Apple replant disease (ARD) is a severe problem in orchards and tree nurseries caused by yet unknown soil biota that accumulate over replanting cycles. This study tested the contribution of nematodes to ARD, cultivation Tagetes as control option. In pot experiment, patula or tenuifolia were grown ARD soil, incorporated removed. Nematodes extracted from untreated washed on 20-µm sieves induced s...

The cultivar and rootstock effect on iron chlorosis were studied. The results revealed significant differences among peach cultivars and rootstocks in mineral content. Seasonal changes were also found in the macroand micronutrient content of leaves of peach cultivars and rootstocks. The rootstock St. Julien 655/2 was found to be efficient in K, P, Zn, Fe, Cu absorption and better than seedling ...

Suitable rootstock enhances apple tree resilience. In 2021, we studied “Buckeye Gala” ( Malus domestica var. Buckeye Gala") on nine rootstocks with contrasting vigor in NS and BC, Canada. Rootstock effects vigor, yield, midday stem water potential were significant BC. After sustained heat events, the large-dwarfing Geneva 935, 4814, 969 had lower ratio of sunburn fruits, resulting higher projec...

Diverse plant virus families encode movement proteins (MPs) in their genomes. MPs are required for cell-to-cell movement of the virus in host plants and modify plasmodesmata in the cell wall, allowing cell-to-cell movement of virus particles or infectious transcripts. In recent years, much progress has been made in determining cell-to-cell movement functions of MPs from herbaceous plant viruses...

Microplot experiments were conducted over two years (four growing seasons) to evaluate Meloidogyne incognita resistance in rootstocks used for grafted tomato (Solanum lycopersicum), muskmelon (Cucumis melo), and watermelon (Citrullus lanatus). Three tomato rootstocks; 'TX301', 'Multifort', and 'Aloha', were tested in addition to the nongrafted scion, 'Florida-47'. Two muskmelon rootstocks; Cucu...
