The effect of plant growth regulators on morphogenesis in tissue culture of some agriculture species

The vegetative propagation of the plants in in vitro conditions enables to abbreviate the process of selection, enhance the genetic stability of plants and improve the production of healthy plants free of viruses. In this paper the results of our experimental work for determination of the potential of in vitro morphogenesis and micropropagation of some agricultural species are presented (Apium graviolens L., Daucus carota subsp. sativus L., Cucumis sativus L., Cucurbita pepo var. cylindrica, Raphanus sativus var. radicola, and important agricultural species from Apiaceae, Brassicaceae, Cucurbitaceae and Solanaceae family). Different initial explants were cultivated in vitro on various media supplied by different combinations and concentration of plant growth regulators. The main objective of this research was to set up meristem tissue culture and non-meristem explants, to explore the properties of the tissues in vitro, and to observe their possibilities for morphogenesis and micropropagation
