Production of grape and blackberry in unheated greenhouse at very high elevation and short vegetation conditions

Abstract: Erzurum province is located 1900 m a.s.l and has very short vegetation period. Thus grape

and blackberry production is not possible in the province due to lack of heat summit and short

vegetation period. In this study we aimed to attempt if grape and blackberry production is possible in

summer months in unheated greenhouses in Erzurum. We used black (cv. Karaerik) and white (cv.

Narince) grape cultivars and Bursa II blackberry cultivars in experiment. Fruit weight, fruit width,

fruit length, the number of cluster per shoot, SSC (Soluble Solid Content), titratable acidity, vitamin C

and pH of cv. Bursa II blackberry were 4.10 g, 19.73 mm, 21.06 mm, 5.43, 12.5%, 1.05%, 40 mg/100 g

and 2.3. For cv. Karaerik and Narince grape cultivars, average fruit weight, fruit width, fruit length,

cluster weight, SSC, titratable acidity, vitamin C and pH were 4.68 and 3.69 g, 17.81 and 18.17 mm,

21.58 and 18.37 mm, 276 and 362 g, 16.4 and 14.2%, 1.65 and 1.43%, 3.3 and 6.9 mg/100 g and 2.9 and

2.9, respectively. The results indicated that it is possible to growth blackberries and grapes in

unheated greenhouse condition at 1900 m a.s.l and contribute fruit diversity in Erzurum province.
