Integrated media and plant growth regulators comparative evaluation for enhanced in vitro propagation and acclimatization of Selenicereus Costaricensis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundseveral protocols were tested for in vitro propagation of dragon fruit Selenicereus costaricensis (F.A.C. Weber) S.Arias & N. Korotkova ex Hammel, but face limitations such as low multiplication rates, slow growth, and poor rooting and acclimatization. Media composition affects morphophysiological properties and dragon plant growth throughout all propagation stages. This study presents a comprehensive and optimized protocol for in vitro micropropagation and ex vitro acclimatization of S. costaricensis, addressing these challenges. Tip explants from two-week-old seedlings were cultured on Murashige and Skoog (MS) and Woody Plant Medium (WPM) at varying strengths (¼, ½, ¾, and full) and sucrose concentrations (20 and 30 g/L).
resultsThe optimal shoot proliferation was attained on ¾-strength MS medium supplemented with 30 g/L sucrose, yielding shoots with an average length of 1.9 ± 0.0003 cm and a fresh weight of 1.36 ± 0.057 g per plantlet. The multiplication of ¾ MS supplemented with 2 mg/L BAP and 0.5 mg/L kinetin yielded the best proliferation rate, producing 70.66 ± 0.577 shoots per explant. Rooting was markedly improved on ¼ MS with activated charcoal, yielding roots averaging 13.6 ± 0.0004 cm in length and 21 ± 0.0004 roots per plantlet. During acclimation, plantlets cultivated in a peat moss: perlite (1:1) mixture attained a 97 ± 1.000% survival rate, produced 3.6 ± 0.577 shoots per plantlet, and developed vigorous root systems. .
conclusionTo optimize in vitro propagation of dragon fruit plantlets, use ¾ MS medium with 30 g/L sucrose for establishment, add 2 mg/L BAP for multiplication, then transfer axillary shoots to ¼ MS with activated charcoal for rooting, and acclimatize using a 1:1 peat moss–perlite mix.
