Objects of study were the group of diploid and triploid apple varieties of All-Russian Research Institute of Horticulture breeding. <...> According to the research results, triploid apple varieties in comparison with diploids have a sufficiently high level of metabolic processes. <...> In the group of triploid varieties on the background of significant content gibberellic acid 15.23-33.74 g/g vs 8.57-of 18.78 mg/g of diploids, in the bark of shoots, the activity of amylases increased by 31.85% and high sugar content of 3.54-5.12% compared with the diploid varieties – 2.96-4.48% are determined. <...> In addition, triploids have more intense level of respiratory 0.77-1.21 ml 2/Р·С МШЦpКrОН tШ НТpХШТН ЯКrТОtТОs – 0.64-0.77 ml 2/Р·С, КЧН activation of redox processes. <...> Determination of free proline does not reveal differences between the study groups. <...> However, the determination of total protein showed that the group of triploid apple varieties were characterized by high content in the bark of total protein of 4.70 to 6.20 mg/g vs of 3.70-4.00 mg/g of diploids. <...> The comparative analysis showed that triploid apple varieties in comparison with diploids have sufficiently high level of metabolic processes. <...> Ciurea D.

яблони селекции ВНИИСПК. <...> В результате исследований установлено, что триплоидные
сорта яблони по сравнению с диплоидами имеют достаточно высокий уровень обменных
процессов. <...> В группе триплоидных сортов на фоне значительного содержания
гиббереловой кислоты 15.23-33,74 мкг/г, против 8.57-18,78 мкг/г у диплоидов, в коре
