摘要

Inorganic nutrient concentrations in leaves, xylem sap and fruit from 'Hort16A' kiwifruit (Actinidia chinensis Planch. var. chinensis) vines grafted onto eight inter-specific rootstocks [A. deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson var. deliciosa; A. eriantha Benth.; A. hemsleyana x eriantha; A. macrosperma C.F. Liang; A. chrysantha Merr.; A. kolomikta (Maxim. et Rupr.) Maxim.; A. kolomikta (Maxim. et Rupr.) Maxim.; and A. polygama (Sieb. et Zucc.) Maxim.] were measured over three seasons. The nutrients analysed were phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn) and boron (B). The objectives of these studies were to identify rootstocks which induced relatively high or low levels of nutrients in the scion cultivar, and to correlate the nutrient concentrations of the fruits with the incidence of storage disorders. The use of inter-specific clonal rootstocks had a substantial effect on the accumulation and concentration of inorganic nutrients in the fruit, leaves and stem sap of 'Hort16A' kiwifruit vines, but few consistent relationships were observed between fruit nutrient concentrations and the incidence of storage disorders. Vines on A. hemsleyana x eriantha accumulated high levels of P in their fruits, leaves and xylem sap, and high levels of Ca and Mg in their leaves and xylem sap. Vines on A. macrosperma accumulated high levels of K in their fruits and leaves. In general, vines on rootstocks with low vigour (i.e. A. polygama; A. kolomikta) accumulated relatively low levels of nutrients. The incidence of physiological pitting, a mineral-related storage disorder, was higher in fruit with lower Mg concentrations. While rootstock-induced differences in the vigour of vines had an important role in determining nutrient concentrations in fruits and leaves, some rootstocks clearly had a stronger inherent ability to absorb nutrients from the soil than others, independent of their effect on vine vigour.

Liang et A.R.弗格森（Ferguson）美味A. eriantha Benth .; A. hemsleyana x eriantha; A.Macrosperma C.F.梁A. chrysantha Merr .; A. kolomikta（Maxim。et Rupr。） A. kolomikta（Maxim。et Rupr。）和Polygama（Sieb。et Zucc。）Maxim。]在三个季节中进行了测量。分析的养分为磷（P），钾（K），钙（Ca），镁（Mg），铁（Fe），锰（Mn），锌（Zn）和硼（B）。这些研究的目的是鉴定在接穗栽培品种中诱导较高或较低营养水平的砧木，并将果实的营养水平与贮藏障碍的发生率相关联。种间无性系砧木的使用对'Hort16A'奇异果藤的果实，叶片和茎汁中无机营养素的积累和浓度具有实质性影响，但观察到的水果营养素浓度与贮藏发生率之间几乎没有一致的关系。失调。 A. hemsleyana x eriantha上的藤蔓在其果实，叶片和木质部汁液中积累高水平的P，在其叶片和木质部汁液中积累高水平的Ca和Mg。宏观上，A。macrosperma上的藤蔓在其果实和叶片中积累了高水平的K。通常，活力较低的砧木上的藤蔓（即多枝A木;科洛米克ta）积累的养分水平相对较低。镁含量较低的水果中，与矿物质有关的贮藏障碍的生理性点蚀的发生率较高。尽管砧木所引起的葡萄活力差异在确定果实和叶片中的养分含量方面起着重要作用，但某些砧木显然比其他作物具有更强的从土壤吸收养分的固有能力，而与藤蔓活力无关。
