- Abstract
【Objective】 In order to explore the related factors affecting Thompson Seedless grape seed-setting and provide theoretical basis for the control of the grape seed-setting in Xinjiang. 【Methods】 The stem tension and the stem Lignin and cellulose contents of easy-dropping Thompson Seedless grape and resistant-dropping Red Globe grape were measured and the separation zone, the separation layer and the fruit brush of the mature Thompson Seedless and Red Globe were observed by staining section, and after that, the separation zone, the thickness of the separation layer and the cell cross section, the separation zone and the cell longitudinal and transverse diameter were measured; After 2, 4-D, PCPA and girdling treatment, the breaking rate and breaking force were measured. 【Results】 The pull force of Red Globe stem was (6.7±3.2) N, the pull force of Thompson Seedless stem was (2.1±0.5) N, the Lignin and cellulose contents of Red Globe stem were higher than those of Thompson Seedless, the range of Thompson Seedless zone was larger and narrower. Red Globe had a wide brush, the cells in the abscission layer were closely arranged, the cells in the abscission layer were small and loose. There was no significant difference in the shape of the cells in the abscission zone and abscission zone between the two kinds of grapes. The vascular bundles of the fruiting pedicles of Thompson Seedless and Red Globe passed directly through the free zone and distributed radially in the free zone cells. The vascular bundle cells in the free zone of Red Globe were more and denser than those of Thompson Seedless, and had thicker vascular bundle cells than those of Thompson Seedless. the percentage of no-nucleated white and the tensile force of stem were increased, and girdling treatment was the most effective. 【Conclusion】 The comprehensive comparative analysis between Red Globe and Thompson Seedless showed that the grapes with large stem pulling force has the characteristics of well-developed vascular bundles, tight connection between vascular bundles and pulp, small area away from fruit, and high content of lignin and cellulose.
