e0“Sub-low soil temperature in spring can cause stress to the apple roots”
e7“Most of the genes associated with C and N metabolism (MdBMY3, MdSS3, MdPFK6, MdCS2, MdNPF4.4, MdGS and MdGDH1) were upregulated under sucrose treatment, as confirmed by transcriptomic data”

- Intervention effect Low root-zone temperature significantly inhibited root N uptake, especially NO3−-N.
- Intervention effect Low root-zone temperature decreased photosynthesis and chlorophyll fluorescence in apple leaves.
- Intervention effect Low root-zone temperature decreased root activity by 68.85%.
- Intervention effect Low root-zone temperature inhibited growth of apple above-ground parts.
- Intervention effect Exogenous sucrose significantly alleviated the low-temperature inhibition of root and above-ground growth.
- Intervention effect Sucrose accelerated carbon metabolism in apple roots.
- Intervention effect Sucrose increased sugar, acid and ATP contents in apple roots.
- Intervention effect Exogenous sucrose alleviated the low-temperature inhibition of root N uptake.
- Intervention effect Exogenous sucrose increased the NO3−-N content in apple roots.
- Intervention effect Exogenous sucrose increased the activities of NR, GS and NADH-GOGAT in apple roots.
- Intervention effect Exogenous sucrose increased the activities of GPT and GOT in apple roots.
- Intervention effect Sucrose treatment upregulated MdBMY3, MdSS3 and MdPFK6 among genes of C and N metabolism.
- Intervention effect Sucrose treatment upregulated MdCS2 and MdNPF4.4 among genes of C and N metabolism.
- Mechanism Sucrose may enhance apple root N uptake by increasing luteolin and sinapyl alcohol accumulation in flavonoid metabolism.
