Abstract

Olive is a subtropical plant that is cultivated in many parts of the world because of its high nutritional value. The present study was conducted to investigate changes in fruit and stone traits as affected by selected olive genotypes and different harvest dates under the climatic conditions of Sarpol-e Zahab County at the Dalahu Olive Research Station, Kermanshah Province, during the 2019 growing season. The experimental factors consisted of mature trees of seven superior olive genotypes, namely D1, Dd1, Gw, Ps1, Bn3, Bn6, and Ds3, and seven harvest dates: 15 July, 30 July, 15 August, 30 August, 15 September, 30 September, and 15 October. The experiment was conducted in a randomized complete block design with three replications. The results showed that genotype Dd1 had the highest fruit weight, fruit diameter, fresh and dry pulp weight, and fruit volume among the genotypes and exhibited the most favorable quantitative fruit characteristics. As the final harvest dates approached, the values of fruit and stone quantitative traits increased, with the highest fruit weight, fruit diameter, dry pulp weight, pulp percentage, and pulp-to-stone weight ratio observed at the 15 October harvest date.
