title: Nutritional quality and ions uptake to PTNDS in soybeans.
abstract: Porous-tube nutrient delivery system (PTNDS) allows high control of the root environment and prevents plant infections in both microgravity and ground conditions. In this paper, six soybean cultivars ('ZH13', 'ZH57', 'LD10', 'HH35', 'HH43', and 'ZGDD') were evaluated in terms of yield, photosynthetic efficiency, insoluble dietary fiber and ions uptake efficiency. Besides proximal composition, the concentrations of mineral and isoflavones were monitored in the seeds. 'HH35' and 'ZH13' plants showed much higher yield and harvest index, in addition to the lower lignin content of inedible biomass. Data showed that 'HH35' had the higher photosynthetic efficiency of soybean leaves with regard to photosynthetic rate and instantaneous carboxylation efficiency, whereas chlorophyll ratio and carotenoids content were no difference with the other cultivars. Both cations and anions except NH4(+) and H2PO4(-), were accumulated excessively compared to controls, especially with anions in PTNDS.
