Compost Application

Ökológiai termesztésű almaültetvényben eltérő komposztadagok (0, 10, 25 és 50 kg N·ha−1) hatását vizsgáltuk a talaj tápelemtartalmának változására (0–30 és 30–60 cm-es mélységben). Mértük az egyes almafajták (Golden Delicious és Pinova) levelének szárazanyag- és Ca-tartalmát, továbbá vizsgáltuk e paraméterek alakulásának egymáshoz való viszonyát.A szabadföldi kísérletet a Debreceni Egyetem Kertészettudományi Intézetének Pallagi Kísérleti Telepén, a talaj- és növényminták analízisét az Agrokémiai és Talajtani Intézet laboratóriumaiban végeztük.A 2011. és 2012. évi eredményeket összevetve lényeges csökkenés mutatkozott a talaj AL-oldható P-tartalmában. Az évek múlásával jelentősen nőtt azonban a talajban a nitrát-, ammónia-, szerves-N és CaCl2-Mg tartalom a kijuttatott komposztadagok hatására. Az AL-K, -Ca, -Mg, a CaCl2-P, -K mennyisége és a pH közel azonosnak mondható.Az első kísérleti évben (2010-ben) még nem volt hatása a komposztnak. 2011-ben már észleltünk hatást, de a fagykár miatt nem volt termés a fákon. 2012-ben a nagy termésterhelés mellett is növekedést tapasztaltunk a szárazanyag-tartalom alakulásában mind a Golden Delicious, mind a Pinova fajták esetében. Adott kezeléseken belül az eltérő termésmennyiségekkel, továbbá az évjárattal összefüggő tendenciákat fedeztünk fel. A rendkívül csapadékos évben (2010) alacsony, míg az aszályos évben (2012) nagy szárazanyag-tartalom értékeket mértünk a levélben. A Golden Delicious és a Pinova esetében kapott tendencia fajtától, kezelés- és termesztés-technológiától függetlenül hasonló.A komposzt hatására 2010-ben a Golden Delicious leveleiben kismértékű, a Pinova leveleiben szignifikáns Ca-tartalombeli növekedést mértünk. Az évjárat hatásáról elmondható, hogy csapadékos évben a szakirodalmi adatoknál magasabb, míg száraz, terméshiányos évben alacsonyabb Ca-tartalommal számolhattunk. Bár a Ca-szintek alakulása tendenciájában megegyezett a két almafajta esetében, mégis megállapítható, hogy a Pinova leveleinek elemtartalma nagyobb volt, mint a Golden Delicious fáké.A levelek szárazanyag-tartalma és Ca-tartalma között fordított arányosságot bizonyítottunk.

The amounts of anthocyanins, flavonoids, total polyphenol and ascorbic acid in seven apple cultivars from Romania were investigated. The amounts of polyphenol and flavonoids in pulp and skin of apple cultivars ranged between 17.18�7.52 mg GAE/g DW and 20.10�11.06 mg CE/g DW as well as 3.64�1.18 mg GAE/g DW and 10.31�5.57 mg CE/g DW, respectively. The highest and smallest values of ascorbic acid both in the skin and the pulp were observed in the cultivars Mutsu and Starkrimson. The anthocyanin content is positively correlated with the colour intensity of the apple epicarp, being about three-fold higher in Prima than Golden Delicious cultivar. The better antioxidant activity provided by the content of polyphenol, ascorbic acid and flavonoids was in apple fruits of Mutsu cultivar and for this reason it should be regarded as a valuable source of antioxidants.

Four different varieties of apples have been considered (Limoncella, Annurca, Red Delicious, and Golden Delicious) to estimate the extent of colon polyphenolics release after in vitro sequential enzyme digestion. Since several studies report a positive effect of apple polyphenols in colonic damage, we found of interest to investigate the colon release of polyphenols in different varieties of apples in order to assess their prevention of colonic damage. UHPLC-HRMS analysis and antioxidant activity (ABTS, DPPH, and FRAP assays) were carried out on the apple extracts (peel, flesh, and whole fruit) obtained from not digested samples and on bioaccessible fractions (duodenal and colon bioaccessible fractions) after in vitro digestion. Polyphenolic content and antioxidant activities were found to vary significantly among the tested cultivars with Limoncella showing the highest polyphenol content accompanied by an excellent antioxidant activity in both flesh and whole fruit. The overall trend of soluble antioxidant capacity from the soluble duodenal phase (SDP) and soluble colonic phase (SCP) followed the concentrations of flavanols, procyandinis, and hydroxycinnamic acids under the same digestive steps. Our results highlighted that on average 64.2% of the total soluble antioxidant activity was released in the SCP with Limoncella exhibiting the highest values (82.31, 70.05, and 65.5%, respectively for whole fruit, flesh, and peel). This result suggested that enzymatic treatment with pronase E and viscozyme L, to reproduce biochemical conditions occurring in the colon, is effective for breaking the dietary fiber-polyphenols interactions and for the release of polyphenols which can exercise their beneficial effects in the colon. The beneficial effects related to the Limoncella consumption could thus be of potential great relevance to counteract the adverse effects of pro-oxidant and inflammatory processes on intestinal cells.

Early performance (6–8 yr) of Macspur McIntosh, Golden Delicious, and Spartan apple (Malus domestica Borkh.); Fairhaven peach [Prunus persica (L.) Batsch.]; Montmorency sour cherry (P. cerasus L.); and Lambert sweet cherry (P. avium L.) trees, tissue cultured (TC) on their own roots, was compared with that of the same cultivars budded on commercially used rootstocks. TC trees of all apple cultivars were similar in size to trees budded on Antonovka seedling or M.4 and exceeded the size of trees budded on M.26. They were delayed in flowering and in cropping compared with trees budded on M.26 and M.4. No difference in titratable acidity, soluble solids, flesh firmness, weight, flavor, and color between fruit from TC trees and from trees on M.4 and Antonovka seedlings was detected in 1 yr of measurement. However, fruit from TC Golden Delicious was more russeted and fruit from TC Spartan had more soluble solids. The difference in fruit appearance between TC and budded trees may result from a root-stock effect or a difference in budwood source, because Spartan fruit from trees on M.4 was more russeted than Spartan fruit from TC trees, but was not different from Spartan fruit from trees on Antonovka seedling. Trees of Macspur McIntosh on TC M.26 and on stool-layered M.26 were similar in size and yield efficiency. TC Fairhaven was larger in size than Fairhaven on Siberian C seedling, but was less yield efficient. No difference in fruit size, flesh firmness, or color was detected between fruit harvested from peach trees on the different roots. Montmorency and Lambert TC and on F12/1 were similar in tree size, respectively, but Montmorency and Lambert TC were more yield efficient than on F12/1. Fruit of TC Lambert was lighter in color and had higher titratable acidity than that of Lambert on F12/1, perhaps a result of earlier fruit maturity.

An electron microscopic study was performed on haustoria of Phytophthora cactorum (L. et C.) Schroeter developed in tissues of two cultivars of apple fruits: a susceptible variety ('Golden delicious') and a resistant one ('Belle de Boskoop'). Ultrastructure of intercellular hyphae and some aspects of their penetration between contiguous host cells were described. A light dissolution of the host cell walls was observed. Ontogenic investigations indicated that in the susceptible host, the wall of the fungal haustoria was covered with a dense-stained extrahaustorial matrix. Its origin and its polysaccharide nature were demonstrated. On the other hand, the resistant host developed, immediately after the inoculation, a papilla which gave rise, later on, to a sheath enclosing adult haustoria. The role of these callosic structures in the phenomenon of resistance was discussed.
