Abstract:
Taking cucumber seedlings ‘Jinchun 4’ as material，under hydroponically culture,the effects of exogenous γ-aminobutyric acid (GABA) on growth and mineral elements contents under different NaCl concentration stress were studied.The results showed that compared with the control，the growth of cucumber seedlings were significantly inhibited and the concentration of K+，Ca2+,Mg2+reduced，but the concentration of Cl-，Fe2+，Na2+ increased with NaCl stress treatment.Meanwhile，150 mmol/L NaCl treatment had more significant effect on cucumber seedlings than that of 80 mmol/L NaCl treatment.However，exogenous GABA could effectively alleviate the inhibitory role under different the NaCl concentration on cucumber seedlings，which manifested that the fresh weight of seedlings were increased 63.58% and 117.21% than 150 mmol/L NaCl and 80 mmol/L NaCl treatment respectively.The results suggested that the harm was aggravate with the NaCl concentration increasing and exogenous GABA could alleviate the damage of NaCl stress by influencing the absorption of mineral nutrition in cucumber seedlings.
