How is growing roses by artificial methods useful?
Answers
The layering method is used for Jasmine plant. for Rose is stem cutting. These methods are by vegetative propagation
Tissue culture can be carried out in any season to produce plants. Plants which do not produce viable seeds and seeds that are difficult to germinate can be propagated by tissue culture. Rare and endangered plants can be propagated. Disease free plants can be produced by meristem culture.
Explanation:
we can grow artificial roses by grafting, cutting ,layering and micropropagation.
The propagation of roses can be performed by different ways : 
- By plant division and layering (for hardwood species).
- For other species (sarmentous rosebush and hybrids) by grafting and propagation by cuttings
- By seeding (as for all species giving grains).
- "in vitro" propagation : a very short time , 1 to 2 months instead of 12 to 18 months with upper methods.
Remenber: Roses with patent can�t be propagating for 17 years after their date of introduction without paying a royalty to the patent holder.
