title: Anatomy, ploidy level, and essential oil composition of &lt;i&gt;Hyssopus officinalis&lt;/i&gt; ʻNikitskiy Beliyʼ &lt;i&gt;in vitro&lt;/i&gt; and &lt;i&gt;ex situ&lt;/i&gt;
abstract: Background. Clonal micropropagation is a biotechnological method for plant multiplication. The existing data on the structure of organs in vitro , genetic stability, and essential oil composition are limited for Hyssopus officinalis L., so this study was aimead at investigating these aspects under a short period of in vitro culturing. Materials and methods. Plants of Hyssopus officinalis ʻNikitskiy Beliyʼ cultivated ex situ , in vitro and ex vitro were analyzed. Conventional methods were applied
