Solution
yes, parthenocarpy and apomixis are different phenomenon.
Importance of Parthenocarpy
- The fruit production without fertilisation of the ovary is called parthenocarpy. This phenomenon is applied for the commercial production of seedless fruits. e.g., banana, grapes.
- This is more useful far the juice industries.
Importance of Apomixis
- During apomixis, chromosomal segregation and recombination does not occur. So characters are stable for several generations.
- It simpilfiers commercial hybridised production because isolation is not necessary to produce F 1 F1 or maintain parental generation.
- Adventive embryony is being used in the production of uniform root-stock and virus-free varieties.
