IN VITRO SHAROITIDA ARONIA MELANOCARPA (MICHX.) ELLIOT OʻSISH VA RIVOJLANISHIGA YOG"OCHSIMON O"SIMLIK MUHITI (WPM) OZUQA MUHITINING TA'SIRI

The effect of WPM (Woody Plant Medium) on the growth parameters of Aronia melanocarpa (Michx.) Elliot explants under in vitro conditions was evaluated. According to the experimental results, no callus was formed and the leaves remained entirely green in the control treatment, whereas explants cultured on WPM medium showed a significant increase in fresh weight, with green-reddish leaves and reddish pigmentation in the stems. Moreover, the average number of microshoots and the total number of leaves were several times higher compared to the control, and callus formation was observed at the stem base. These results indicate that WPM is an effective medium for stimulating the micropropagation of A. melanocarpa
