Optimization of aerial node mediated emergence and field performance in lower altitude of a higher altitude specific endangered medicinal plant, Valeriana jatamansi Jones

A study was undertaken to develop a convenient, low cost, and an efficient technique for rapid propagation from aerial node of Valenaria jatamansi Jones directly in artificial soil formulations. The performance mediated emergence also evaluated higher altitude (HA) as well lower (LA) monitor the above below ground growth parameters year addition active marker component analysis. combination supplemented (SAS) having NPK, PSB Tricoderma asperellum along with critical environment that initiated high benefit at early time point (49 days). two-node containing cutting (wt.=0.580 ± 0.156g; emergence=87.383 2.483%) showed maximum compared one (avg.=0.165 0.016g; avg. emergence=63.883 2.77). Concomitantly, injection 2 μL 6-Benzylaminopurine (6-BA; 0.25 mg.lt-1) into enhanced benefits like significantly number root initiation. 4-month-old plant produced around 10 additional nodes could be explored next round planting material production original will transplanted main field more than 90% survival rate without acclimatization hardening steps. Therefore, continuous exponential mass clonal achieved one-time requirement nodes. 235 days exposure leaves, larger petiole length, smaller leaf length breadth natural habitat grown altitude. were LA HA environment, but not total rhizome variation component. present developed first new SAS. Hence, it breakthrough Quality Planting Material (QPM) directly. easy bypass costly process tissue culture V. jatamansi, endangered medicinal plant.
