Abstract
Within the EUFRIN apple rootstock trials, seven apple rootstocks are being tested for their resistance to ARD (apple replant disease) in several European countries.
The current paper focuses on the effects of rootstock and soil type (ARD vs. fresh soil) on the accumulation of phenolic compounds in apple fruit.
This research was performed at the Lithuanian trial site.
Accumulation of phenolic compounds in fruit tissues was enhanced in replanted soil.
On average, total phenol content in fruit flesh increased by 25%, and in fruit peel by 31%. Hyperoside and rutin in fruit flesh, and hyperoside, reynoutrin, phloridzin, and procyanidin C1 were the most variable among detected phenolic compounds, and their content in fruits from ARD soil was by 50-77% higher than in fruits from the fresh soil.
The content of (-)-epicatechin in fruit flesh and (+)-catechin and procyanidin B1 in fruit peel was similar in both ARD and fresh soil.
Rootstock had a significant effect on phenolic compound accumulation, but this effect was modified by soil conditions.
Soil type had no effect on total phenol accumulation in fruits (flesh and peel) grown on Pajam 2 rootstock.
Also, a stable phenol content in fruit flesh was on G.11 and M200 rootstocks, and in fruit peel on G.41. The highest increase of total phenol content at replant conditions was recorded on B.10 (by 66% in flesh and 60% in peel) and on G.935 (by 68% in flesh and 47% in peel) rootstocks.
