Pollen germination was tested on six-aged PVNA "zenjiomaru" and "shougatsu", and artificial pollination on "Fuyou" non-astringent persimmon at different temperature and sucrose concentration.

In this article,the author reviews advances in improved variety selection,clone,artificial pollination,application of fertilizers,prevention and control of plant diseases and elimination of pests in recent 20 years,and puts forward a direction in research of ginkgo cultivation in future.

Biochemical analysis indicated that biomacromolecule content in seed by artificial pollination with elite tree pollen were higher than that with scattered tree pollen.

Methods After finding Chinese Bellflower plants with aberrant anther,the natural pollination,artificial pollination and self-crossing experiments were conducted and harvested individually.

RESULT Through artificial pollination,the hermaphroditic flower ripening rates in Maoshan,Nanshan,Qinglongshan and Lingshan increased from 12.

Artificial pollination with hanging the branch and graft technique can enhance fruited capacity,but pollination with graft technique obtained a higher output.

Research on the influencing factors of artificial insemination in Boer goats;

Comparison of four artificial insemination methods in Fenneropenaeus chinensis;

Key techniques for increasing artificial insemination rate of breeding bird;

Effect of ovarian hyperstimulation on pregnant rate in intrauterine insemination;

Fertilized eggs from pond cultured parent fish were obtained by induced spawning and artificial fertilization,and the observation of embryonic and postembryonic development processes was systematically carried out during June of 2005 in Huzhou.

Gonadal maturation of barin flounder was induced by environmental and nurtrition regulation in artificial culture conditions and embryos were obtained by artificial fertilization.

Study on AI and It s Series of New Techniques in Sika Deer;

Just as AI can improve male animal reproduction efficiency greatly, embryo transplantation is an efficient way to use female animal reproductive potential fully, and enlarge elite animal population size quickly, which will help to accelerate breed improvement and pure breed reproduction.

The reproductive performance of yellow cattle after estrus ovulation synchronization and fixed time AI was compared with AI cattle after estrus synchronization in natural local yellow cattle.
