Effects of Exposing Potato Tuber Seeds to UV Radiation on Growth, Yield and Yield Quality

Abstract

Abstract
An experiment with randomized complete block design with three replicates were carried out in the fields of Iraq i.e. College of Agriculture, Abu-Ghraib, Baghdad, Iraq by exposing potato tuber seeds (class Elite) for the spring season and (class A) for autumn season to UV radiation for 0, 15, 30, 45, 60, 90 or 120 min. a week before planting, to investigate the effects of UV radiation on vegetative growth, yield and yield quality. Results show that most exposing treatments increased the peroxidase enzyme activity and stem number in spring and autumn seasons. For the spring season, tuber number and total yield for all exposure treatments increased significantly compared to control treatment. Total soluble solids for both seasons yield increased in exposed tuber seeds. Dry matter, starch, and specific density increased significantly in tubers exposed to 120 or 15 min. to UV radiation for spring and autumn seasons.
