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
