKeywords: buckeye， Growth flowering， Dynamic measurement
Abstract: The market demand for larger Aesculus， Aesculus However， due to the way conventional breeding sow reproduction， slow reproduction， combined with the strong low Aesculus seed and easy to inactivation， the rate of seedlings less unearthed Therefore， a lower reproductive rate and are difficult to meet the market Therefore， the length of flowering period， the impact of climatic conditions， as well as the form of flower structure， flowering to the length of pollen viability， pollen viability of different conditions， the effects of seed vigor， such as the determination of some physiological indicators of Aesculus proven to lower seed-setting rate， the reasons for the low rate of reproduction， in order to improve the seed-setting rate Aesculus， reproduction rate to identify the theoretical basis， in order to improve the breeding Aesculus to take concrete measures to meet the needs of the 还有这个标题：Aesculus Growth Characteristics of Flowering and Fruiting
Corn rhizosphere， the separation of Health and the nature of a preliminary study Abstract: This paper discussed by the natural conditions of the corn plant roots separation， purification be the root of the plate， their classification identification of patterns; will be pure The re-vaccinated within the plate in the tissue culture vaccine without access to the corn roots， determine the host of the corn plant growth and development; isolated to the growth of corn in the role of Health has Yijun; Key words: corn ; Within the Health and bacteria; separation; symbiotic colonization
Abstract: With the development of the bioinformatics， EST plays an importent role in nuclear marker-developing， new gene isolation and identification， analysis of gene expression profile， anotation ot genome fuctions， gene silico cloning and so This paper introduces the principle of EST technology， technical route and the research in genetic map， physical map， isolating and identifying new gene， gene differential expression， the research in comparative genomics and the general situation of the DNA wafer This paper sumarizes the research status of EST，and makes an outlook to ESTKeywords: genome; gene; research status; EST
