Abstract In order to explore the efficiency of spraying exogenous substance at leaf surface in enhancing the
storage and transport（ST）quality of cucumber seedlings，this paper investigated the effect of Oligosaccharides，
Zhuangmiao No.1 and plant perplex on the quality of cucumber seedlings on 0，3 and 6 days after ST．The results
showed that Zhuangmiao No.1 could control seedling overgrowing，increase root dry weight and maintain higher
seedling index，specific leaf weight and leaf chlorophyll content．While，the effects of Oligosaccharides and plant
perplex on various growing indexes of seedling were very limited．Therefore，we recommend spraying Zhuangmiao
No.1 at leaf surface to improve the quality of commercial cucumber seedling after ST．
