Abstract:
This paper deals with the homologous relationship between the change of the seed shape and embryo growth in the course of development of Populus adenopoda Maxima seeds by means of the fixed position observation under microtechnology and X-ray photography.Relations between the life-span of the seeds and their microenvironment have been discussed on the basis of the results of observation and experimentation. The regular pattern of the change and factors effecting the life=span of Populus adenopoda Maxim, have been determined and possible ways to prolong the life-span of the seeds discussed as well.
