- Abstract
【Objective】 To compare and analyze the effects of 6 diffterent rootstocks on leaf appearancetraits, chlorophyll content and leaf tissue structure of Crimson seedless grapes in the hope of providing a theorelical basis for screening out rootstocks that are more conducive to leaf development of the grapes.【Method】 The Crimson seedless grape grafted with 6 rootstocks of 5BB, 101-14MG, 110R, 5C, SO4, and Betta were used as the test materials, and its grafted root seedlings and their own root seedlings were used as double controls for the study. Furthermore, the leaves, petioles, The chlorophyll content and leaf skin thickness, palisade tissue thickness, sponge tissue thickness and other leaf tissue structures were measured.【Results】 Grafting of 6 rootstocks with Crimson seedless grapes affected their leaf characteristics, chlorophyll content and leaf tissue structure. Among them, the leaf length (145.92 mm), leaf width (202.35 mm) and leaf area (145.69 mm²) of the Crimson seedless grape grafted with rootstock 5BB were 17.02%, 21.69% and 33.07% higher than those of Crimson seedlings, respectively. The seedlings grafted with nuclear rootstock were 15.22%, 21.36% and 33.12% higher, respectively.The 5BB rootstock grafted with Crimson seedless could significantly improve the leaf quality. Crimson seedless grafted with 5BB performed best in petiole length (124.59 mm), petiole width (3.95 mm), and petiole thickness (3.60 mm), which was significantly higher than those of other treatments, indicating that 5BB was beneficial to petioles development. Rootstock 101-14MG and Crimson seedless grafted seedlings had the highest chlorophyll content (42.50), which was 19.45% higher than that of Crimson seedless grafted seedlings (35.58), but 4.78% lower than that of the self-rooted seedlings (44.53); different rootstocks and Crimson seedless grafting had different effects on the leaf tissue structure. Among them, the thickness of the leaf tissue of the Crimson seedless grape grafted with the rootstock 110R (207.80 μm), the thickness of the epidermis (21.48 μm), the thickness of the fence tissue (55.94 μm), and the thickness of the sponge tissue (109.75 μm) were significantly higher than those of other stocks and stock combinations. Compared with the control group, it was significantly improved, and the leaf tissue structure was the best.【Conclusion】 Based on various indicators, among the 6 rootstocks, 5BB grafted Crimson seedless leaves and petioles have the best appearance traits. Rootstock 101-14MG and grafted Crimson seedless have the highest chlorophyll content. Rootstock 110R grafted Crimson seedless leaf tissue structure is the best, so rootstocks 5BB, 101-14MG, and 110R are excellent rootstocks that might be more conducive to the growth and development of Crimson seedless leaves.
