| 摘 要： | 以大豆品种南农99-6为材料,通过盆栽试验研究了α-萘乙酸对干旱和复水处理下大豆幼苗生长和光合作用的影响.结果表明:干旱抑制了大豆的生长,植株的生物量和叶面积的增长速率降低,叶片相对含水量、叶绿素含量、净光合速率、气孔导度、胞间CO2浓度和蒸腾速率等生理指标急剧下降.复水后大豆生长状况得到改善,植株的生物量和叶面积的增...

| Abstract: | Soybean(Glycine max var.Nannong99-6) was used to study the effects of α-naphthaleneacetic acid(NAA) on growth and photosynthetic characteristic of seedling under drought and re-watering with pot experiment.The results showed that drought inhibited the growth of soybean seedling.The increasing rate of biomass and leaf area decreased.Leaf relative water content,chlorophyll content,photosynthesis rate(Pn),stomata conductance to CO2(Gs),intercellular CO2 concentration(Ci) and transpiration rate(Tr) all decreased sharply.After re-watering,the increasing rate of biomass and leaf area increased.chlorophyll content,leaf relative water content,Pn,Gs,Ci and Tr all increased rapidly and almost restored to the normal level at the final stage of experiment.Pre-treatment of NAA alleviated the decrease of the increasing rate of biomass and leaf area,leaf relative water content,chlorophyll content,Pn,Gs,Ci and Tr during drought stress time.And after re-watering,it also promoted the restore of soybean and increased physiological index as compared with drought treatment.It showed that NAA could effectively enhance the ability of drought resistance in soybean at seedling stage. |
