摘要：

本研究旨在比较嫁接苗与自根苗烟台地黄瓜在生长状况上的差异，并明确嫁接对烟台地黄瓜生长发育的影响。通过田间试验，对比了2种类型黄瓜的的植物学性状、果实性状、营养品质、感官质量及产量。结果表明，嫁接对烟台地黄瓜株高、茎粗、节间长有一定的促进作用；嫁接基本保留了烟台地黄瓜果实的优良性状；嫁接苗烟台地黄瓜维生素C含量有明显下降，嫁接苗烟台地黄瓜的果型、色泽喜好度高于自根苗黄瓜，嫁接苗烟台地黄瓜的果肉颜色、甜味、水分、黄瓜味、涩味、苦味、整体喜好度要低于自根苗黄瓜，二者差异未达到显著水平；嫁接可以提高烟台地黄瓜产量，增加黄瓜单果重。综上，嫁接苗与自根苗烟台地黄瓜生长状况有一定的差异。

Abstract:

In order to understand the differences in growth status between grafted and self-rooted seedlings of Yantai ground cucumber, and to clarify the impact of grafting on the growth and development of Yantai ground cucumber, field experiments were conducted to compare the botanical characters, fruit characteristics, nutritional quality, sensory quality, and yield characteristics of grafted and self-rooted seedlings of Yantai ground cucumber. The results showed that grafting had a certain promoting effect on the plant height, stem thickness, and internode length of cucumber plants. Grafting basically retained the excellent characteristics of cucumber fruits. The vitamin C content of grafted cucumber seedlings decreased significantly. The fruit shape and color preference of grafted cucumber seedlings were higher than those of self-rooted cucumber seedlings, The flesh color, sweetness, moisture, cucumber flavor, astringency, bitterness, and overall preference of grafted cucumber seedlings were lower than those of self-rooted cucumber seedlings, and the difference between the two did not reach a significant level. Grafting can increase the yield of Yantai ground cucumber and increase the single fruit weight of cucumber. There are certain differences in the growth status of cucumber between grafted seedlings and self-rooted seedlings in Yantai.

Key words: Yantai ground cucumber, grafted seedlings, self-rooted seedlings, growth, growth condition, sensory evaluation, sensory quality, yield, fruit characteristic, nutritional quality
