“…Similar results were also found in grapefruit applied with 0.3 % FeSO 4 .7H 2 O+0.1 % L-77(surfactant) as reported by Horesh and Levy (1981). Foliar application of Fe-sulphate was reported to increase the chlorophyll content of the leaves in kiwi (Rambolá et al 2000) and citrus (Pestana et al 2001). Physiological activity of the peach cultivars was improved with supplementation of iron in Fe-sulphate treated plants as compared to other two iron sources.…”

A pot experiment was carried out to investigate the effect of iron supplementation on physiological and biochemical status of the low-chill peach cultivars (Saharanpur Prabhat, Shan-e-Punjab and Pratap) suffered from iron chlorosis in artificially created calcareous soil. Three most commonly used iron sources viz. Fe-sulphate (1.0 % and 0.5 %), Fe-citrate (1.0 % and 0.5 %) and FeEDTA (0.1 % and 0.2 %) were sprayed on the 4th and 5th leaves from the apex of the twig. And after 1 week of spraying, observation on various physiological and biochemical parameters in leaves were recorded. Improvement in plant physiological parameters like chlorophyll content index (CCI), photosynthetic rate (P n ), stomatal conductance (g s ) and intercellular CO 2 conc. (C i ) were recorded best with the application of 1.0 % Fe-sulphate both in treated and untreated upper leaves. The maximum recovery in biochemical parameters such as total leaf chlorophyll content, superoxide dismutase (SOD) and peroxidase (POD) activity was also noted with the application of 1.0 % Fe-sulphate. However, application of 1.0 % Fe-sulphate and 0.5 % Fesulphate had similar effect for most of the parameters under study. The ability of iron sources to induce physiological and biochemical responses in iron deficient low-chill peach plants were in the following order Fe-sulphate>Fe-citrate>FeEDTA. Differential responses in plant physiological and biochemical parameters were also exhibited by the low-chill peach cultivars with regard to supplementation of various iron sources. Among the low-chill peach cultivars, Saharanpur Prabhat responded best with the application of iron sources followed by Shan-e-Punjab and Pratap.

“…The natural acceptor in the mesophyll, however, is possibly Fe(III)-citrate, although there is some recent evidence that Fe(III)-malate could be also involved (González-Vallejo et al, 1999;Larbi, 1999;Rombolà et al, 2000). The characteristics of Fe(III)-EDTA and Fe(III)-citrate reduction (with a 5:1 citrate:Fe ratio) by leaf mesophyll are similar.…”

Iron Deficiency Decreases the Fe(III)-Chelate Reducing Activity of Leaf Protoplasts

The ferric-chelate reductase (FC-R) activity of mesophyll protoplasts isolated from Fe-sufficient (control) and Fe-deficient sugar beet (Beta vulgaris L.) leaves has been characterized. Measurements were made in an ionic environment similar to that in the apoplastic space of the sugar beet mesophyll cells. The FC-R activity of Fesufficient and Fe-deficient protoplasts was dependent on light. Fe deficiency decreased markedly the FC-R activity per protoplast surface unit. The optimal pH for the activity of the FC-R in mesophyll protoplasts was in the range 5.5 to 6.0, typical of the apoplastic space. Beyond pH 6.0, the activity of the FC-R in mesophyll protoplasts decreased markedly in both Fe-sufficient and Fedeficient protoplasts. These data suggest that both the intrinsic decrease in FC-R activity per protoplast surface and a possible shift in the pH of the apoplastic space could lead to the accumulation of physiologically inactive Fe pools in chlorotic leaves.

“…lime-induced chlorosis delays vine establishment and also eventually depresses cropping. Fe-chelates, such as Fe-EDDHA, are applied in spring and there are often repeated applications throughout the growing season (Rombolà et al 2000). Fe-chelates are, however, expensive and alternatives such as naturally occurring or synthetic vivianite (hydrated iron phosphate) have been recommended (Rombolà et al 2000(Rombolà et al , 2003Marangoni et al 2003).…”

We review the development and current status of the Italian kiwifruit (Actinidia spp.) industry and highlight some of the differences between it and the kiwifruit industries of other countries, especially New Zealand. The Italian kiwifruit industry is important both nationally and internationally. Italy produces more kiwifruit than any other country apart, possibly, from China. Italy and New Zealand are the world's two biggest kiwifruit exporters. The first kiwifruit orchards were established in Italy only 40 years ago and by 2007 they occupied 26 700 ha and produced 400-500 0001 fruit each year. Most Italian kiwifruit plantings are of the cultivar 'Hayward' but there are now orchards of several new cultivars, including yellow-fleshed kiwifruit. The cultivation methods used in Italy are similar to those in New Zealand but there are some regional differences. The biggest difference with New Zealand is in the marketing of the crop. Nearly all kiwifruit from New Zealand are exported whereas most Italian kiwifruit are consumed within Italy or in other countries of the European Union.
