Study Notes
Artificial Seeds and Their Applications
- Artificial seeds are developed from somatic embryos, enabling new agricultural advancements.
- This technique facilitates the propagation of transgenic plants, non-seed producing plants, and polyploids with desirable traits.
- Artificial seeds simplify the labor-intensive selection process of conventional breeding, offering cost-effective solutions to farmers.
Need for Artificial or Synthetic Seed Production Technology
- Micropropagation ensures a plentiful supply of specific plant species.
- Certain species face challenges in seed propagation due to heterozygosity, small seed size, and the need for mycorrhizal fungi for germination (e.g., orchids).
- Seedless varieties, such as grapes and watermelons, typically require vegetative propagation, which can be time-consuming and costly.
- Artificial seed production is viewed as an efficient alternative for propagating important agronomic and horticultural crops.
Characteristics of Clonal Propagation Systems
-
Micropropagation:
- Low volume and small scale.
- Ensures genetic uniformity of plants.
- Requires acclimatization of plantlets before field planting.
- High cost per plantlet with low multiplication rates.
-
Greenhouse Cuttings:
- Similar to micropropagation in volume and scale.
- Maintains genetic uniformity and requires rooting before field planting.
- High cost per plantlet with multiplication rates constrained by mother plant size.
-
Artificial Seeds:
- Supports high volume and large scale propagation.
- Maintains genetic uniformity and allows direct field delivery of propagules, eliminating transplant stages.
- Lower cost per plantlet with rapid plant multiplication.
Distinction from Commercial Seeds
- Artificial seeds should not be confused with commercial synthetic cultivars, which consist of advanced generations of open-pollinated populations made from selected inbred clones or hybrids.
