Seed Deterioration Study in Pea, Using Accelerated Ageing Techniques

Shakeel Ahmad Jatoi, Muhammad Afzal, Shahzad Nasim and Rashid Anwar

Abstract

An accelerated ageing study was conducted on five pea varieties to assess seed deterioration behaviour during storage. Seeds of these varieties were subjected to different temperatures (25, 35 and 45°C) and storage durations (48, 72 and 96 hours). Observations were recorded for germination rate (%), speed of germination, shoot and root length (cm), shoot and root dry weight (mg). Germination rate (%) and speed of germination were significantly affected by different temperatures and storage durations. A variety dependant seedling growth rate was observed. The rate of seed deterioration increased with the increase in storage temperature and storage period. The results revealed that significant varietal differences in seed deterioration were observed and the rate of deterioration and some of the varieties were faster.
