摘要

修剪方式对葡萄产量的影响主要体现在不同的层次上。在通常受修剪影响的特征中,已知束的数量对同化源和吸收功能之间的关系有显著影响。此外,生育力会受到遮荫的显著负面影响。在本研究中,我们旨在研究2017年和2018年连续两年,在Sahebi和Halagho两种红食葡萄品种中,轻、中、重度修剪4、6和8个芽对每根甘蔗的影响及其相互作用。2018年,轻度修剪的“哈拉哥”和每根甘蔗有8个芽,使串数增加了54.00,价值最高。结果表明,与营养性芽相比,顶芽结果较多,头芽1 ~ 4个;根据本研究的结果,可以得出结论,由于葡萄藤修剪施加的压力,因此,化学成分增加以减轻负面后果。2018年,两种品种的全浆果抗氧化活性均显著降低,其中“萨赫比”下降幅度更大。通过增加茎长或芽载/茎来增加束数。综上所述,修剪方式对束数、抗氧化活性和长期累积储量都有影响,因此选择和应用特定的修剪方式至关重要。因此,强调该领域进一步研究的重要性。

BUNCH NUMBER AND ANTIOXIDANT ACTIVITY IN ‘SAHEBI’ AND ‘HALAGHO’ GRAPES AFFECTED BY PRUNING INTENSITY AND CANE LENGTH
Pruning methods can primarily affect grape production at various levels. Of the commonly affected features by pruning, the number of bunches has known to have a significant effect on the relation between the functions of assimilate sources and sinks. Further, fruitfulness can significantly be negatively influenced by shading. In this study, we aim to study the impact of 4, 6 and 8 buds per cane with pruning intensity as light, moderate and severely pruned and their interaction in the course two consecutive years, 2017 and 2018 in ‘Sahebi’ and ‘Halagho’ (both seeded red table grape cultivars). In 2018, lightly pruned ‘Halagho’ and having 8 buds per cane increased number of bunches by 54.00, which had the highest value. Results showed that there is apical buds bear more fruit by comparison to the buds with vegetative nature, 1 to 4 first buds. Based upon the outcomes of this study, it could be concluded that due to the stresses imposed by the pruning of the vines, therefore, the chemical compounds increases in order alleviate the negative aftermaths . In 2018, whole berry antioxidant activity in both cultivars was significantly lessened, and this decline was higher in ‘Saahebi’. The number of bunches was increased by increasing cane length or bud load/cane. Overall, the pruning program has an impactful role in bunch number as well as antioxidant activity and in the long-run on accumulated reserves, which makes choosing and applying a specific pruning method undeniably important. Thus, emphasize the importance of further research in this field.
