不同供铝水平对杉木幼苗生长的影响
采用土壤盆栽试验,研究不同供铝水平下杉木幼苗各生长指标、叶片中叶绿素含量和铝含量的变化情况。结果表明,随着铝浓度的增加,杉木幼苗的苗高和生物量表现出先上升后下降的变化趋势,且均在铝浓度为50mg/kg时达到最大值,并在此浓度后随着铝浓度的增加开始下降,并在铝浓度为150mg/kg时,开始对这些指标出现抑制作用;杉木根长也随着铝浓度的增加而表现出先上升后下降的变化趋势,且在铝浓度为100mg/kg时达到最大值,在铝浓度为150mg/kg时,根长明显低于空白对照,表明在此浓度下根长受抑制作用显著;铝胁迫下杉木幼苗叶片的叶绿素含量与苗高和生物量的变化趋势类似,且叶绿素a受铝的影响比叶绿素b大;杉木叶...

| Notes | 44-1267/S Chinese fir; aluminum stress; growth; chlorophyll; aluminum content Soil pot experiments were conducted to study the effects of aluminum on growth of seedlings of Chinese fir. The changes in growth indexes,content of leaf chlorophyll and leaf aluminum in seedlings of Chinese fir at different aluminum concentrations were observed and analyzed statistically. The aluminum concentrations set up were 0,50,100,150 and 200 mg/kg,respectively. The results showed that both seedling height and biomass increased initially and then decreased subsequently with the increase of aluminum concentration. The peak value appeared at the concentration of 50 mg/kg and then decreased with the increase of aluminum concentration. Inhibition was observed when the aluminum concentration was 150 mg/kg. Root length showed a similar pattern in response to aluminum except that the peak value appeared at aluminum concentration of 100 mg/kg. A significant decrease in root length was observed,compared with the control,when the concent |
