“…Although there are many ways to improve ARD symptoms (Pan et al, 2017), the development of improved ARD-resistant rootstocks is a long-term effective measure to prevent and control ARD (Bowen et al, 2010). The cultivation of resistant rootstocks can effectively control pests and diseases in the replanted soil, alleviate ARD caused by certain pathogenic bacteria (Rivard et al, 2012), strengthen plant stress resistance, and increase fruit yield and quality (Zhu and Saltzgiver, 2020).…”

The cultivation of resistant rootstocks is one of the more effective ways to mitigate apple replant disease (ARD). We performed an ion current test, a pot experiment, and a pathogen infection test on the apple rootstocks 12-2 (self-named), T337, and M26. The ion current test showed that exposure to ARD soil extract for 30 min had a significant effect on K+ ion currents at the meristem, elongation, and mature zones of the M26 rhizoplane and on Ca2+ currents in the meristem and elongation zones. ARD also had a significant effect on Ca2+ currents in the meristem, elongation, and mature zones of the T337 rhizoplane. Exposure to ARD soil extract for 5 min had a significant effect on K+ currents in the meristem, elongation, and mature zones of 12-2 and on the Ca2+ currents in the elongation and mature zones. Compared to a 5-min exposure, a 30-min exposure to ARD extract had a less pronounced effect on K+ and Ca2+ currents in the 12-2 rhizoplane. The pot experiment showed that ARD soil had no significant effect on any root architectural or physiological parameters of 12-2. By contrast, ARD soil significantly reduced some root growth indices and the dry and fresh weights of T337 and M26 compared with controls on sterilized soil. ARD also had a significant effect on root metabolic activity, root antioxidant enzyme activity (except superoxide dismutase for T337), and malondialdehyde content of T337 and M26. Pathogen infection tests showed that Fusarium proliferatum MR5 significantly affected the root structure and reduced the root metabolic activity of T337 and M26. It also reduced their root antioxidant enzyme activities (except catalase for T337) and significantly increased the root malondialdehyde content, reactive oxygen levels, and proline and soluble sugar contents. By contrast, MR5 had no such effects on 12-2. Based on these results, 12-2 has the potential to serve as an important ARD-resistant rootstock.

Crop rotation in fruit trees is an effective approach for addressing some of the problems of continuous cropping. To determine whether aged peach orchard soil is suitable for planting apple trees, we studied the effects of two substances abundant in aged peach orchard soil—amygdalin and benzoic acid—on the soil microbial community structure, soil enzyme activity, and the growth of Malus hupehensis Rehd. seedlings. Soils treated with amygdalin (T1), benzoic acid (T2), and a mixed solution of amygdalin and benzoic acid (T3) were used to plant M. hupehensis Rehd. seedlings. Compared with fallow (control) soil, the soil microbial community structure, soil enzyme activities, and root protective enzyme activities, leaf chlorophyll content, and net photosynthetic rate decreased in the three treatments. The biomass and root index of M. hupehensis Rehd. seedlings significantly decreased. Compared with T3, the plant height, ground diameter, fresh weight, dry weight, root length, root surface area, root volume, and root respiration rate of M. hupehensis Rehd. seedlings in T2 in 2015 (2016 in parentheses) decreased by 19.3% (12.6%), 8.7% (7.1%), 21.2% (13.3%), 9.1% (19.6%), 7.9% (25.3%), 40.7% (28.8%), 46.2% (21.1%), and 44.2% (27.5%), respectively. Compared with T3, the same variables in T1 in 2015 (2016 in parentheses) decreased by 34.9% (16.7%), 27.6% (9.8%), 53.6% (19.4%), and 50% (20.5%), 24.1% (31.4%), 55.1% (37.6%), 63.2% (28.2%), and 47.0% (28.7%), respectively. Thus, the inhibitory effect of T3 was the strongest, followed by T2 and T1. In sum, amygdalin and benzoic acid are harmful substances in aged peach orchard soil that inhibit the growth of M. hupehensis Rehd. seedlings.

“…Many methods are available to improve ARD, such as good crop rotation practices, intercropping, soil disinfection, and the use of beneficial bacterial fertilizer [11], applications of organic amendments [2], and establishing living mulches [8]. Studies showed the decrease of beneficial microorganisms in re-planted soil, the high accumulation of harmful microorganisms, and the imbalance of the microbial community structure were important factors causing ARD [12].…”

(1) Background: The cultivation of resistant rootstocks is an effective way to prevent ARD. (2) Methods: 12-2 (self-named), T337, and M26 were planted in replanted and sterilized soil. The aboveground physiological indices were determined. (3) Results: The plant heights and the stem thicknesses of T337 and M26 were significantly affected by ARD. Relative chlorophyll content (June–October), Pn (August–September), and Gs (August) of T337 and relative chlorophyll content (June–July, September), Pn (September–October), and Ci (September) of M26 were significantly affected by ARD. ARD had a significant effect on Fv/Fm (June), qP (June–July), and NPQ of T337 (June–October, except August) and Fv/Fm (June) and NPQ (June-October, except July) of M26. Additionally, ARD affected Rfd of M26 and T337 during August. SOD (August and October), POD (August–September), and CAT (July-August, October) activities and MDA (September–October) content of T338 as well as SOD (July–October), POD (June–October), and CAT (July-October) activities and MDA (July, September–October) content of M26 were significantly affected by ARD. ARD significantly reduced nitrogen (October), phosphorus (September–October), and zinc (July) contents of M26 and potassium (June) content of T337. The above physiological indices were not affected by ARD in 12-2. (4) Conclusions: 12-2 could be useful as an important rootstock to relieve ARD due to strong resistance.
