Abstract

Background and Aims

Rootstock type can lead to differences in scion canopy growth and fruit yield by conferring specific traits to the scion. Conferred traits may interact to alter the relationship between vine water use and fruit yield, providing a mechanism whereby rootstocks could be used to improve the water use efficiency of fruit production. This study aimed to determine whether rootstock conferred vigour and crop water use index (yield per unit water transpired) were linked.

Methods and Results

Seven rootstock genotypes, grafted with Shiraz, in a trial established over 20 years previously, were assessed over four seasons for vigour, yield and leaf physiology, and over three seasons for whole vine transpiration using sapflow sensors. There were consistent differences in rootstock conferred traits, with yield being affected to a lesser extent than vigour or vine water use.

Conclusions

The water use efficiency of fruit production was improved for Shiraz on low vigour conferring rootstocks, due to a combination of rootstock conferred effects on scion vigour, leaf gas exchange, whole vine transpiration and yield.

Significance of the Study

The study has demonstrated that rootstock conferred traits can alter the crop water use index of the scion in a mature vineyard. Consequently, accurately matching irrigation application with vigour and leaf physiology traits of the chosen rootstock has the potential to be used as a tool to optimise vineyard water use efficiency, even in fully irrigated vineyards.

砧木赋予性状影响设拉子果实生产的水分利用效率

背景与目的砧木类型通过赋予接穗特定性状而导致接穗冠层生长和果实产量的差异。赋予性状可能相互作用，改变葡萄水分利用与果实产量之间的关系，为利用砧木提高果实生产的水分利用效率提供了一种机制。本研究旨在确定砧木赋予活力和作物水分利用指数(单位水分蒸腾产量)是否相关。方法和结果在20多年前建立的一项试验中，对7种砧木基因型嫁接设拉子，在4个季节中评估了活力、产量和叶片生理，并在3个季节中使用sapflow传感器评估了全株蒸腾。在砧木赋予性状上存在一致的差异，产量受到的影响程度小于活力或葡萄藤水分利用。结论低活力砧木对穗活力、叶片气体交换、全株蒸腾和产量的综合影响，提高了设拉子果实生产的水分利用效率。研究的意义研究表明，砧木赋予性状可以改变成熟葡萄园接穗的作物水分利用指数。因此，即使在完全灌溉的葡萄园，准确匹配灌溉应用与所选砧木的活力和叶片生理特征，也有可能被用作优化葡萄园用水效率的工具。

期刊介绍： The Australian Journal of Grape and Wine Research provides a forum for the exchange of information about new and significant research in viticulture, oenology and related fields, and aims to promote these disciplines throughout the world. The Journal publishes results from original research in all areas of viticulture and oenology. This includes issues relating to wine, table and drying grape production; grapevine and rootstock biology, genetics, diseases and improvement; viticultural practices; juice and wine production technologies; vine and wine microbiology; quality effects of processing, packaging and inputs; wine chemistry; sensory science and consumer preferences; and environmental impacts of grape and wine production. Research related to other fermented or distilled beverages may also be considered. In addition to full-length research papers and review articles, short research or technical papers presenting new and highly topical information derived from a complete study (i.e. not preliminary data) may also be published. Special features and supplementary issues comprising the proceedings of workshops and conferences will appear periodically.
