摘要: 以山桃幼苗为试验材料,在正常管理和碱性土壤2个环境条件下,通过生理指标测定,研究土壤碱胁迫对山桃叶片生理活性的影响。结果表明:与对照相比,碱胁迫下山桃相对电导率、可溶性糖(SSC)含量、可溶性蛋白(SPC)含量、脯氨酸(Pro)含量、丙二醛(MDA)含量、过氧化物酶(POD)活性、过氧化氢酶(CAT)活性、超氧化物歧化酶(SOD)活性均有一定程度的提高,而叶片相对含水量(LRWC)、叶绿素(Chl)含量均有不同程度的下降,可溶性蛋白(SPC)含量呈现先增加后降低的变化趋势。从以上方面综合分析,表明山桃对碱胁迫具有一定的自我调节能力,以适应不良环境。

Abstract: Taking Prunus davidiana(Carr.) seedling as test material,through determination the physiological indexes,effect of lamina physiological index were analyzed under the normal management and alkaline soil two environmental conditions. The results showed that:Under alkali stress,relative electrical conductivity,content of soluble sugar content(SSC),content of soluble protein(SPC),proline(Pro) content,malondialdehyde(MDA) content,activity of peroxidase(POD),catalase(CAT) activity,superoxide dismutase(SOD) activity were a certain degree of rise,while the content of leaf relative water(LRWC) and cross chlorophyll(Chl) were decreased,content of soluble protein(SPC) was increased after the first drop of change. Comprehensive analysis from the above aspects,which indicated that Prunus davidiana(Carr.) to alkali stress had a certain self-adjustment ability,so as to adapt to bad environment.

Key words: Prunus davidiana (Carr.), Alkali stress, Physiological activities, Adaptation
