Embryo Rescue Techniques

• Embryo rescue involves culturing embryos to obtain viable progeny from difficult hybridizations
• Embryos can be cultured directly or within the ovule to prevent damage during excision
• Embryo rescue can overcome seed dormancy and study seed development and germination
• Media, growth regulators, and osmotic potential affect the success of embryo rescue
• Young embryos require complex media and high osmotic potential to prevent premature germination
• Older embryos have a higher chance of successful rescue due to their ability to synthesize growth substances
• Temperature and light requirements vary among species, with incubation typically at 25-30°C
• Cold treatment may be required for species with seed dormancy
• Embryo rescue is commonly used in interspecific and intergeneric hybridizations
• It is also used in breeding for seedless grapes and to produce triploids from diploid-tetraploid crosses.

Embryo rescue is a fascinating technique used to obtain viable progeny from difficult hybridizations by culturing embryos. In this quiz, you will learn about the benefits of embryo rescue, the challenges that come with it, and the different factors that affect its success. From media and growth regulators to temperature and light requirements, this quiz will test your knowledge on all things embryo rescue.
