EVALUATION OF THE EFFICIENCY AND PROSPECTS OF THE USE OF IRON NANOAQUACHELATE IN VITRO PLANT CULTURE

Abstract

The paper presents studies of the effect of nanoaquachelate of iron on the growth processes of tobacco plants-regenerants in in vitro plant culture. Morphological features of Nicotiana tabacum L. shoots were compared with the use of FeEDTA, in conditions of its deficiency, and with the use of nanoaquachelate solutions. The peculiarities of the development of regenerating plants of tobacco in conditions of iron deficiency are shown. It was established that under the conditions of long-term cultivation (28 days) with the use of iron nanoaquachelate at a concentration of 140 μg/ml, regenerating plants did not show any signs of inhibition of vital activity, chlorotic depigmentation or aging compared to the control. Anatomical and histochemical features of regenerating plants of tobacco, which were cultivated on nutrient media with different forms and iron content, are shown.
