Abstract

The objective of this research was to evaluate the effects of 22 clonal rootstocks and own-rooted scion trees (without rootstock) on leaf nutrient contents (N, P, K, Ca, Mg, Mn, Fe, Zn, Cu and B) of the ‘Jade’ scion peach growing in a no-irrigated area with Peach Tree Short Life (PTSL) history, as well as their effects on nutrient agronomic interpretation. Macronutrient (N, P, K, Ca and Mg) and micronutrient contents (B, Cu, Fe, Mn and Zn) were determined in the first and second years after tree planting, in Pelotas-RS, Brazil. We conclude that leaf contents of P, K, Ca, Mg, B, Cu, Mn and Zn are influenced by the scion/rootstock combinations and own-rooted trees tested. Treatments changed agronomic interpretation classes of all macro and micronutrients. For macronutrients, ‘Flordaguard’, De Guia, Tardio-01 rootstocks and the own-rooted trees stood out, with leaf nutrient contents similar or even higher than trees grafted on ‘Capdeboscq’ and ‘Aldrighi’. For micronutrients, trees on GxN.9, ‘Ishtara’ and ‘Santa Rosa’ plum stood out. From a nutritional point of view, own-rooted ‘Jade’ peach trees did not present any limitations.

22个无性系砧木和自根树嫁接‘玉’桃叶片营养成分的研究

本研究的目的是评价22个无性系砧木和自根接穗树（无砧木）对“玉”接穗桃叶片营养成分（N、P、K、Ca、Mg、Mn、Fe、Zn、Cu和B）的影响，以及它们对营养农艺解释的影响。在巴西Pelotas RS，在植树后的第一年和第二年测定了大量营养素（N、P、K、Ca和Mg）和微量营养素含量（B、Cu、Fe、Mn和Zn）。我们得出的结论是，P、K、Ca、Mg、B、Cu、Mn和Zn的叶片含量受接穗/砧木组合和所测自根树的影响。处理改变了所有宏观和微量营养素的农学解释类别。在大量营养素方面，“Flordaguard”、De Guia、Tardio-01砧木和自己的生根树脱颖而出，其叶片营养素含量与“Capdeboscq”和“Aldrighi”嫁接树相似，甚至更高。在微量营养素方面，GxN.9、“Ishtara”和“Santa Rosa”李子上的树木尤为突出。从营养的角度来看，自根“玉”桃树并没有任何局限性。
