ImmatureEmbryoRescueandCulture

Embryo culture techniques have many significant applications in plant breeding, as well as basic studies in physiology and biochemistry. Immature embryo rescue and culture is a particularly attractive technique for recovering plants from sexual crosses where the majority of embryos cannot survive in vivo or become dormant for long periods of time. Overcoming embryo inviability is the most common reason for ......阅读全文
