“…Growth and vigour of the trees were evaluated yearly in November at the end of the growing season by calculating the cross-section area of the trunk (TCSA) 20 cm above the graft (Layne, 1994;Lepsis & Blanke, 2006). The fruit yield of each variety (kg tree -1 ) was calculated taking into account the total fruit collected in each orchard, tree replicates with 6 trees each.…”

The growth, phenology and fruit yield of 14 Japanese plum cultivars (Prunus salicina Lindl) were studied in two newly established experimental orchards under organic and conventional management. The experiment was conducted during 2005-2011 in the province of Seville (SW Spain), an important region of Japanese plum culture. Trunk crosssection areas (TCSA), flowering, yield and tree defoliation before winter dormancy were analysed over several years. After one year, TCSA were larger in the organically managed orchard (OMO) for most of the cultivars, in the next two years they were equal, and from the fourth year, several cultivars showed significantly larger TCSA in the conventionally managed orchard (CMO). Flowering in the conventional orchard started from 2 to 6 days before and lasted for 3 to 5 days more than in the OMO. Several cultivars produced significantly more fruit in the CMO, being the average fruit yield in the organic orchard about 72% of the conventionally managed orchard. Autumn defoliation was significantly advanced in the organic orchard, especially in cultivars highly susceptible to rust (Tranzschelia pruni spinosae), a disease not adequately controlled in the organic orchard.

“…The vigour of the trees was evaluated in November every year at the end of the growing season, by calculating the trunk cross-sectional area (TCSA) 20 cm above the graft (Layne 1994;Lepsis, Blanke 2006). The beginning of flowering, full flowering and end of flowering were registered according to the BBCH scale (Meier et al 1994).…”

Pérez-Romero L.F., Daza A., Herencia J.F., Arroyo F.T. (2017): Carbohydrate and nitrogen reserves in two cultivars of Japanese plum grown under organic and conventional management. Hort. Sci. (Prague), 44: 163-170.Nitrogen and carbohydrate (soluble sugars and starch) reserves were analysed in twig samples of 'Red Beaut' and 'Showtime' Japanese plum (Prunus salicina Lindl.) cultivars cultivated in two similar experimental orchards under organic and conventional management. 'Red Beaut' is a vigorous cultivar while 'Showtime' is a middle to low vigorous cultivar. Both cultivars exhibited delayed flowering and premature defoliation under organic management. In general, there were no differences in the concentration of reserves between the two types of management for either of the two plum cultivars, and, likewise, no differences were observed between cultivars, regardless of their vigor. Additionally, reserves were also analysed in plantlets of 'Mariana 2624' rootstock (Prunus cerasifera Ehrh × Prunus munsoniana W. Wight & Hedrick) grown in a growth chamber that simulated conditions of spring and autumn periods and subjected to organic or mineral fertilisation. Plants subjected to organic fertilisation were smaller and defoliated earlier, but the sizes of carbohydrate and nitrogen reserves were similar to that of plants grown with mineral fertilisation.

Growth and vigour of the trees were evaluated at the end of the growing season in November 2012 and 2013 calculating the cross-section area of the trunk (TCSA) 20 cm above the graft (Layne 1994;Lepsis, Blanke 2006). The production was calculated taking into account the total fruit collected in all the trees on each rootstock.…”

Pérez-Romero L.F., Arroyo F.T., Santamaría C., Herencia J. . Cv. Nemaguard rootstock had larger cross-sectional areas of the trunk (TCSA), higher yields, began flowering earlier and lasted 2-4 days more. The organic management resulted in lower values of TCSA and yield, and flowering was delayed and shortened. Overall, cv. Nemaguard rootstock produced slightly larger fruit in size and heavier weight. In contrast, apricots from cv. Real Fino had slightly higher soluble solid concentration. Acidity and maturity index were similar, while colour and firmness showed high variability. In general, the organic system produced fruit with soluble solid concentration somewhat higher. In summary, in both types of management cv. Nemaguard worked better than cv. Real Fino in terms of tree vigour, fruit yield and bloom period.
