Abstract:

【Objective】 To study the effects of different scions on the survival rate of grape grafting and root characteristics of rootstock and lay a foundation for selecting suitable rootstock-scion combinations.【Methods】 Three different rootstocks including 5BB, 1103P and Shanhe 1 were branch grafted with scions including Hutai 8, Red Globe and Suxin 1, respectively.The survival rate of each combination was counted and the root growth, physiological and biochemical characteristics and the anatomical structure of root tips was observed by paraffin section method.【Results】 Among the nine rootstock and scion combinations, the four rootstock-scion combination with higher grafting survival rate were Suxin 1/ Shanhe 1, Red Globe/ Shanhe 1, Suxin 1/5BB and Hutai 8/Shanhe 1, which were 74.33%, 65.67%, 63.33% and 60.00% respectively.while the graft survival rate of Hutai 8/5BB, Hutai 8/ 1103P and Red Globe/ 5BB combinations were all lower than 40.00%.The root number of Suxin 1/ Shanhe 1 rootstock-scion combination was the highest in three different soil layers, and Hutai 8/Shanhe 1 rootstock-scion combination was the second; Compared with the rootstock-scion combinations of Red Globe/ 1103P, Red Globe/ 5BB and Hutai 8/ 1103P, the root activity, soluble protein content, soluble sugar content and SOD enzyme activity of the grafted seedlings of Suxin 1/ Shanhe 1 rootstock combination were significantly higher than those of these rootstock-scion combinations.Different scions had different effects on the diameter, area, density, xylem area and stele area of rootstock root system.The results of correlation analysis showed that except the relative conductivity index, the other indexes were significantly correlated with the grafting survival rate.【Conclusion】 Different scions have effects on the survival rate, root morphological characteristics, physiological characteristics and root tip anatomical structure of rootstocks.Through comprehensive analysis, Shanhe 1 can be used as rootstock for Suxin 1, Hutai 8 and Red Globe, 5BB can be used as rootstock for Suxin 1, and the best rootstock-scion combination is Suxin 1/Shanhe 1.

摘要:

【目的】研究葡萄不同接穗对嫁接成活率及砧木根系特性的影响,为筛选适宜的砧穗组合奠定基础。【方法】以户太8号、红地球和苏欣1号品种为接穗,5BB、1103P和山河1号品种为砧木硬枝嫁接。统计各砧穗组合嫁接苗的成活率,测定各砧穗组合嫁接苗的根系生长情况、生理生化特性,采用石蜡切片法观察根尖解剖结构。【结果】9个砧穗组合中,嫁接成活率较高的4个砧穗组合分别为苏欣1号/山河1号、红地球/山河1号、苏欣1号/5BB和户太8号/山河1号,分别为74.33%、65.67%、63.33%和60.00%,而户太8号/5BB、户太8号/1103P和红地球/5BB组合的嫁接成活均低于40.00%。苏欣1号/山河1号砧穗组合的根系分别在0~5 cm、5~10 cm和10~15 cm三个土层深度的数量均最多,户太8号/山河1号砧穗组合次之;相比红地球/1103P、红地球/5BB和户太8号/1103P这几个砧穗组合,苏欣1号/山河1号砧穗组合嫁接苗根系的根系活力、可溶性蛋白含量、可溶性糖含量和SOD酶活性均明显高于这几个砧穗组合,而相对电导率显著低于这几个砧穗组合。不同接穗对砧木根系的导管直径、导管面积、导管密度、木质部面积及中柱面积均有不同程度的影响。除相对电导率指标外,其余各指标与嫁接成活率均存在极显著相关性。【结论】不同接穗对砧木的嫁接成活率、根系形态特性、生理特性及根尖解剖结构均会产生影响。山河1号可作为苏欣1号、户太8号及红地球的砧木,5BB可作为苏欣1号的砧木,最佳砧穗组合为苏欣1号/山河1号。
