Many woody crop plants such as grapevine are traditionally grown with scion varieties grafted onto rootstocks. The selection of an appropriate rootstock provides a powerful tool to manage the growth and fruiting of the scion (Jones, 2012). In the grapevine propagation, the use of rootstocks is not a new matter. The evidence of the use of rootstocks can be found out even in works written by the ...

The cultivar and rootstock effect on iron chlorosis were studied. The results revealed significant differences among peach cultivars and rootstocks in mineral content. Seasonal changes were also found in the macroand micronutrient content of leaves of peach cultivars and rootstocks. The rootstock St. Julien 655/2 was found to be efficient in K, P, Zn, Fe, Cu absorption and better than seedling ...

The effect of foliar spray of different chemicals on the sorghum cultivar KH-333 in four type nutrient medium viz; normal pH, high pH, high bicarbonate (10 mM) and, high pH (8.0) &high bicarbonate (10 mM) on biochemical parameters and the recovery of iron chlorosis in fodder sorghum was examined. The effect of iron chlorosis and sulphydryl compounds on the antioxidant enzymes and active iron co...

As interest in how to increase biomass production through biotechnological means gains traction, focus is turning towards the use of photoautotrophic micropropagation under elevated levels of carbon dioxide (CO2) to maximize plant growth and productivity. The effect of super-elevated CO2 with cold cathode fluorescent lamps (CCFLs) on the photoautotrophic growth of Oncidesa in vitro has been stu...

Twenty-eight 1-ethyland l-p ropyl-5-substitu ted imidazoles were synthesized and their bleaching activity was evaluated by using the lettuce seedling test. 5-Phenyl1-propylimidazole (1) caused distinct chlorosis, while none o f the com pounds with various alkenyl groups at the 5-position o f the im idazole ring showed this bleaching activity. In troduction o f a brom o, chloro, fluoro, methyl o...

The ability of a commercial (Aldrich Chemical Co.) humic acid (AHA) to ameliorate the photo-induced toxicity of polycyclic aromatic hydrocarbons (PAHs) was examined using Lemna gibba L. (G3). Plants were exposed to anthracene and benzo(a)pyrene both with and without AHA and grown under visible light as well as lighting that simulates relative abundances of UV-A and UV-B in natural sunlight (SSR...

Pseudomonas syringae pv. tomato DC3000 produces the phytotoxin coronatine, a major determinant of the leaf chlorosis associated with DC3000 pathogenesis. The DC3000 PSPTO4723 (cmaL) gene is located in a genomic region encoding type III effectors; however, it promotes chlorosis in the model plant Nicotiana benthamiana in a manner independent of type III secretion. Coronatine is produced by the l...

To determine if chlorosis caused by tentoxin, a toxin produced by Alternaria tenuis Nees., is due to interference with chlorophyll synthesis directly or to disruption of normal chloroplast development, the effects of the toxin on these processes in cucumber (Cucumis sativus L.) and cabbage (Brassica oleracea L., var. capitata) were studied. Cucumber cotyledons are highly sensitive to the toxin ...
