Investigation of genetic parameters and phytochemical characteristics in plum under altitude change

Suitability of ecological factors is the most important factor affecting productivity agricultural activities. Sensitivity phytochemical characteristics that are direct product quality to changing environmental conditions very high. In present study, how climate change depending on altitude affects properties in plum cultivars ?Friar? and ?Fortune? fruits which were harvested at two different altitudes (200 m 800 a.b.s.), during consecutive years (2017 2018) was investigated. addition, under genotype modeling, genetic parameters determined. line with obtained results from it determined varied parallel within same latitude. Generally, amount individual phenolic compounds organic acids increased increase while general such as total content antioxidant activity decreased. Heritabilities found lower, due high difference between genotypic coefficient variation (GCV) phenotypic (PCV) than acids. Ranking both malic acid> acetic oxalic ascorbic acid cultivars. terms acids, a stable order could not be chlorogenic has come front Since cultivar/location interactions significant according bi-plot segregation, investigating changes level would more accurate.
