Dynamics of Vitamins and Phenols of Alchemilla subcrenata by Diurnal Variation of Temperature in October

Round-the-clock dynamics of phenols and vitamins В6, С, РР in the leaves of Alchemilla subcrenata with a glance of thermal change was shown. The maximum of content of phenols and vitamin С was observed at 6 a.m. Dynamics of vitamins В6 and PP, actively participating in the exchange of proteins and amino acids, also is subject to fluctuation during the day. More higher content of these coenzymes are the coolest time of the day. To confirm the possible involvement of vitamins В6 and PP in the biosynthesis of proteins were examined stress proteins in leaves of Alchemilla subcrenata during those same days. Heat-shock protein HSP 17.6 was detected only a day at its maximum daily temperatures and сold regulated protein COR14b was detected in the morning, when the temperature was minimal.
