以‘江淮1号’、‘江淮2号’杨为试验材料,‘I-69’杨为对照,研究水胁迫下3个杨树品种各项生理生化指标的变化.3个参试品种在W3(浅度积水,土壤水分过饱和)处理下,60 d后高生长量表现为‘江淮2号’杨＞‘江淮1号’杨＞对照‘I-69’杨,盆栽苗木保存率分别为40％,33％和25％;W2(无积水,土壤水分完全饱和)、W3淹水处理下,‘江淮1号’杨、‘江淮2号’杨的苗生物量明显大于‘I-69’杨;W3处理下‘江淮2号’杨超氧化物歧化酶(SOD)、含糖量变化幅度最小,且数值均明显低于‘江淮1号’杨和‘I-69’杨,‘I-69’杨叶片的丙二醛(MDA)含量增幅较‘江淮1号’、‘江淮2号’杨大.3个杨树品种叶绿素在W3处理下60 d后的含量分别为‘江淮2号’杨(3.61 mg/g)＞对照‘I-69’杨(3.36 mg/g)＞‘江淮1号’杨(3.27 mg/g).采用数据处理软件及隶属函数法,对几个杨树品种的耐涝性进行综合评价,结果表明:在淹水胁迫处理期间‘江淮2号’杨、‘江淮1号’杨比对照‘I-69’杨表现出较强的耐涝性,适合在安徽省江潍、沿淮、湖泊等地势低洼处造林.
The waterlogging resistance of ‘Jianghuai’ poplar cultivars
Variation of physiological and biochemical indexes of three cultivars poplar ‘ Jianghuai No.1 ’,‘ Jianghuai No.2’ and the control poplar‘ I-69’ under water stress were studied in this paper.The order of height increment of three cultivars after treating 60 days with treatment W3 (shallow water,soil moisture saturation) was poplar ‘ Jianghuai No.2’ ＞ ‘ Jianghuai No.1 ’ ＞ ‘ I-69’,and the conservation rate was 40％,33％ and 25％ respectively.Biomass of poplar ‘ Jianghuai No.1 ’,‘ Jianghuai No.2’ was both significantly higher than that of the‘ I-69’ under treatment W2 (soil moisture was completely saturated),W3.Variation of superoxide dismutase (SOD) activity and soluble content were the smallest under treatment W3.The increase of malonaldehyde(MDA) content of ‘ I-69’ poplar was higher than that of others.Chlorophyll content was ‘ Jianghuai No.2’ ＞ ‘ I-69’ ＞ ‘ Jianghuai No.1 ’ and the relative conductivity was also‘ Jianghuai No.2’ ＞ ‘ I-69’ ＞ ‘ Jianghuai No.1 ’ after treating 60 days under treatment W3.Waterlogging resistance of three cultivars of poplar were evaluated with subordinate function method,the results showed that the waterlogging resistance of ‘ Jianghuai No.2’ and ‘ Jianghuai No.1 ’ were stronger than that of the ‘ I-69’,indicating those was suitable for afforestation in the marshland,along the Huaihe River,lakes and other low-lying in Anhui Province.
