Other claims from this paper (14)
- Intervention effect Fine root production was lower on M.9 rootstock than BC rootstock.
- Intervention effect Fine root mortality was lower on M.9 rootstock than BC rootstock.
- Intervention effect Fine root production was lower on SH.40 than BC rootstock.
- Intervention effect Fine root mortality was lower on SH.40 than BC rootstock.
- Intervention effect M.9 interstems reduced fine root production and mortality relative to BC rootstock.
- Intervention effect SH.40 interstems reduced fine root production and mortality relative to BC rootstock.
- Association Root number density followed root length density patterns across rootstocks and interstems.
- Observation About half of M.9 tree fine roots occurred in the top 0–20 cm of soil.
- Observation In BC trees, 55.15% of fine roots occurred at 100- to 150-cm depth.
- Intervention effect Interstems did not change soil-depth distribution of fine roots.
- Observation Across rootstocks and interstems, roots living less than 80 days were generated in spring and summer.
- Observation Across rootstocks and interstems, roots living over 81 days were produced almost year-round.
- Association Lower fine root number was associated with dwarfing in dwarfing rootstocks and interstems.
- Association Average root length was not associated with dwarfing.
