An increasing number of intensive, dense, and sustainable citrus plantations have fostered a growing interest in addressing the future challenges crops: increase world’s population, climate change, globalization. Nutrient efficiency absence vigorous rootstocks are required for success these plantation systems. The agronomic performances ‘Lane Late’ orange cultivar on three substandard or semi-d...

‘Tango’ mandarin is becoming one of the most demanded varieties in Mediterranean Region. However, no information on quality fruit this citrus area has been reported. In study, physico-chemical, nutritional and sensorial mandarins grafted onto Carrizo Citrange FA5 rootstocks from two locations (Sevilla Huelva) was evaluated by harvest season. The Sevilla exhibited lower levels acids sugars than ...

We compared growth patterns and morphology of fine roots of size-controlling and invigorating peach (Prunus persica (L.) Batsch) rootstocks. Peach trees were grafted on five rootstocks: a vigorous control (Nemaguard), three intermediate vigor rootstocks (K119-50, P30-135 and Hiawatha), and a semi-dwarfing rootstock (K146-43). Minirhizotron tubes were installed at the base of trees on each roots...

Among citrus rootstocks, higher specific root length (SRL, root length}d. wt) has been linked to several specific morphological and physiological traits, including smaller average root diameter, higher root hydraulic conductivity and higher rates of root proliferation. In this study, thickness of the outer tangential exodermal (hypodermal) wall and its suberin layer, number of passage cells, pr...

years. Fertilizing once in the spring with a complete fertilizer with Uramite as the nitrogen source was satisfactory. On Lakeland soil Valencia and Hamlin orange tree growth was very good when about 1, 2, and 4 pounds of 8-2-8 inorganic fertilizer was applied in the first, second, and third seasons, respectively. Timing of applications of fertilizer also was not critical for young Valencia or ...

Introduction New rootstocks for peaches have been recently introduced into the United States through commercial nurseries. Most all of these rootstocks are complex Prunus L. hybrids that are propagated asexually. Past experience with newly introduced Prunus rootstocks has shown that extensive testing is critical to avoid potential problems in commercial situations due to nonadaptation of some r...

The genus Vitis is represented by several coexisting species in Europe. Our study focuses on naturalised rootstocks that originate in viticulture. The consequences of their presence to the landscape and to native European species (Vitis vinifera ssp. silvestris) are evaluated. This study compares ecological traits (seven qualitative and quantitative descriptors) and the genetic diversity (10 SS...

Studies have shown that phenolic compounds are important in human health.The purpose of this research was to examine the influence of rootstocks on phenolic compounds. The content of individual phenolic compounds in fruits was determined by HPLC. Total flavonoids content was measured using colorimetric method. Free radical scavenging activity on stable DPPH radicals was also evaluated. HPLC ana...
