Effect of cryopreservation on apple genetic resources at morphological, chromosomal, and molecular levels.

abstract：:Artificial insemination (AI) with cryopreserved boar semen is limited to no more than 1% of the total number of inseminations due to low conception rates and litter sizes. Cryopreservation causes a dramatic decrease in the viability, motility and fertility of spermatozoa, but the underlying mechanism remains unknown. ...
