IN VITRO MODELING OF MORFOGENESYS PROCESSES IN SEQUOIA SEMPERVIRENS (D.DON) ENDL, VIA THE USE OF PHYTOHORMONES
Journal Title: Natural Resources and Sustainable Development - Year 2015, Vol 5, Issue 1
Abstract
The main objective of the study has been the realization of a screening for the role multiple types of phytohormones in different concentrations within the medium play in the initiation and unfolding of regeneration and organ-genesis processes for Sequoia sempernirens (D. Don) Endl. Our results show that explants constituting of apical and stem fragments react very well to the MS1/2 medium, with low content of macro and micro-element salts. The addition of auxins in the medium does not stimulate the root-genesis process; only the callus-genesis process is stimulated. A good multiplication percentage is obtained on mediums which have one auxin and BA -0.5mg/l in their composition.
