Physiological Reaction of Seedlings of Puccinellia tenuiflora Under the Condition of Salt Stress──Ⅰ. Effect of Salt Stress on the growth of Puccinellia tenuiflora seedlings
This paper concerns with the studies of growth of Puccincllia tenuitlora seedlings treated by mixed salt modeled the salt component of the soil of Songnen alkalixed grassland. Inhibition of salt stress on increase of length of the part above the ground of P. tenuifiora seedlings is stronger than the part under the ground, but the inhibition on increase of fresh weight of the part under the ground is stronger than the part above the ground.
