Actinidia arguta and Actinidia purpurea are fruit-bearing vines that have been gaining increased recognition among consumers who expect tasty, natural food produced in an unpolluted environment. The berries of these plants, known as Chinese gooseberries, are smaller than the well-known kiwi fruit, have smooth skin and contain many valuable bioactive substances. The quality of food quality can be characterized, among others, by its content of mineral components, of which many are present in the fruits of these species. The aim of the study was to determine the response of Ukrainian cultivars of Actinidia arguta and Actinidia purpurea grown in north-eastern Poland to weather conditions in phenological phases, expressed as a change in the content of macroelements in fruit. A correlation was found between the sum of temperatures and of precipitation in phenological phases in 2006-2011 and the content of macroelements in fruits of the following cultivars: Figurnaja, Kijewskaja Gibrydnaja, Kijewskaja Krupnopłodnaja, Purpurowa Sadowaja and Sientiabrskaja. The research demonstrated that the concentrations of Ca, N, P, Mg and Na in fruit of the examined actinidia cultivars were significantly affected, positively or negatively, by the interaction between the cultivars and meteorological factors in individual phenophases. It was found that the content of macroelements in fruits of cv. Kijewskaja Krupnopłodnaja, Purpurowa Sadowaja and Sientiabrskaja was not significantly dependent on the daily temperatures in any of the examined phenophases. However, these cultivars significantly responded to the content of phosphorus, nitrogen, magnesium and sodium, depending on the sum of precipitation in the two first phenophases. For the cultivar Figurnaja, sums of temperatures in the phase from fruit setting to harvest were a factor significantly affecting the magnesium content. On the other hand, the sodium content in fruits of this cultivar was significantly negatively correlated with the sum of temperatures in the phase between the beginning of flowering and fruit setting.
