Abstract:
The peach seedlings were used as the test materials to carry out a pot experiment.The different concentrations of γ-aminobutyric acid (GABA) were applied to peach seedlings under cadmium stress conditions,and the effects of GABA on the growth and cadmium accumulation of peach seedlings were studied,in order to provide reference for the safe production of peaches.The results showed that 1.0 mg·L-1 cadmium treatment reduced plant height,biomass and photosynthetic pigment content of peach seedlings.Application of 0.1,0.5,1.0 mmol·L-1 and 2.0 mmol·L-1 GABA increased the biomass and photosynthetic pigment content of peach seedlings.The highest root biomass,above-ground part biomass,chlorophyll a content,chlorophyll b content and carotenoid content of peach seedlings were found when the GABA concentration was 0.5 mmol·L-1,which increased 36.34%,28.79%,49.86%,85.62% and 38.10%,respectively,compared with the cadmium treatment.With the increase of GABA concentration,the cadmium content in the root system of peach seedlings showed a decreasing trend,while the cadmium content and translocation factor of the aboveground part showed an increasing trend.The application of 0.1,0.5,1.0 mmol·L-1 GABA significantly reduced the cadmium content in the aboveground part of peach seedlings by 43.92%,30.86% and 16.42%,respectively,compared with the cadmium treatment.Therefore,GABA promoted the growth of peach seedlings under cadmium stress and was effective in reducing cadmium accumulation in peach seedlings at concentrations of 0.1,0.5 mmol·L-1 and 1.0 mmol·L-1.
