About ten years ago nurseries began to test several novel apricot stocks developed either to reduce plant vigour and boost early as well as high cropping or as a more suitable replacement for Myrabolan (Prunus cerasifera) and Apricot seedling in water-logged or chlorotic soils. These stocks were the Italian bred selections of Prunus domestica Penta and Tetra, the P. cerasifera Adara and the Prunus insititia Adesoto® 101, both Spanish-bred seedlings, and Plumina®, a Prunus bessey × P. cerasifera hybrid developed in France. Performance testing was carried out under a national project. The trials were set up in 2001 in plots of pilot orchards at Imola in Bologna Province, Ancona, Caserta, Palermo and Cagliari, their soil profiles differing notably from each other. They were tested against Apricot seedling and Myrabolan 29C controls grafted to cv. San Castrese. The experimental layout was split-plot with 15 replicates per plant and the trees were trained to delayed vase. Performance results after the first seven years indicate the viability of Penta and Tetra and, contrary to expectations, that Adesoto® 101 is incompatible with apricot and Adara is too weak in heavy soils.

The effects of biodynamic production practices on composition and sensory attributes of Sangiovese wines were examined for 2 years (2009 and 2010) in a vineyard that was converted from organic (ORG) to biodynamic (BDN) viticulture. During the first year (2009), the BDN wines were characterised by low alcohol strength, colour intensity, total polyphenols, monomeric anthocyanins and catechin. Conversely, the second year BDN wines differed from the organic wines in terms of total polyphenols and phenolic compounds, including polymeric pigments, co-pigmentation, tannins and iron-reactive polyphenols. The effect of management practices, harvest and their interaction was analysed for each compound. Positive interaction was observed for total acidity, volatile acidity, cyanidin-3-glucoside, protocatechuic acid, (+)-catechin, quercetin and trans-resveratrol. ORG wine initially showed a more complex aroma profile; however, the differences were almost indistinguishable during the second year. Trained panellists highlighted differences in colour intensity between ORG and BDN wines although no preference was found by consumers. The concentrations of ochratoxin A and biogenic amines were far below the health-hazardous threshold. © 2014 Elsevier Ltd. All rights reserved. Source

The green peach aphid M. persicae is a common pest of stone fruits (primary host), but it is a very serious problem on vegetable crops (secondary hosts), because the summer generation could be vectors of several important virus diseases (more than an hundred) on many vegetable crops. The green peach aphid overwinter in Italy mainly on peach as egg and late in winter or in spring attacks flowers and shoots. In late spring it moves to other hosts, which include a wide range of weeds and commercial vegetable crops. In Emilia-Romagna the first nymphs appears on peach normally during the flowering, or a little bit after, and can damage the fruits. After two generations on peach the winged forms appear and migrate to summer hosts, where many other generations run. Depending from appearance, population level, variety and natural control normally a spray at pre-bloom is planned, but a post-bloom spray could be a right time also. To control of M. persicae at post-bloom period 3 field trials were carried out during 2012/2013 springs in 2 different farms on 3 nectarine peach varieties. One of the aphid populations was resistant suspected to neonicotinoids. The insecticides used were: spirotetramat (Spirotetramat), 2 neonicotinoids: imidacloprid [Confidor-O TEQ], thiametoxam [Actara] and 1 pyridinecarboxamide: flonicamid [Teppeki]. The results were similar in all trials and showed an excellent and long lasting (persistence) activity of spirotetramat and a good efficacy of flonicamid, but for a shorter period, as well as the 2 neonicotinoids in all trials. © 2015 ISHS.

The plum industry in Italy has shown substantial stability during the last ten years. About 14.000 hectares are currently grown using Japanese (75%) and European plum cultivars (25%). The most important destination is for fresh consumption, although a small production of dried fruits is still produced. The main growing areas are located in Emilia Romagna and Campania Regions where more than 50% of the total amount of the national commercial yield is gathered. At the recent Plum National Meeting, that was held in 2006 at Agrigento (Sicily) the main aspects related to breeding, cultivar assessment, rootstock trials, training systems and post-harvest management were pointed out. With this reference, this introductory lecture will briefly review these aspects, highlighting the most important traits of plum production in Italy as well as the development opportunities in new different areas where other stone fruits are traditionally grown.
