Abstract
[Objective] To investigate the physiological indexes of Hippophae rhamnoides and its relationship with cold resistance under the different low temperature.[Method] One-year old Russian Hippophae rhamnoides branches was used as experimental materials,and through-30——10 ℃ low temperature stress treatment, measured water content, osmotic adjustment, the relationship protected activity index and cold resistance.[Result] After low temperature treatment, shoots free water / bound water ratio was small, and MDA content changed with temperature regularly;Soluble sugar, soluble protein content with temperature showed the opposite trend;With decreasing temperature, the protection activity of Hippophae rhamnoides increased.[Conclusion] Hippophae rhamnoides has strong cold resistance, regulating system stability through physiological indices, with strong osmotic adjustment ability.关键词
