| 摘 要： | 以2个菊芋品种南芋一号(Nanyu No.1)和青芋二号(Qingyu No.2)为试验材料,采用砂培方式研究了150mmol/L NaCl胁迫下不同浓度KNO3对菊芋幼苗生物量及光合能力的影响.结果表明,1)无NaCl胁迫下,随KNO3浓度的增加,2个菊芋品种幼苗生物量,叶绿素含量及净光合速率均出现不同程度的减小.2...

| Abstract: | Effects of KNO3 under salt stress on the biomass and photosynthetic capacity of two varieties of Helianthus tuberosus seedlings(Nanyu No.1 and Qingyu No.2) treated with NaCl(0 and 150 mmol/L) and different levels of KNO3(2.5,5,10,20 and 30 mmol/L) were studied by pot/sand experiments in a greenhouse.1) Compared with the control(NaCl 0 mmol/L),the biomass,chlorophyll(Chl) content,and net photosynthetic rate(Pn) of two varieties of H.tuberosus seedlings declined as the KNO3 concentrations increased.2) Under 1... |
