Abstract
Nitrogen (N) in different forms has been demonstrated to play significant roles in plants. However, little is known about molybdenum (Mo) effects on N absorption and utilization in grapevine seedlings grown under different N sources. The present study used a sand culture system to analyze the impact of Mo application (0 μM; 1 μM) on N absorption and utilization in grapevine (Vitislabrusca × V. vinifera ‘Shine Muscat’ (rootstock 3309 m)) young potted seedlings under different N sources (NO3−, NH4NO3 and NH4+). The different N forms and Mo application significantly influenced dry matter accumulation, and root architecture and activity. The effects of Mo on total N content followed the order of (NH4NO3 > NO3− > NH4+). Moreover, Mo and N induced VvMOT1 and VvNRT1.1 expression synergistically. Mo supply altered the utilization of NO3−, NO2−, and NH4+ in grapevines under different N sources. NH4NO3 showed the highest effect while NH4+ the least. Furthermore, the 15N-labeling experiment showed that the 15N content in shoot and root and the 15N-use efficiency were the highest after Mo application under NH4NO3 source, indicating the synergistic effects of Mo with the co-application of NO3− and NH4+ sources. The study’s findings provide insights on Mo and N fertilizer utilization for cultivation and production practices in fruits.
