| 摘 要： | 应用盆栽试验方法,采用完全随机试验设计,研究了1年生紫荆实生苗在不同土壤盐分和水分及交叉胁迫下的光合特性。结果表明:紫荆净光合速率、蒸腾速率、气孔导度随着胁迫强度增加呈现出降低的趋势,但在轻度水分胁迫时的降低最少;紫荆的细胞间隙CO2浓度随着胁迫强度的提高呈现出升高的趋势。紫荆能在较低的盐、旱交叉胁迫下正常生长,但是长时间的高强度的胁迫对紫荆是不利的。

| Abstract: | One-year-old seedlings of Chinese Redbud(Cercis chinensis)were grown in a pot with varying soil water levels,soil salt(NaCl) levels and intercross stress to determine photosynthetic characteristics.The results showed that C.chinensis net photosynthetic rate,transpiratory rate,stomatal conductance were dereased with the increase of stress and the degress of the decrease were the least ones urder light water stress concentrations of intercellular CO2 decreased with the increase of stress.Seedlings of C.chinensis could grow normdly under the light intercross stress of salt and water,bat it was disadvantageous for the growth under hight intensive stress. |
