e0“Sub-low soil temperature in spring can cause stress to the apple roots”
e1“LT treatment significantly inhibited N uptake (especially NO3−-N) and metabolism in roots”
e3“inhibited the growth of roots (root activity decreased by 68.85%) and above-ground parts”
e4“exogenous sucrose application significantly alleviated this inhibition”

- 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 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.
