in presence of salts the uptake is depressed and the normal metabolic pathways are disturbed. If the roots were grown at high salt concentration, uptake and incorporation are affected even if they are carried out in the absence of salt. NaCl and Na(2)SO(4) affect uptake, incorporation, and metabolism of (14)C leucine in different ways. There are also preliminary indications that in pea roots grown at different types of salinity, different proteins may be synthesized. Kinetin was found to inhibit incorporation of amino acids into non stressed and Na(2)SO(4) stressed roots, but promotes uptake and incorporation of amino acids into protein in NaCl stressed tissue. It seems that there are some pronounced differences between the effects of NaCl and Na(2)SO(4) salinities on the metabolism of pea root tissue.
在有盐存在的情况下,摄取受到抑制,正常代谢途径受到干扰。如果根系在高盐浓度下生长,即使在无盐条件下进行摄取和掺入,也会受到影响。氯化钠和硫酸钠以不同方式影响¹⁴C亮氨酸的摄取、掺入和代谢。也有初步迹象表明,在不同盐分类型下生长的豌豆根中,可能会合成不同的蛋白质。发现激动素会抑制氨基酸掺入未受胁迫和受硫酸钠胁迫的根系中,但会促进氨基酸在受氯化钠胁迫的组织中摄取并掺入蛋白质。看来,氯化钠和硫酸钠盐分对豌豆根组织代谢的影响存在一些明显差异。
