三种园林灌木抗性生理指标的测定及综合评价

为评价在自然条件下生长的金叶女贞、大叶黄杨、紫叶小檗的抗性强弱,于2011年7～8月和2011年10～11月取样,系统地测定了丙二醛含量、游离脯氨酸含量、SOD活性、叶绿素含量、细胞膜透性和植物组织含水量6项抗性生理指标,并用模糊数学隶属函数法进行综合评价。结果表明:大叶黄杨0.635紫叶小檗0.613金叶女贞0.467。大叶黄杨和紫叶小檗的抗性相近,均优于抗性最差的金叶女贞。以这3种园林灌木建造的彩色绿篱地段,应注意对金叶女贞的管理养护。在当地园林建设中,不宜大面积地应用金叶女贞。

Determination and Fuzzy Synthetic Evaluation of Physiological Index of Three Garden Shrubs'Stress-resistance

The stress-resistance of Ligustrum vicaryi,Euonymus japonicus Thunb.and Berberis thunbergii cv.atropurpurea under natural conditions,determination and fuzzy synthetic evaluation of physiological index for stress-resistance in July and August 2011 and October and November 2011 were evaluated.The results showed that Euonymus japonicus Thunb.0.635>Berberis thunbergii cv.Atropurpurea 0.613>Ligustrum vicaryi 0.467.Resistance of Euonymus japonicus Thunb.was similar to Berberis thunbergii cv.atropurpurea,but the resistance of them were both better than Ligustrum vicaryi.The color hedges lot using the three hedges of garden shrubs,should pay attention to the management and conservation of Ligustrum vicaryi.It was inappropriate apply a large area of Ligustrum vicaryi in local garden construction.
