Agro Morphological Properties of Plums (Prunus Domestica L.) Genotypes Grown in Van Region

Abstract

This study was conducted in the years 2010 and 2011 to determine plum genotypes naturally grown in Van region and to identify biological diversity in the region. Phenological, pomological and morphological properties of available plum genotypes were assessed and a total of 45 genotypes were monitored for two years. Among the investigated genotypes, 10 were selected as promising plum genotypes. Budburst dates of promising genotypes varied between 5-26 April, initiation of flowering dates varied between 30 April-14 May; full-bloom dates varied between 03-17 May; end of flowering dates varied between 11-24 May; and harvest dates varied between 01 August-10 September. Fruit weights of promising genotypes varied between 8.66-25.59 g; fruit widths between 22.29-31.22 mm; fruit lengths between 22.98-35.86 mm; fruit heights between 23.16-33.32 mm; seed weights between 0.59-1.45 g; seed widths between 9.56-19.23 mm; seed lengths between 11.91-20.97 mm; fruit volumes between 12.00-32.00 cm³; fruit densities between 0.80-1.53 g cm -3 fruit flesh/seed ratios between 11.50-23.09%; fruit juice titratable acidity values between 0.89-2.62%; pH values between 3.75-4.08; total soluble solids contents (TSSC) between Brix° 10.5-15.5; vitamin C contents between 9.84-29.80 mg 100g -1 , tree canopy heights between 2.30-6.00 m; and canopy widths between 2.30-7.40 m. © 2018, Centenary University.
