Compatibility of some plum varieties to Siirt ecological conditions and determination of fruit quality characteristics

Phenological, morphological, pomological and phytochemical observations, measurements and analyzes of 6-year-old Black Amber, Black Diamond, Angeleno, Santa Rosa, Can and Papaz plum cultivars were carried out in Siirt-Kurtalan ecological regions. In phenological observations, bud burst, first stem, full stem, end of surgery, harvest start date, time between full stem and harvest; morphological features, tree features; In pomological observations, it keeps fruit width, fruit length, fruit weight, SSKM and fruit pH. In chemical analysis, analyzes were made to determine the amount of phenolic substances. As a result of the observations, depending on the varieties; bud swell was between 14-28 February, bud burst 20-27 March, first bloom was between 28-29 March, full bloom was between 02-07 April, end of flowering was between 10-17 May and harvest was between 26 June and 15 July. As a result of the measurements and analyzes; fruit weight 10.60 g (Can) and 136.78 g (Santa Rosa), fruit width 26.00 mm (Can) and 63.87 mm (Santa Rosa), fruit length 25.56 mm (Can) and 58.07 mm (Santa Rosa), fruit thickness 11.77 mm ( King) and 20.50 mm (Santa Rosa), kernel weight 2.37 g (Can) and 5.09 g (Santa Rosa), meat/seed weight ratio 2.98% (Can) and 29.19% (Santa Rosa), SÇKM 7.6% (Black Diamond) and 14.01% (Santa Rosa), pH values were determined in the range of 3.73 (Can) and 4.32 (Santa Rosa).
