| description | The purpose of these studies is to assess the adaptive resistance of the apple tree to winter stresses in terms of physiological and biochemical parameters, to identify the most resistant varieties for cultivation in the Krasnodar region. Objects of research are apple varieties of various origins: Orfey, Idared, Ligol, Prikubanskoe. It was found that the cryoprotective function of water-soluble sugars was maximally manifested in the varieties Orfey and Ligol, their content increased by 2.56 and 2.7 times, respectively. Soluble proteins made the greatest contribution to the formation of a protective response in Orfey and Prikubanskoye varieties in January, their content increased 1.8 and 1.9 times, respectively, compared to December. The protective function of anthocyanins was maximally manifested in December in the Orfey variety, in the bark of which their content increased by 5.6 times. Physiological and biochemical adaptation of apple varieties to low negative temperatures of the winter period is achieved by increasing the content of water-soluble sugars, proteins in anthocyanins in the bark and buds. According to the obtained data, the apple varieties Orfey and Prikubanskoye showed themselves to be more adaptive in comparison with other studied varieties and are recommended for cultivation in the Krasnodar region. |
