本研究以‘檀桥板栗’为试材，定期采取正常发育的雄花、雌花以及果实，采用

This study uses'Tanqiao Chestnut' as the test material, and regularly takes normal development of male flowers, female flowers and fruits. Field observation and paraffin section methods are used to carry out cell anatomy research on the development of chestnut male flowers, female flowers and fruits to determine chestnut flowers and fruits. The cytological development law of fruit development, the use of histochemical staining technology, to find out the law of nutrient transportation and transformation during the development of male flowers, ovules and embryos of chestnut; transmission electron microscopy technology is used to clarify the ultrastructural characteristics of anther and ovule development, Provide a theoretical basis for scientific regulation and high yield of chestnut flowers and fruits. The main findings are as follows:

This study took 'sandalwood chestnuts' as the test material, regularly adopted normal development of male flowers, female flowers and fruits, using field observation method and paraffin slicing method, to carry out chestnut male flowers, female flowers, fruit development of cell anatomy research, to determine chestnut flowers Cytological development laws of fruit development, using tissue chemical dyeing technology, to detect the laws of the transport and transformation of nutrients in chestnut blossoms, embryo beads and embryo development, and to clarify the ultra-microstructure characteristics of the development of flower medicine and embryo beads by using transmissive electroscopy technology, To achieve the scientific regulation and production of chestnut fruit to provide a theoretical basis. The main findings are as follows:

In this study, 'tanqiao Castanea mollissima' was used as the test material. The normal development of male flower, female flower and fruit were taken regularly. The cellular anatomy of male flower, female flower and fruit development of Castanea mollissima was studied by field observation and paraffin section method. The cytological development law of flower and fruit development of Castanea mollissima was determined. The development process of male flower, ovule and embryo of Castanea mollissima was explored by histochemical staining technology The ultrastructural characteristics of anther and ovule development were elucidated by transmission electron microscopy (TEM) in order to provide theoretical basis for scientific regulation and high yield of chestnut flowers and fruits. The main results are as follows<br>
