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
