Abstract

Droughts and poor soils are the main agricultural constraints in Iran that have limited the cultivation of many plants. Therefore, the cultivation of plants such as barberry that are tolerant to these conditions and have good performance should be considered. Therefore, in this study, the adaptation of a commercial clone of seedless barberry was investigated in order to introduce it as a suitable orchard crop for planting in the climatic conditions of Qazvin province. Seedless barberry plants were planted in January 2019 in three geographical areas including Esmaeil Abad located in Qazvin city, Yezbar located in Abyek city and Zarabad located in Alamut city at altitudes of 1329, 1170 and 1450 meters above sea level, respectively. The factors studied included flowering time, fruit set, fruit ripening time, fresh yield of each shrub in the on year, and quantitative and qualitative characteristics of the fruit. Based on the results, the earliest date of flowering and fruit set was observed in Yezbar station with a lower altitude (1170 m) followed by Esmail Abad region (1329 m) and Alamut (1450 m). The date of fruit ripening in Alamut with a higher altitude was earlier than in other regions. The highest fresh weight of fruit per shrub in the on year (3344 g) was observed in Alamut region. The highest fresh and dry weight of 10 berries (1.5 and 0.31 g, respectively) was also observed in Alamut region. The highest titratable acid and ascorbic acid levels were related to fruits in Alamut region with a higher altitude. Based on the results, it can be concluded that the selected clone of seedless barberry showed better adaptation in Alamut region, therefore its cultivation in Alamut region is recommended.
