Plant embryology

the science of plant embryo formation and development. This includes research on pre-fertilization blastocyst and pollen tube formation, fertilization process, embryo development, and the relationship between embryo development and external environmental conditions and intransigent physiology,
biochemics
and genetics. It is closely related to plant cytology, plant genetics, plant physiology and developmental biology, and is the theoretical basis of applied science such as plant breeding and plant cultivation. The discovery of pollen (
1823
is believed to be the beginning of modern plant embryology.
the middle and late
century, plant embryos developed rapidly, and extensive research was done on the structure and development of male and female lithosomes, embryo development, and the process of sexual integration, which laid the foundation of plant embryology.


1930s
, experimental research on plant embryology was carried out, and experimental embryology has been an important part of plant embryology since the
50's
. In the past
20
years, due to the infiltration of modern biology techniques and theories, plant embryology has not only made new progress in basic theoretical research, but also made great contributions to the control of sexual processes and the creation of new plant varieties. The relationship between structure and function in plant reproductive system, fertilization, embryo induction, embryo, embryo beads, sub-room, endosperm and flower medicine
culture
is the most active research field in contemporary plant embryology.
