Other claims from this paper (7)
- Observation A few explants on a kinetin-alone medium developed into rooted plants.
- Intervention effect The medium with both IAA and kinetin gave the highest frequency of plants, higher than the kinetin-alone medium.
- Intervention effect Kinetin alone caused production of many new leaves on Dianthus caryophyllus meristem explants.
- Intervention effect Development with kinetin alone was significantly less than with kinetin combined with IAA.
- Observation IAA alone caused Dianthus caryophyllus meristem explants to develop primarily callus, roots and a few leaves.
- Observation On an unsupplemented medium, continued development of Dianthus caryophyllus explants required 2 pairs of primordial leaves and a pair of expanding leaves.
- Mechanism A balance of hormonal substances synthesized in young leaf structures and relocated to the meristem is proposed to regulate new leaf initiation in the shoot apex.
