Abstract:
With ‘Yellow Rose’，‘Rosario Bianco’，‘Xiangfei’ and ‘Zui Jinxiang’ four introducted grape varieties as materials，their quantitative distribution and relationships of base fruiting shoots，fruiting shoots，flower clusters and fruit clusters were studied.The results showed that，the diameters of base fruiting shoots and fruiting shoots，the lengths of flower clusters and fruit clusters showed phenomenon of concentrated distribution for all varieties.Diameters of basefruiting shoots of all varieties were concentrated in (1.00±0.30)cm.‘Rosario Bianco’ fruiting shoots were finer and concentrated below 1.10 cm，other varieties were concentrated in (1.00±0.20)cm.Flower clusters of ‘Yellow Rose’ were smaller，most below 10 cm; those of ‘Rosario Bianco’ were larger，most above 12 cm，and those of ‘Xiangfei’ and ‘Zui Jinxiang’ were in the middle,most in (10.0±0.30)cm.Fruit clusters of ‘Yellow Rose’ were smaller too and most were below 13 cm，those of other varieties were concentrated between 13-20 cm.Correlation analysis results showed that diameters of base fruiting shoots and fruiting shoots had no significant correlation among most varieties; there were a significant positive correlation between the diameters of fruiting shoots and the first flower clusters for the other varieties except ‘Rosario Bianco’，there were no significant correlation between the diameters of fruiting shoots and the first fruit clusters for the other varieties except ‘Xiangfei’，and there were significant positive correlation between the first flower clusters and the first fruit clusters for all varieties.These suggested robust fruiting shoots could occur bigger flower clusters and the flower cluster length before the blossom could forecast the length of fruit cluster.
