Effects of (S) - (+) -abscisic acid (S-ABA) on the growth and carbohydrate accumulation in root of radish were examined.When imbibed seeds were soaked in S-ABA solutions of lower then 50 ppm, stored at 5C for 2 weeks and then sown in pots, the successive bolting was inhibited. Moreover, treatment with S-ABA solution of higher than 100 ppm inhibited the germination.When cotyledons of radish were treated with S-ABA solutions of 1 to 100 ppm, fresh weight of the root decreased at higher treatment. At the same time, the treatment increased the elongating growth but decreased thickening growth. As the result, T/E ratio in S-ABA treatment of 100 ppm (0.8) became higher than that in control (0.6). Moreover, soluble carbohydrate levels in root were not affected by S-ABA treatments.S-ABA is a natural plant hormone. Therefore, it is expected that S-ABA treatment on radish may be harmless for human body. Moreover, it may be useful a damage of the quality.

研究了（S）-（+）-脱落酸（S-ABA）对萝卜生长和根系碳水化合物积累的影响，结果表明，用低于50 ppm的S-ABA溶液浸泡萝卜吸胀种子，在5 ℃下贮藏2周后播种，可抑制萝卜抽薹。1 ~ 100 ppm浓度的S-ABA处理萝卜子叶，根鲜重随浓度的增加而降低。同时，处理提高了伸长生长，但降低了增厚生长。结果表明，100 ppm的S-ABA处理的T/E比（0.8）比对照（0.6）高。S-ABA是一种天然的植物激素，对根系中可溶性碳水化合物的含量没有影响。因此，S-ABA处理萝卜可能对人体无害。此外，它可能是有用的质量的损害。
