研究了不同浓度水杨酸（ Ｓ Ａ）对马铃薯脱毒试管苗生长、分化及试管微薯诱导和发育的影响。结果表明：低浓度 Ｓ Ａ 显著抑制马铃薯试管苗主茎和根的生长，促进侧枝和匍匐茎分化。高浓度（０．１～１．０ ｍ ｍ ｏｌ／ Ｌ） Ｓ Ａ 能诱导试管微薯形成并显著提高结薯率。 Ｓ Ａ 浓度为 ０．５ｍ ｍ ｏｌ／ Ｌ 时，结薯率最高，且成薯集中，薯块大小整齐一致
The effects of different concentrations of salicylic acid (S A) on the growth and differentiation of potato virus-free test-tube seedlings and the induction and development of test-tube microtubes were studied. The results showed that the low concentration of S A significantly inhibited the growth of potato stems and roots and promoted the differentiation of lateral and stoloniferous plants. High concentrations (0.1 ~ 1.0 m mol / L) of S A induced microtuber formation in vitro and significantly increased tuber yield. When the concentration of S A was 0.5 m mol / L, the tuber yield was the highest, and the concentration of potato was the same
