Determination of the most suitable explants for walnut micropropagation

Walnut is a popular and economically important species, but vegetative propagation by budding or cutting is quite difficult. In this study propagation in vitro was tested. Meristems, shoot tips, and axillary buds were taken from seedlings of J. regia 2 April 1993. Modified MS medium with 0.5 mg/L Benzyl amino purine (BAP) was used as shoot growing medium and 1 mg/L BAP as shoot poliferation medium . The best growth in the growing medium was obtained from shoot tips (2-3 mm) and cuttings (2-2.5 cm) with 1-2 axillary buds. The meristem is not a suitable explant for in vitro propagation of walnut when compared with shoot tips and axillary buds

Effect of organic and green manuring on soil quality and plant nutrient uptake in organically grown strawberry

Evaluation of the relationships between the nutritional status of plants and soil productivity features together is important for more realistic and effective use of fertilizers and soil fertility management. The aim of this study was to determine the nutritional status, soil and plant analysis of strawberry plants organically grown under climatic conditions of Yumurtalik town of Adana, Turkey. The study was conducted between 2010 and 2012. In the trial; (1) cowpea (Vigna sinensis L.), and (2) bean (Phaseolus vulgaris L.) were used as green manuring crops; and one plot (3) was used as the control (plot where green fertilizer was not used and kept as fallow). Additionally, the effects of organic commercial compost material Ekoflora (N:P:K 1.5:2:2) and compost tea that was obtained from Ekoflora were also investigated on the split plots throughout the growing season. Green manure was used in the trial conducted as four replications as treatments (control, cowpea and bean) being the main plots and farm manure used as sub plots. Fresh strawberry seedlings of 'Sweet Charlie' cultivar were used in the trial. It was found that green manure + compost tea application increased organic matter, total nitrogen and available phosphorus and potassium contents of the soil and decreased available calcium and magnesium values. The organic matter (OM) content averaged to 2.32% in green manure applications, and organic matter average value of green manure + organic manure application was 2.38% revealing that average organic matter level was increased by 0.06%. The results showed that green manure applications gave satisfactory results, even without compost tea applications.This research is a part of the doctorate study entitled as “Effects of Green Manure Under Cover and Crop Rotation in Open Field on Organic Strawberry Growing” numbered ZF ?? ??D ? ? which was supported by Cukurova University cS cRieesnetaifrich Projects Unit

Effects of grass clipping wastes on the development yield, and quality of strawberry

3rd International Strawberry Symposium -- APR 29-MAY 04, 1996 -- VELDHOVEN, NETHERLANDSWOS: 000071753100124The objective of this work is to determine the effects of grass clipping wastes (GCW) on the development, yield, and quality of strawberries growing in pots during 1993-94 and 1994-95 growing seasons at the Department of Horticulture. After studying the results from the first year the second year trials were organised again and grass + sand and soil mixture ratios were arranged as 1:4, 1:6 and 1:8. FYM: sand and soil mixture ratios of 1.2 and 1:4 were used as control. During the growing season, the percentage of living plants, their vegetative development, chlorosis, monthly yield, yield per plant, and fruit quality (TSS, average fruit weights) were investigated. The best yield per plant was obtained from a 1:4 ratio of grass and soil plus sand mixture.Res Stn Fruit Growing, Wilhelminadorp, Netherlands, Natl Res Ctr Strawberries, Meerle, Belgium, Int Soc Hort Sci, Fruit Sect, Strawberry Working Grp, M Th F Duivenvoorden, Lisserbroek, A A M van Dijk, Heeswijk Dinther, J van den Elzen, Erp, Goossens Flevoplant BV, Ens, Plantenkwekerij De Kemp BV, Horst Meterik, Rapo BV, Roosendaal, Verschuren BV, Den Hout, Belgische Fruitveiling, St Truiden, Veiling Baorgloon, Borgloon, Veiling Kampen, Hoogstraten, Rhone Poulenc, Belgium, Scotts Europe BV, Sect Benelux, Netherlands, Consorzio Italiano Vivaisti, Ferrara, Italy, Eurosemillas S A, Cordoba, Spain, Haasnoot BV, Zaltbommel, Netherlands, Minist Small enterprises Traders & Agr, Belgiu

Growing 'Heritage' red raspberry in greenhouse using organic farming methods in Adana, Turkey

The objective of this study was to analyze the possibility to cultivate the red raspberry cultivar 'Heritage' with organic farming methods in the greenhouse. This experiment has been conducted in a greenhouse in Adana from 2006 to 2007. Plants of 'Heritage' have been planted into containers with a specific substrate mixture composed of bukasi (straw mixed with effective microorganisms), organic turf, and volcanic rock. Two topics were analyzed. In the first experiment, the objective was to evaluate the effect of pruning canes at ground level after the first yield in 2006, on the autumn yield in 2007. In the second experiment, the objective was to compare the effect of liquid and solid farm manure, and microorganisms fertilizer, which have organic farming certificate, on phonological development, yield, and quality of the fruits harvested in spring and a2utumn. In comparison between 2006 an2d 2007, the pruning trial resulted in 1816.40 g/m2 yield per plot in 2006 and 813.87 g/m2 yield per plot in 2007. Pruning has not been applied in autumn of 2007. First harvest has been done in June but in both applications, the last harvest has been done in November. The fertilizer trial showed that the best results have been achieved with liquid farm manure. In the conditions of Adana, the cultivar 'Heritage' can be cultivated for "out of season production" with organic farming methods in greenhouse without heating and additional light

The performance of some strawberry cultivars grown under high tunnels in the climatic condition of adana (Turkey)

The growth and productivity of some new strawberry cultivars for Turkey were studied during the 1992-93 season under walk-in plastic tunnels at Adana. The experimental selection/cultivars H-l (day-neutral), Redchief, Lester, Honeoye, Addie, Elsanta, Chandler, Selva (day-neutral) and Tufts were used. The plants of the first 4 cultivars were prepared as fresh runners rooted in pots (FRRP). Frigo plants of the remaining 5 cultivars were added to the experimental material. All the plants were planted in the middle of July, 1992. During the growing period first flowering and harvest dates, the growth behaviour, yield per plant and soluble solid contents of the cultivars were recorded. Among the FRRP plants the highest yield (838.64 g/plant) was obtained from H-l, and from the frigo plants 'Chandler' gave the highest yield (739.19 g/plant), however, the yield of'Addie', 'Tufts' and 'Elsanta' was similar to that of'Chandler'. 'Selva' gave the lowest yield (534.35 g/plant). In the experiment the selection/cultivars H-l, Selva, Tufts and Elsanta appeared to be vigorous and the cultivars Chandler, Addie, Redchief, Lester and Honeoye were weak in comparison to the others

Effects of a fertilizer produced from the seaweed Ascophylum nodosum on strawberry yield and quality

In order to increase fruit yield and quality of strawberry, a study on six strawberry cv. (Honeoye, Redchief, Lester, Cruz, Dorit and Douglas) was carried out in a heated plastic house in 1992-93. Plants of these cultivars were obtained by rooting runner plants in plastic tubes during spring time, then replanting them in a plastic house in July 1992. Fertilizer was applied at two different doses (0.5 g/1 and 1 g/1) at 15-day interwals during the vegetation period. Fruits were sampled monthly and total soluble solids were determined. The highest yield was obtained from Douglas with 550 g/plant, followed by Dorit, Cruz, Lester and Redchief, while the lowest yield was obtained from Honeoye with 156 g/plant. Plants receiving (0.5 g/1 fertilizer) yielded 334 g/plant, vs. 315 g/plant for these receiving 1 g/1

Fruit characteristics of nine thornless blackberry genotypes

Fruit characteristics of nine semierect and trailing thornless blackberry genotypes were evaluated in Adana province, in the Mediterranean region of Turkey. Five cultivars ('Chester Thornless', 'Jumbo', 'Loch Ness' ('Nessy'), 'Navaho' and 'DirksenThornless') and four selections (Bursa-1, Bursa-2, Bursa-3 and Bartin) were characterized in 2001 and 2002. The genotypes were compared for yield, fruit weight, concentration of total soluble solid (TSS), fruit acidity, TSS / acidity ratio, pH, color and harvest periods. The highest TSS content was in 'Navaho'; the heaviest berries were in 'Jumbo'; the highest yield was in 'Chester Thornless;' and the longest harvesting period was in 'Jumbo' and 'Navaho' in both years

Effects of sequestrene FE-138 as foliar and soil application on yield and earliness of some strawberry cultivars in the subtropics

This study was conducted to determine the role and importance of Sequestrene Fe-138 application on the yield and precocity of some strawberry cultivars grown in Southern Turkey. The plants were treated with 0.2 % and 0.4 % Sequestrene Fe-138 either as a foliar spray or a soil application. The Aliso cv ranked first in yield approximately followed by Pocahontas, Cruz and Tioga. Tufts and Vista cvs produced more or less the same amount of berries. The higher yielding doses of Sequestrene Fe-138 and its administration sites in different cvs are as follow: Tufts, 0.2 and 0.4 % soil application , Aliso, 0.2 % foliar and 0.4 % soil applications. In Vista, Tioga and Pocahontas 0.4 % soil application of Sequestrene Fe- 138 have given better yields than the other applications .It is surprising that Cruz cv responded negatively to the Sequestrene Fe-138 applications. In other words both doses and foliar or soil applications decreased the yield in comparison to that of control plants. Foliar application of Sequestrene Fe-138 to Tufts (0.2 %) and Vista (0.4 %) stimulated the precocity

Analysis of sugars, organic acids and vitamin C contents of blackberry genotypes from Turkey

The paper reports the composition of some quality characteristics of five blackberry varieties ("C. Thornless", "Bursa 2", "Navaho", "Jumbo" and "Loch Ness"). Main soluble sugar and acid contents of experimental varieties were separated, identified and quantified using high-performance liquid chromatography with photo diode array spectrophotometric and refractive index detection, for organic acids, ascorbic acids and soluble sugars, respectively. According to the results, malic acid was detected as the main organic acid while citric acid was not detected in blackberry fruits. Ascorbic acid content was found very low quantity and also was not detected in all the cultivars. As for the sugars, fructose was found as the most abundant sugar and highly detected in "Navaho". However, the highest total sugar/malic acid ratio was found in cv. C. Thornless. (c) 2005 Elsevier Ltd. All rights reserved

Determination of aroma compounds in blackberry by GC/MS analysis

The aromatic composition of five blackberry cultivars (Bursa 2, Navaho, Nessy, Chester Thornless, and Jumbo) was studied. The Im-SPME (Immersion Solid Phase Micro Extraction) extraction technique was applied and the samples were analyzed by GC/MS. Furfural and its derivatives were found to be the major aromatic compounds and 5-hydroxymethyl furfural was the most abundant compound in all the blackberry varieties
