<i>IN VITRO</i> MICROPROPAGATION OF <i>ERYNGIUM MARITIMUM </i>L.
The paper is devoted to the stages of <i>in vitro</i> micropropagation for rare medicinal and ornamental plant - <i>Eryngium maritimum</i> l. It informs anout the effectiveness of applying sterilization with various disinfectants. It is found that the most optimal explants for the introduction to <i>Eryngium maritimum </i>culture are rootstocks parts, subject to sterilization with “Domestos”(100 %) for 7 minutes after immersion in ethanol for 1 minute (96 %); culture media for micropropagation and rooting of the studied species are optimized. On 1/2 MS medium, supplemented with 0,7 mg/l, 2,4-D and 4,0 mg/l of 6- BAP, the largest number of microshoots developed from the parts of rhizomes, multiplication factor averaged 7,2 ±1,3; active rhizogenesis was observed on MS medium supplemented with 1,0 mg/l of IAA. Average root length was determined to be 70,4 ±2,3 mm. Glass adaptation chambers were used with vermiculite as substrate in order to adapt the rooted plants of <i>Eryngium maritimum</i> to sterile conditions.
