Abstract
Drought is a major abiotic factor limiting agricultural crop production. The objective of this study was to investigate the effect of triadimefon (TDM) on leaf physiology and growth of soybean in response to drought stress. Soybean variety of Nannong 99-6 (Glycine max var.) was used to study the effects of TDM on carbon–nitrogen metabolism and root structure under drought stress with pot experiment. The results showed that drought stress significantly depressed the growth and yield regardless of spraying TDM. However, drought-stressed plants treated with TDM (D+T) showed much higher biomass and yield than those without TDM (D). Leaves of D+T plants exhibited a higher relative water content and chlorophyll content, but lower relative electric conductivity as compared with those of the D plants. Formation of lots of new roots, and more mitochondria and electron density deposits in the cells of root tips in D+T plants were noticed. Foliar glucose, fructose, and soluble sugar were increased by drought during the drought stress period. TDM decreased glucose and fructose a little during stress and the beginning stage of the recovery period but increased it later in the recovery period. Activities of sucrose synthase (SS EC 2.4.1.13), sucrose-phosphate synthase (SPS EC 2.4.1.13), and glutamine synthetase (GS EC6.3.1) and contents of NO3-N were increased by TDM. Collectively, the results indicated that TDM could effectively alleviate the adverse effects caused by drought stress, which was partially attributable to modifications in morphology and physiological characteristic.
