Other claims from this paper (13)
- Intervention effect High N application reduced tuberous root yield of sweetpotato in both years.
- Intervention effect High N application reduced the tuber/vine rate of carbon-13 in sweetpotato.
- Intervention effect High N application reduced the top-to-base gradients of sucrose, ammonia N and potassium along the stem of sweetpotato.
- Association Cultivar J26 had a higher yield than X32 under N0.
- Association Cultivar J26 had a lower yield than X32 under N120 and N240.
- Association Cultivar J26 had a higher 13C distribution to tuberous roots than X32 under N0.
- Association Under N120 and N240, cultivar X32 showed the opposite trend, a higher 13C distribution to tuberous roots than J26.
- Observation Under N0, cultivar J26 showed a steep top-to-base amino acid gradient along the stem.
- Association Under N0, J26 had a significantly lower top-to-base sucrose increase along the stem in the late growth stage.
- Association Under N120 and N240, X32 had a greater top-to-base decrease in ammonia N along the stem during the main growth stages.
- Observation Under N120 and N240, X32 showed a steep top-to-base sucrose gradient along the stem in the early growth stage.
- Association Under N120 and N240, X32 had a lower top-to-base sucrose increase along the stem in the middle and late growth stages.
- Mechanism A desirable sucrose, ammonia N or K+ gradient downward along the stem was related to the high yield of sweetpotato.
