Response mechanism of sweet potato storage root formation and bulking to soil compaction and its relationship with yield

Field experiments were performed using two sweet potato[Ipomoea batatas L. (Lam.)].cultivars (‘Beijing 553’ and ‘Longshu 9’) with significant differences in source sink characteristics. The physiological and ecological mechanisms of regulation of soil compaction on storage root yield were studied under different soil compaction treatments. The non-capillary porosity of plough horizon increased significantly during the whole growth period with the decrease of soil compactness. During storage root formation (20-40 d), the minimum temperature was significantly decreased, the maximum temperature and diurnal temperature range of plough layer were significantly increased with the decrease of soil compactness. Compared with the control, the loose treatment could increase the activities of sucrose synthase (SS) and adenosine diphosphate glucose pyrophosphorylase (ADPGPPase) in storage roots, also the starch content, the initial dry matter accumulation potential, dry matter accumulation rate and the distribution ratio of 13C assimilates from functional leaf to storage root. At harvest period the average weight per storage root and harvest index were significantly increased in the loose treatment, Beijing 553 and Longshu 9 increased production by 20.01% to 24.25% and 21.64% to 27.78%, respectively.
