It is shown that with insufficient soil moisture watering overground and underground organs in seedlings of mountain ash is reduced by 14–29 %. The leaves of the sugar content increased by 7–9 %, saharose content reduced by 6 % and starch – by 64 %. In shoots sugar content of sucrose is reduced by 9–20 %, and starch content is increased by 100 %. In the roots of the content of sugars, sucrose and starch are reduced by 25–64 %. It is observed that in the leaves are decreased of the total (26 %) bound (13 %) and free (52 %) of water, increased duration of veins (59 %) and number of stomata (58 %) and thickened of leaves plates (7 %) and decreased the length of the stoma (13 %).
