| 中文摘要 | The aluminum (Al) tolerance of saffron (Crocus sativus L.) in hydroponics and the method of improving Al tolerance were investigated. Compared with the Al-free control, saffron root elongation was decreased by 59.3 and 75% at 0.05 and 0.2 mM Al stress, respectively. At 0.5 mM Al stress, the root elongation was inhibited completely. Addition of 1 mM polyamines improved saffron root growth markedly at 0.2 mM Al stress. Putrescine (Put) showed better amelioration effect than spermidine (Spd) and spermine (Spm). The root elongation in Put treatment was only 15% lower than that of Al-free control. The alleviation of Al rhizotoxicity by polyamines might be attributed to lower Al content in the root tips, and subsequent less lipid peroxidation and oxidative stress. Higher activities of amine oxidases and Hydrogen peroxide (H2O2) content might decrease the effects of Spd and Spm on alleviating oxidative damage compared with that of Put. |
